| Q: |
NEW! We have a 6-unit SM 72F and a 4-unit SM 72V, all manufactured between 1980 and 1990. We are planning on relocating the machines to our new factory which does not have air conditioning. Can we place the machines in the new factory without air conditioning? What is the recommended temperature range for the machines to operate properly? |
| |
| A: |
Both the temperature and relative humidity play a role in the pressroom. In printing, consistency is crucial for success. The temperature of your pressroom should remain between 68 and 76 degrees Fahrenheit and the relative humidity should range between 35% and 55%. These criteria must be met in order to ensure top performance of not only your Heidelberg presses, but also the substrate that they print on. Please consult with our Systemservice experts if you have additional questions about your move or equipment. |

| Q: |
NEW! We are experiencing repeated trip out with the breaker for the compressor on our QM 46. When the problem began this occurred maybe once a week, but more recently it happens several times per day. Do you have any solutions to this issue? |
| |
| A: |
You may need to replace your HVK board. There is a new version HVK board that is fused at a higher rating to replace your old one. Also, the pneumatic pressure switches may need replacing. We recommend having all of these electrical items replaced by a Heidelberg Technician. The newer pneumatic pressure switches are wired in a different pattern, and we therefore do not recommend repairing this without the support of a Heidelberg Service Technician.

| Q: |
FEATURED - My QM 46 randomly shuts down in the middle of the run. When this happens, the screen goes dead. To fix this, the entire machine must be restarted, which resets the plate status. This results in a forced plate eject and we lose all of the saved settings for the job. Do you have any idea why this is happening? Is there a way to tell the machine that it DOES have a plate loaded? |
| |
| A: |
All of these issues are related and can be resolved with the same fix. The wiring harness has a loose connection. You can either replace the wiring harness on the X7 plug or have a Heidelberg Service Technician reseat the wires on the existing plug with a special amp tool. The latter would be a less expensive fix. This will fix the issue of the machine losing the 5 volt connection which causes the memory loss and the screen blanking out. As far as telling the machine that the plates are still loaded, the only way to do this is to go through the autoplate method of lining up the cylinders and remounting the plates. The plates do not have to be removed to do this. Once the wire connection is fixed, the plate issue will be solved as well.
If you would like a Service Technician to help reseat the wires:

| Q: |
NEW! The light at the feeder of my QM 46 went out. I bought a replacement bulb for it but it still won’t come on. The light box on the press has the number 11E1 on it. Is there a special light bulb I need or can I use any replacement with the same value as the one that comes with the press? |
| |
| A: |
You can get an aftermarket bulb but you have to make sure it is a heavy duty bulb or it will blow out immediately. To see the difference visually, look at the prongs that plug the bulb in and follow them up to the filament. The prongs that go up to the filament go across continuously, become the filament, and come back down to the other prong. With the light duty bulb, the filament on top is a separate wire and much thinner than the posts. |

| Q: |
NEW! Recently the cylinder on our 1985 GTO 52 has been hard to turn while trying to change a plate or blanket, regardless of whether it is in manual or we use the electric button. I have no idea what is happening as it has worked fine in the past. Do you have any suggestions to fix this problem? |
| |
| A: |
It may be that the brake on the main drive motor needs to be adjusted. We would suggest you have a Heidelberg service technician visit to fix this issue.

| Q: |
FEATURED - I have a 2.5 year old Printmaster QM 46-2. The first unit has a permanent water shock mark about 3” down from the gripper edge, running across the entire sheet left to right. Running a solid in this area shows a lighter excess water mark about 2mm or less in width. Nothing I have tried will eliminate the mark, including replacing all of the soft rubber dampening rollers. Do you have any suggestions to fix this problem? |
| |
| A: |
The following are remedies for Stripe Formation Conditioned by Machines: - When maintaining the rollers, only use appropriate cleansing agents. The weekly application of a wash paste removes lime deposits, and will regenerate the rollers.
- Adjust the rollers in accordance with the instruction manual. Inspect the adjustment regularly.
- Change used rollers. The rubber surface of older rollers becomes glossy and over-smooth. At the same time, as their hardness increases, the edges bulge out in the shape of a trumpet. More pronounced abrasion becomes evident.
- Adjust reciprocation of the ink form rollers
- The dampening distribution cylinder must be kept clean and receptive to water.
- The roll bearings must be in fine working condition (no play, no sticking).
- Lubricate the roll bearings.
- Set the ink form rollers as gently as possible on the printing plate. By doing this, impacts stemming from the run-on and run-off edges are reduced.
- The bearer ring should be kept clean and grease-free.
- The calibrated underpacking should be clean, cut in a format to fit, and correctly inserted.
- Clamping between the plate and the blanket should range between .1mm and a max .13mm (.004-.051 in).
- Clamping between the blanket and the counterpressure should be set in consideration of the surface of the printing stock. Avoid clamping that is set too high.
- Always prepare dampening solution according to instructions (pH value and conductivity). The Ideal dampening solution has a water hardness of 8-12 dH, a pH-value of 4.8-5.5, and a temperature ranging from 50-59 degrees Fahrenheit.

| Q: |
NEW! Occasionally, I have trouble with the plate not coming off of the 2nd unit of my Quickmaster 46. The indicator light says that I have a plate jam (error SF 3+7 92) and I have a lot of trouble getting the error to clear. Sometimes it will clear right away and other times it takes forever. Do you have any suggestions as to how I can clear that easily? |
| |
| A: |
Your plate may not be coming off all the time due to the following.
First, it may be that the AutoPlate assembly needs to be adjusted. It could also be because the plate clamp height is not fully open. When clearing the plate error, you must take extra special care that you are following the exact sequence each time.
We would recommend a service call to ensure the proper operation and adjustment of this plate assembly. |

| Q: |
Is there a retrofit possibility for installing a laser slit fountain on a Quickmaster 46? I have a project that I could run on the Quickmaster, but I would need to have better control of ink distribution. I’ve seen that there are third party replacements for Quickmasters and wondered if I could add the laser slit ink fountain from the Printmaster 46 to my Quickmaster 46. |
| |
| A: |
There is no retrofit kit for this, but it is possible to do. To add the laser slit ink fountain from the Printmaster 46 to a Quickmaster 46, you will need to completely replace the ink fountain as well as the ink fountain roller.
A Heidelberg service technician can ensure all parts are correct and the conversion is within tolerence.

| Q: |
I am having trouble with ink "piling" on the water metering rollers on a GTO-5 with DDS dampening, is this an ink/fountain solution issue or a roller adjustment? |
| |
| A: |
Ink piling is normally an ink/dampening solution issue, where the ink is not able to withstand the strength of the fountain solution, either due to the mixture ratio or the type of solution altogether.
If it is the same solution you run normally, you most likely have a contamination issue that can be taken care of by washing the press with HOT WATER AND WHITE VINEGAR, (do not use a chemical deglaze or the like, as it is very hard on the rollers). The hot water will chase out the water based contaminates and the vinegar will chase the mineral deposits out of the rollers.
It may be necessary to do this several times to get the problem to go away, and it should be done on a weekly basis afterwards to prevent further contamination problems. |

| Q: |
I have a SM 74 that I’m having trouble getting a Color wash done. I’m using my Yellow unit to go to varnish. Can you outline a color wash procedure? I have washed 3x and still yellow. |
| |
| A: |
I would suggest for a color wash up procedure to try the following:- After the initial wash up allow a roller paste to run onto the rollers for several minutes.
- Rinse rollers as you normally would.
- As an alternative to the roller paste you could use opaque white to pull out the yellow ink.
- Double check roller setting to ensure proper contact points.

| Q: |
We are buying an MOV and I was wondering what to look in the machine as far as it’s workable condition is concerned. |
| |
| A: |
The Heidelberg MOV has been a strong printing machine for thousands of customers around the world. The M Offset had an end of life in 1995 when the Speedmaster 74 was introduced to improve quality and reduce production time. While there are many M Offset machine still producing in the industry today one can never be sure of the condition of a used machine without an evaluation. Heidelberg Service can provide a service to evaluate any used press and provide a detailed report.

| Q: |
I run a 2-color Heidelberg GTO 46 press with Kompac water systems. Unfortunately, I’m having some problems and I’m hoping for help. This is what’s happening: I think the problem is called chalking. When I overprint a second (or third) color, it does not print solid. There are spots in the printed areas that are not taking ink. Can you please help me with the solution? |
| |
| A: |
Care needs to be taken on many offset printing presses with the amount of spray powder that is applied on the first pass of a multi pass job. Excess spray powder can create difficulties in applying a second color due to a build up on the blanket. This will be apparent if the blanket has a white caulk coating on the surface. This can be removed with a water dampened sponge. |

| |
| Q: |
I’m having trouble with my coater.
It seems to come on impression with different pressures between the chrome metering
roller and blanket on the coating unit. I can run all day with the pressure up around
100 and the rate about 60 or 70, stop, load more paper, take off, and pressure will
all of a sudden come on much heavier. I’ll have to back the pressure off to about
60 and the rate down to about 10 to get the same amount of coating to keep the sheets
from sticking together. I can start back up and it will go other way. Not having
enough pressure between the chrome roller and blanket, I have to put it back to
a pressure setting of 100 and a rate of 60 or 70. I have noticed when this happens,
the speed at which the roller is spinning with the blanket also changes.
The pan
is always consistent with the rate you have it set for, the problems occur with
the metering roller. When I need less pressure and a lower pan roller speed the
metering roller is turning the same speed as the blanket. When I need more pressure
and a higher pan roller rate, the metering roller is turning slower than the blanket.
You can even see streaks, as if the blanket is being drug past the metering roller.
This has been going on for a while. If you can give me any help with this it would
be greatly appreciated. |
| |
| A: |
I’m not sure of the press format size you have, but in general,
a two roller coater requires a setting between the pan roller and chrome roller
of approximately a 4-5mm stripe. Next you need an aqueous coating with a viscosity
of approximately 18 seconds when measured with a number 3 Zahn cup or 36 seconds
with a Din 4 cup.
The next critical step is to make sure you apply kiss pressure from the chrome application
roller and the blanket cylinder and kiss pressure from the blanket to the impression
cylinder. The easiest way is verify kiss pressure is to perform a break away to
see when you have adjusted the DS and OS the same.
Remember you’re applying a coating which requires only 2 thousands squeeze compared
to printing which requires 4-6 thousands pressure. The breakaway approach also works
to reduce the hard edge of coating at the tail of the sheet and should be done with
the blanket to impression cylinder as well.

| Q: |
What is the timing for the change over for the impression cylinder to the delivery grippers on a QM 46? |
| |
| A: |
The settings requested are a factory setting. Because we don’t know if the machine is set to a true “0”, we can’t accurately give this information.

| Q: |
I have a new press operator that runs a QM46-2. He has a habit of stopping the press by opening a guard (in effect an emergency stop) instead of using the stop button. He also tries to run the press at high rates of speed in spite of trips caused by the paper not feeding correctly. This can cause the press to come to abrupt stops many times a day. He doesn't believe this does any harm to the press. My question is, does it harm the press in the short or longer term? |
| |
| A: |
While a hard stop of the press doesn’t affect short term quality of the press, there is a reason that Heidelberg along with other press manufacturers have gone to a soft stop procedure, which brings the press to a gradual stop. Keep in mind this soft stop is also used in $5,000,000 presses with gears and components multiple times stronger than a QM 46. The soft stop will ensure the longest life of the main components. The safeties incorporated on the machine are designed for the safety of the machine and of the operator. It is not recommended to use these for the general operation of the machine unless needed. I would suggest a change in daily habits.
When it comes to the paper travel and the miss feed of sheets, the machine stops quickly to prevent damage when a sheet enters the press at the wrong degree position. Nothing to worry about here.
If you continue to have sporadic feeding issues, I would recommend having a Heidelberg service technician onsite to address these issues.

| Q: |
The compressor on our QM46-2 holds air and works fine when under impression. However, if the press stops running and sits idle for a few seconds to make an adjustment, the press will not operate until the compressor kicks back on and rebuilds air. The air pressure does not appear to be leaking. It appears there may be a sensor that is not telling the compressor to kick on to keep the air at the correct pressure. |
| |
| A: |
The pressure switches S24 & S27 probably need to be adjusted or replaced.
The part numbers are:
A1.102.1551/01 – Pressure switch
A1.102.1531/01 – Sensor |

I’m having a problem setting the roller in the PU1 unit, the #1 form will not set to the plate and the #3 form will not set to the distributor roller. I have gone though the whole set up and settings as per the book but can’t get the setting right. Can you help? |
| |
| A: |
If you can no longer get one or more of the form rollers to make contact with the oscillator rollers or the plate, the rollers have shrunk and are in need of replacement. The rollers can be ordered through the Heidelberg consumables department at a discounted rate by calling toll-free 888-472-9655. |

| |
| Q: |
The delivery table on our QM46-2 continuously lowers after the first ¼” whether paper is feeding or not. What could be causing this? |
| |
| A: |
If the B1 sensor was an issue, the press would go into print suspend after 50 sheets and not continue to drop. The delivery pile lifting assembly Y17 may need to be cleaned or the shaft assembly may be worn to the point that it no longer has enough friction to hold the pile still. In that case, it may require the shaft and gear box be replaced.

I have a question about your video on running envelope. When I set up my QM46 like the video shows, the envelope jams, jumps over the stops and misses the grippers. This happens even if I adjust the sheet advance back. What can I do to fix this problem? |
| |
| A: |
The pile scanner may have excessive wear or be adjusted incorrectly. Another cause might be that the 3/2 way vale may need to be serviced or the idler rollers for the sucker bar may need to be replaced.

I am trying to run 12X18 on a Printmaster QM 46 and one corner is getting dog-eared. Do you have any idea what could be causing this? |
| |
| A: |
Usually dog earring on a Printmaster QM 46 is because of the front side blowers being set all the way down. These can get bumped when working in this area. Move the front side blowers all the way up and then about 1/16” down. Then check for positive pick up from the air blast. |

| Q: |
I have QM 46-2. My question is about the packing and meeting the right circumference. I have 8mil poly plates (.20 mm) my blanket is 1.95 mm if I pack so that I have a .10 mm squeeze I am -.10 mm under the cylinder undercut and I need to max out on the squeeze of my impression cylinder. If I over pack with a .35 mm or a .40 mm I get a nice solid but I am way over packing. Is this ok? Or what do you suggest? |
| |
| A: |
It is not a good idea to over pack the blanket to achieve a good impression between the impression and blanket cylinder to the sheet of paper. You should always pack the blanket according to the plate thickness. You need a .004" to a .006" transfer squeeze between your plate and blanket cylinder to achieve the best printable dot possible without having too much dot gain. If you do not have a good transfer between your blanket and impression cylinder after doing so then you will need a Heidelberg service tech to make a mechanical change between your impression and blanket cylinder to correct this. By over packing you may get a better solid but it will only make your screens look muddy. |

| |
| Q: |
I am having a printing position problem on our QM-46-2. When the plate is mounted and ready to print, the image on the plate and on the blanket is in the correct position. The problem lies in that when I go to print the job the image is too far forward and is cut off. I have to move the circumferential register adjustment knob for PU1 and PU2 from the 0 start position, to almost all the way from the gripper to get the whole image to print. The press is feeding and delivering correctly. What would you suggest to solve this problem? |
| |
| A: |
When you change the timing of the overall circumferential system it changes the timing of the feeder, impression cylinder and delivery together verses the printing units. This is why the paper transfers fine but may not print to your specs. It sounds like either the image is not in the correct position on the plate or that something is wrong with the timing of the impression to blanket cylinder. I would recommend having a Heidelberg service technician onsite to further diagnose the situation. |

| Q: |
What would cause head stop marks on a # 10 envelope? I adjusted the sheet arrival adjustment all the way to negative 2, but I’m but still getting 2 marks at the gripper edge.
|
| |
| A: |
Possible Causes
1. Marks on envelopes can be caused by the forwarding rollers if they are not adjusted correctly.
2. Marks on envelopes can be caused by the erratic movement of the feeder pile as it rises if the customer is not using the scanner shoe on the pile scanning lever.
3. Marks on envelopes can be caused by the transfer timing of the chain delivery grippers as the envelope may be pulled off the impression cylinder before the impression cylinder grippers have released the envelope.
Solutions
1. Correct feeder pile so that the table rises correctly.
2. Correct the angle adjustment on the sucker bar.
3. Correct forwarding rollers pressure and dwell.
4. Correct impression cylinder grippers so they close and open at correct time.
5. Correct chain delivery tension.
6. Correct chain delivery gripper bar.

Can you please answer some of my questions about a QMDI-46 Pro?
1. Should the press be in an enclosed room? (We are a Thermography shop)
2. What would be the correct temperature for the room?
3. Should the ink be taken out every night or can it be left the ink tray over night?
|
| |
| A: |
1) The press does not have to be in its own room.
2) The QMDI can operate under a wide range of pressroom conditions as long as it is as consistent as possible. If the press room is 72 degrees in the morning and in the 90’s in the afternoon, you could have printing issues.
3) You can leave the ink in the fountains overnight, but be sure to spray it with something like "Stay Open".

| Q: |
I recently purchased a used QM 46-2, so I am a new user of this press. When running the double sheet/sheet length the short sheet indicator displays. Please explain what this means, and how do I correct this problem.
I have tried to adjust air blast, suction, pile height and sheet arrival but still often see short sheet displayed. Is there something else that maybe causing this problem (mechanical)? I did not receive an owner’s manual with this press. |
| |
| A: |
Check the lens of the double sheet detector. It may have a crack or just need to be cleaned. If you would like to turn off the sheet length monitor, it is Special Function 19. This still allows the double sheet detector to work. |

| Q: |
We have a QM-46 running 12 x 18 80# Gloss Text printing 2 sides. We ran the light coverage side first, no problem. On the second side there are some solid areas and near the gripper an area that is a 30% screen. Why are suction cup marks from the sucker feet showing up in the screened area? The pressman says he has to wash the blanket every 200 sheets to get rid of the marks. What is causing it? Would using powder on the first side cause that? |
| |
| A: |
This is simply too much powder on the sheet when it went though the first time. |
| |

| |
| |
| Q: |
With paper jams at the infeed rollers on my QM 46-2, the impression cylinder receives an impression. Is this normal or should the impression cylinder disengage from the blanket cylinder? |
| |
| A: |
Any time paper feeds into the infeed rollers the infeed sensor detects that a sheet of paper is coming into the machine and at so many degrees from now the grippers need to open and the cylinders need to be locked on pressure. If a sheet is jamming at the infeed, then we would look into the sheet separation before the sheet gets to the sucker tubes. The paper stack should have the top 10-15 sheets floating on air and be guided to the non operator side of the feeder side guide and be separated with air so the sucker tubes can precisely pick up one sheet and forward it into the infeed forwarding rollers. That sheet going into the forwarding rollers should be flat across the lead edge of the sheet so it doesn’t jam into the forwarding upper and lower rollers. |
| |
Back to top |
| |
| |
| Q: |
continued... secondly, the first sheet printed after a miss-feed has at least a double impression from the blanket cylinder, the impression cylinder in this situation remained clean, is this normal as well? |
| |
| A: |
No, this is not normal. The only way a sheet can have a double image is from movement of the plate cylinder or plate. If the machine had a jam at the infeed under the infeed sheet detector, the machine should go on pressure and an image would print on the bottom cylinder and therefore giving you an image on both sides of the paper. If the paper jammed in the feeder, then the machine should stop and rollers and cylinders go off pressure before the image gets to the impression cylinder. |
| |
Back to top |
| |
| |
| Q: |
continued...and third, I have to manually predampen my Sliver master plates on start up, because if I don’t the non image areas fill in. Is this normal? |
| |
| A: |
This is normal for Silver master plates or Polyester plates. They require an excessive amount of water for the non-image area to remain open on a plate, so starting the machine and letting it stay in the predampening position for an extra 25-50 revolutions is normal and will allow the Polyester plate enough moisture to remain open in the non-image areas. |

| Q: |
We have a QM-46/2 and it wrinkles 8.5 x 11 20# white bond mostly on the gear side
of the press. I have changed stock and changed brands of stock. It does not wrinkle
NCR, 11 x 17 bond or anything else. Any help would be great.
Follow up: I discovered that the sheet arrival was or is the problem. I now
have the sheet arrival retarded (-5) as much as I can and it has solved the wrinkle
problems for now. Through, using Special Function Keys 68 it gives me 2 sets of
numbers, and they now are at: Top 321 and the Bottom 324.8. They were previously
at Top 320.0 and Bottom 323.7.I was informed that Top should be 320 and the Bottom
should be 325. That is as far as I have gotten with my problem, so far. |
| |
| A: |
The numbers are only a reference and can be manipulated and should not be used as
a true setting of the sheet arrival, only as a guide. The problem is most likely
a broken gripper spring on the impression cylinder. The reason they can run with
the sheet arrival retarded is that the sheets are not hitting the head stops of
the impression cylinder grippers and are able to lay smoother. The press probably
needs a complete gripper job.
We recommend installing new infeed wheels at this time. This is all providing that
the operator has not mechanically changed anything on the feeder timing. We would
also recommend for a mechanic to check the timing of the sheet arrival to make sure
that it is mechanically correct.

| Q: |
We have a QM 46-2. On the Second Unit looking at the dampening system, the first rubber roller that you'll see (Metering Roller) is building up ink on the right side starting at 1/2 inch. The more impression, the wider it gets. This problem start mostly in the afternoon when its warm, and never occurs in the morning. We are running two color black on the first unit and PMS 185 on the second unit. Only that that roller is building ink, as I have checked the roller behind it. In addition, when I disengage or am not printing, it distributes the ink properly. However, as soon as I engage it with water, the impression starts again in 1/2 ink build up. Can you suggest a solution? |
| |
| A: |
It sounds like there are bad roller settings due to a bearing failure. The stripes may appear okay at first, but once under pressure, the stripe may be different. It is recommended that you inspect all of the bearings in the dampening unit including the pan roller. |

| Q: |
We have been using Varn Pronto for the Blanket cleaner on our QM-46-2. Lately, we have been having trouble with this being shipped to us without excessive costs. Is there another product that can be used? |
| |
| A: |
There are shipping requirements for solutions with lower flashpoint washes. At Heidelberg Consumables, we sell only fogra approved washes. The flash point is over 142F and does not require a red shipping label. Plus, by using a fogra approved wash on the Heidelberg QM 46, you meet all of the factory recommended requirements for a blanket wash. |

| Q: |
We are experience an UV detaching pattern, and we couldn’t find the reason.
We were trying with different inks, varnish, primers and uv’s even with another paper stock but nothing happens. It seems to be some humidity trapped between the paper and the ink.
This trouble appears just when the product is on its final destination transit for more than 3 days, and with products with non cardboard covers. |
| |
| A: |
The Expert suggests that you test the substrate using a dyne pen. You can purchase these off the internet from many suppliers.
A surface tension of 38 to 40 Dynes/cm is needed for good adhesion. For anything below this value it is impossible to guarantee good adhesion. Consider returning the substrate back to supplier. |

| Q: |
I am running a Prosetter 52, Signa Station and a Printmaster 52.
Here are the specifics:
In the Signa Station software there is a place for the gripper number to be put in. Then there is a second number put in for the "baseline".
Here are the questions:
Is the baseline the distance from the edge of the plate to where the leading edge of the paper hits the plate? If not then what is it?
What is the baseline setting for the Printmaster 52? Is that constant? What would that be called in the manual as I do not see a baseline setting in the PM52 book? |
| |
| A: |
In a Heidelberg workflow there are 2 values that are used to determine what the baseline is. The press manual lists the values under "Print-related specifications" and the 2 values are:
- Distance between front edge plate and print start
- Gripper bite or Paper Bite
To determine baseline simply subtract the Gripper Bite from the print start.
PM 52 specs are:
Start of print = 58mm
Gripper = 8...10mm (variable...use mean value)
58mm Start of print
-9mm Gripper
-----
49mm Baseline |

| Q: |
My QM 46 is only allowing the center form to drop. Is there an
adjustment I missed? The adjustment screws are not moving fully against
the stops. I'm effectively printing with 1 form. This does not work with
heavy black coverage.
|
| |
| A: |
If the ink form adjustments are not moving properly, we suggest removing the rollers and cleaning them.

| Q: |
Hello, I hope you could clear my doubt, (does there) exist any "chemical free plate" for the Prosetter (violet photopolymer - silver halide). One seller told me that I could use some upgrade in the Raptor (plate procesor for photopolymer) to use this kind of plate. |
| |
| A: |
Heidelberg provided live demonstrations on the new Saphira Violet Chemfree plate at the recent drupa tradeshow. The plates ran through a new compact cleanout unit that did not have developer or water sections since they are not needed. This cleanout unit takes up less space and uses less energy as compared to a traditional processor. The schedule to release the new plate and cleanout unit is Q1 - 2009. As for converting your existing processor, we do not yet know if this will be possible. Please consult your local Heidelberg organization when you’re ready to convert and they can give you the latest status on this. |

| Q: |
What is the correct way to set the intermediate roller on the SM-74? When I use the method described in the operator’s manual the dampener does not wash up.
|
| |
| A: |
You need to make sure the Intermediate roller is set properly to the #1 ink form. Checking the ink stripe (3mm) of the intermediate roller to the #1 ink form roller:
1) Make sure that that integration of the dampener is selected on at the console.
2) Ensure that the ink form rollers and the water form are in contact to the plate .
3) The gap of the plate cylinder should face out away from the rollers.
4) Inch the press backwards to see the contact stripe between the rollers.
5) The adjustment is the spring rod with the 13 mm nut. Make the adjustment and try again.
6) If the #1 ink form roller has shrunk too far you will need to replace it.
7) Make sure that all pneumatic pistons are working properly.

| Q: |
I am having a problem with our IR dryer on the
PM46-2. The press was installed in January of this year, but with a move of our
business in the near future, we did not run power for the IR dryer. We are now in
our new location and have the IR dryer powered up. The problem is, sometimes it
works and sometimes it doesn't. The press goes on impression and the IR dryer doesn't
fire. The temp is set for 97.5, and the read out for actual temp is low (70's to
80's). It will be working just fine and then next time I start up - nothing. One
odd behavior during its malfunction is that it will fire for a second or two (like
when you first turn the unit on for operation) when coming OFF impression at the
end of the run, or interruption with the production button. Any ideas?
|
| |
| A: |
A common cause for the IR lamps to shut off unexpectedly is a mal-adjustment of the Baumer Jam detect
sensor. Please refer to the sensor adjustment procedures for proper adjustment. NOTE: If you are repeatedly having to
re-adjust the sensor, try turning the sensitivity screw counter clockwise a little more AS THE LAST STEP. A sensor
adjusted too close to the edge of the yellow light going on and off could be troublesome, as the tolerance on components
in the sensor may relax a little over time.
Please refer to the attachments for easy reference.

I have a QM DI-46 and some of my ink keys are out of adjustment. When
I zero out a tray some of the keys do not close fully, and some do
not open evenly when I set the keys. How can I adjust this problem? |
| |
| A: |
Remove the cover that surrounds the ink key levers by removing the two 2.5mm Allen head bolts located under the ink fountain.
You will see the adjustment Allen head bolts (4mm) next to each ink zone lever.
With ink in the fountain and all of the levers in the same position you can adjust the keys. |

| Q: |
Our QM46-2 Is having a few problems, just thought you might be able to help us out. When running a job and using PU2 we find a strip of 'catch up' running the length of the sheet near the operator side.
I have included a photo with this so you can see what i'm talking about. It appears in intervals of 500 sheets, when I use the blanket wash it's gone then 500 sheets later it will re-appear.
The dampeners are as close to off as possible, we have increased them but that just floods the plate etc. |
| |
| A: |
The first thing that I would have you try is to adjust all of the form rollers and pay close attention to the dampening form roller. If the settings are okay, it may be time to look into replacing rollers. |

| Q: |
I'm having a problem with my QM 46 not getting much spray powder.
I have cleaned the lines, checked all connections and the solenoid is working.
How much air should I get from the Gast pump?
It is 3 1/2 years old; what is life of this pump?
|
| |
| A: |
The pump does not usually fail; most of the time if you notice loss of spray powder control there is a clog somewhere in the system. The sprayers in the powder housing sometimes can block the powder from spraying properly, or the manifold could be clogged.
There is a quick disconnect on the black powder line. I would recommend disconnecting the powder line there and test the system with special function 04 using the plus and minus buttons. If the spray comes out ok then the manifold is ok and a clog is further down the line. If the spray is weak then the manifold needs to be cleaned or possibly replaced. The only thing on the pump that should be checked is that the paper filter is not clogged, restricting the airflow.
For detailed information on the pump itself I would recommend contacting Airtech; their number is located on the side of the powder system. They will require the model and serial number which is also located on the side of the powder unit.
If you are not comfortable with these suggestions, please contact Heidelberg support.

| Q: |
We have a QM DI 46 Classic and are having a problem with a quarter inch roller stripe showing up on the black image. We have adjusted all the rollers and can't see anything wrong. What is causing this problem? |
| |
| A: |
The mark could be due to a variety of causes, such as: the roller hangers may be worn, or cylinder bearing wear issues, or bearer pressure adjustment issues.
I suggest first that (in this exact sequence) you remove the 2nd 3rd & 4th transfer rollers; then adjust forms (2/1/3) to distributors. Then adjust forms (2/1/3) to the plate, then install the 2nd 3rd &4th transfer rollers and adjust them with the forms dropped on the plate.
Now re-check the forms to the plate and if you notice that the forms adjustment to the plate have changed (and usually the 2nd form will be the most noticeable) this would indicate that the roller hangers are in need of repair.

I have a Speedmaster SM 74 with IR dryer. What temperature is recommended?
Also would it be different for QM 46? We use a 22 micron spray powder.
|
| |
| A: |
Try starting at a point between 90 and 105 degrees depending on how thick the paper is. There are several variables but that is a good starting point. It is the same with QM 46.

| Q: |
I am dealing with sheet mis-registration and I believe it is caused by static. I spoke with a tech the other day and he recommended using Bounce on the feed board. Is this the best option? Where should I place the Bounce strips on the feed board? |
| |
| A: |
Depending on the press you have, you can tape fabric softener sheets to the feed board tail edge only. The printed sheets will then pass over the softener sheets, releasing the antistatic properties. However, you must be careful it does not cause mis-registration. The sheet should be fixed as far from the head stops as possible. |

| Q: |
We have a Printmaster 52 2 colors and also a SM 52 two colors, we are looking for a CTP system, but want to know the advantages between the Quicksetter 400 and the Prosetter 52. |
| |
| A: |
The Quicksetter 400E is a CtP designed for the GTO 52 format. The PM 52 and SM 52 are larger plates sizes. The Prosetter P52 is a perfect fit for the PM 52 and SM 52. The Quicksetter is a polyester plate CtP device that is rated up to 175 line with run lengths of up to 20,000, whereas the Prosetter P52 is a very high quality, metal plate CtP rated up to 300 lines per inch, Hybrid and FM screening-capable and up to 350,000 run lengths. The Prosetter P52 can have internal punches, is the only violet CtP with Temperature Compensation, can be upgrade to various levels of automation and even to a larger 4 up format, the Prosetter P74. |

| Q: |
When running my QM 46-1 the water bottle locks up and the water pan goes dry. What is causing this annoying problem? |
| |
| A: |
The reason for your problem is most likely that the valve does not open up completely and does not allow the water to flow correctly.
We would recommend a new water bottle cap; they can wear out after a while. |

| Q: |
On a 1996 Polar 66 trimmer. Recently I have been getting a "Knife at BDC, time interrupted" message on every cut. Through the years I have noticed that the knob for knife changing has lost some resistance. As a result it would eventually drift from the far clockwise position and I would get the same message as above, turn the knob back and it was fine. Now it's constant.
Is something worn in this valve? Hydraulic fluids are full with no leaks. |
| |
| A: |
The message “484 Knife at BDC Time interrupted” means that the knife was released to move to the up position before the bottom dead center switch was met. This can happen from releasing the cut buttons too soon as well as having the knife go too deep into the cut stick. It should have nothing to do with the valve for knife change. The valve for knife change will keep the knife from TDC or top dead center.
Please contact our technical help desk at 800.437.7388 if you should have additional questions. |

| Q: |
I have an SM 52 A3 four colour machine and a GTO Z two colour and a GTO one colour machine. Is there a UV coating component or accessories that can be added to any of these machines to do UV printing? |
| |
| A: |
All presses that are used for UV printing have to be factory prepared (in printing units, coating units and delivery) to withstand the more aggressive press chemistry that usually goes along with the UV printing process. The UV preparation can only be done practically in the factory when you order the press – it includes UV rollers, UV conform grippers, special prep for wash-up devices etc. If your presses are not factory UV prepared they are not approved for inline UV printing.
Both the Printmaster GTO 52 and the Speedmaster SM 52 presses can be UV prepared - and then be used for inline UV printing. However, a Heidelberg coating unit for UV is only available for the SM 52. Curing solutions for the UV dryers are available 3rd party manufacturers. |

| Q: |
I am having trouble with ink "piling" on the water metering rollers on a GTO-5 with DDS dampening, is this an ink/fountain solution issue or a roller adjustment? |
| |
| A: |
Ink piling is normally an ink/dampening solution issue, where the ink is not able to withstand the strength of the fountain solution, either due to the mixture ratio or the type of solution altogether.
If it is the same solution you run normally, you most likely have a contamination issue that can be taken care of by washing the press with HOT WATER AND WHITE VINEGAR, (do not use a chemical deglaze or the like, as it is very hard on the rollers). The hot water will chase out the water based contaminates and the vinegar will chase the mineral deposits out of the rollers.
It may be necessary to do this several times to get the problem to go away, and it should be done on a weekly basis afterwards to prevent further contamination problems. |

| Q: |
I am running an old MO-4VP at a university in house.
At this time of year like everyone we fight with fan out on any size sheet of text and offset. The question I have is if there is anything other than sealing every nook and cranny in the building to prevent this? They use two dedicated a/c, heating and humidifying/dehumidifying units, but they seem to do little to help this problem.
Any advice would be welcome. |
| |
| A: |
Yes, paper conditioning is the issue, but some additional questions are relevant: how old is the paper, when was it delivered, was it cut down at the correct grain If the paper was cut and not covered with plastic to keep in the moisture it will shrink and then stretch when printed, and unit 1&2 may not fit.
If the print jobs are not covered after printing and the backup does not fit it may be due to running the dryer too high causing the sheet to shrink after drying.
In any case, the paper should always be covered this time of year to prevent dehydration. The paper companies will normally provide plastic load covers to help prevent this between passes, especially if it is overnight between passes. |

| Q: |
We have just recently purchased a Heidelberg Quicksetter and need to know how to send spot colors {2/C} to the Quicksetter.
We are set up from installation to send 4/color, 1/color, and positives for silkscreen. Jobs we are trying to send as spot color are in pdf and we are using Dell PC |
| |
| A: |
In order to print a two-color job there are two important steps that need to be followed when creating a PDF file.
All the colors in the job must be defined as the desired spot colors. This is done in the application the job is being created in (such as Quark or InDesign). The PS or PDF file should be output using the In-RIP Separations or Device N settings from the application (Quark or In Design). Once you have a properly created a PDF file the RIP will be able to separate it to the correct colors/separations.
A properly created PDF file (with 2 colors) will open in Acrobat as a composite file. In this format the on screen view will look like the final printed piece.
In Acrobat 8 you can see a preview of the separations by clicking the Advanced>Print Production>Output Preview menu. Here you can see the colors in the job and select/deselect colors to preview it.

| Q: |
I have a PM 52 with Alcolor. We installed new rollers, and seem to be having a lot of water problems: is running too dry down the center of the plate.
Also, the intermediate roller does not want to carry ink. We have set ALL rollers to SPECS. Any suggestions?
|
| |
| A: |
Check to see if the rollers are the same type that were in the press previously – i.e. alcohol free, or crowned for alcohol?
It sounds as if you have crowned rollers which are meant for alcohol, and you are running alcohol free. If you re-install the old rollers, does the press run better?
I suggest you check with who you purchased the rollers from, find out what type roller you were sold and that it is the correct roller for your application.

I have a Quickmaster 46-1. I am getting scratching marks down the plate that I can't seem to stop. I have checked the water form roller and found the bearings were collapsing and replaced them, but I am still having a problem. What do you suggest? |
| |
| A: |
Depending on the age of the machine, plate scratches might be caused by two things, the plate processor or the plate loading guides on the press.
Please check the plate guides on the press as well as the guides in the processor for sharp edges or build-up. In extreme cases worn guides with sharp edges might leave scratches. |

I have heard about SF 22 which I'm informed will clean both the blanket and the impression cylinder, is this correct? On our press this seems to do nothing.
Is there a listing of all the SF numbers? |

| Q: |
How tight should the chain be on this press (QM 46-2)?
When I inch the press around, the gripper bars are hitting the screws that hold the blowdown fans on. I'm not sure if they are hitting when the press is at speed, but there is a lot of noise and movement in the chain when running.
Which way do the adjustment bolts get turned to tighten the chain. None of this is covered in the manual.
|
| |
| A: |
The chains on the P-QM 46 are self-adjusting. If the chains are making contact they need to be replaced.

| Q: |
I am running a QM DI Pro. I noticed over the last year I have been printing with an orange peel look on my 1st unit (black). I have to put lots of pressure to reduce the blochy look of the images. Normally I run at about a 0.05 or 0.06 on my pressure dial but now have to run at 0
to make images smooth. What is up?
|
| |
| A: |
There can be various reasons for your problem. Here a couple of suggestions:
• Check the temperature of your chiller. It might be set too cold (should be between 18-20 degree Celsius)
• Check the age of your rollers. They need to be replaced on a regular basis
• Check your roller settings - they should be as recommended in the operator manual
• The ink chemistry might have changed - check with your ink manufacturer
• Check the age and the packing of your blankets - they should be as recommended in the operator manual.

| Q: |
I do not own a Heidelberg QM-46 Press. My major concern is the type of register control. Could you explain the type used on this small offset? |
| |
| A: |
The Printmaster QM 46-2 has on the fly adjustments for lateral and circumferential register settings (see pictures) in both units (you can make these adjustments while the press is running).
The diagonal register setting is done via a special function that positions the plate cylinder and loosens the plate. The adjustments is made in “clicks” with a provided multi purpose wrench – again a very fast adjustment.

| Q: |
I’ve just purchased a (Heidelberg) Printmaster QM-46 and am running 12"x18" 100# text dull coated.
PMS 128 (yellow) and black. Front 1/3 of sheet is solid yellow with black type on top. I put yellow in Unit 2 (nearest Feeder) and Black in Unit 1.
The yellow is becoming contaminated from the black ink and the tacks are even and long (Zipset Inks).
I have washed the yellow rollers thoroughly. The press run is 7,000 work and turn. Using 8 mil. polyester plates.
I fault the single blanket. Any advice? |
| |
| A: |
From the description is appears that the problem is caused by the ink tack.
When running any combination of color the light ink MUST be at least 1 tack point lower than the darker ink, this way the light ink will not pull the darker ink back onto itself.
In the description it is indicated that unitack inks are used; this really only works in unitized machines, and even then the large majority of printers still use staggered tacks in their process and over print situations.
With the common blanket it is important to use tack-rated inks; best results are usually achieved with the following approximate tack values: yellow 12-13, Red 14-15, blue 16-17, Black 18-19.
We have seen runs as high as 10,000 sheets running Black and Yellow with no back trap contamination using the method above.
Note to readers: In the original answer above, we focused exclusively on the topic of ink tacks, which is usually the main issue at hand. However, we didn't discuss which color to put into which unit. A sharp reader brought this to our attention (thanks Lance) so to the answer above, we add our recommended ink allocation:
Light color, low tack in Printing Unit 1 (above the delivery)
Dark color, high tack in Printing Unit 2 (above the feeder) |

| Q: |
I'm thinking of changing from metal plates to 8mil Silver Digi-Plates. Will the Printmaster 46 automatically load and eject these 8 mil polyester plates? Is there any reason to be concerned about tight registration (and trapping) between the main and second color head when using these plates? |
| |
| A: |
8 mil plates work very well in the PM 46. You will have to adjust the blanket packing and reset the rollers to accommodate the thicker plates. Also, be aware of different settings for the dampening system. You might also see an increase in the amount of make-ready sheets.
Make sure you are using the plates with the matte back, as that minimizes the plate movement. Heidelberg also provides an 8 mil Polyester plate material called the Cristala Quickplate; if interested, please contact us at 1-888-472-9655.

| Q: |
We have a QM 46-2, and tried on the odd occasion to print
4 color process runs, with relatively pleasing results; however we found a few issues. First we could only use an A4 sheet size, long edge into the grip. We had to use a 200 gsm board, and the register did move slightly. We were wondering, apart from the tips .pdf you have published, if there was any more information you could pass on, ie. what paper weights run the best for 4 color work? Do you have the pile pressed fully against the spring or slightly touching to keep a tight register throughout out the length of the run?
|
| |
| A: |
Not knowing the serial number and the total impressions on the machine, I will go on the premise that the machine is in average condition.
To obtain the best possible results when running 4 color process jobs on the QM 46 start with good quality paper running long grain (I would recommend 80 & 100 lb text weight minimum). This will help eliminate register problems in the tail corners (fan out). Also, if you have an IR dryer use it at approx 70% on the first pass to prevent paper shrinkage during drying, then at 90-95% on the final pass.
If the job is two-sided, run all four colors on one side before running the back side, otherwise you will have fit issues on medium-to-long runs. It is also recommended that the loads be covered with plastic if the second pass of the four color will not be run on the same day. This will help keep the moisture in the paper, which helps with fit on the second pass. The paper company's have load bags they provide to large printers for very long runs, or a small shop can use an ordinary trash bag to achieve the same result.
When setting up the feeder, always make sure the paper is firmly held to the front and side standards, and test to be sure it will feed consistently before you start the run. Once you have verified that the job is in fit and is registering to your satisfaction, DO NOT CHANGE IT DURING THE RUN. This will help to insure consistent register throughout the run.

| Q: |
Is there an automated way to read ink dots and automatically adjust the ink keys? |
| |
| A: |
Most prepress RIPs have the capability of generating what is called a PPF (Print Production Format) file. It is commonly referred to as a "CIP3 file." This is a file that is used to generate ink-key presets on a press and is based on the same data that is used to generate proofs and plates (or film). The PPF must be processed through an intermediate application before being sent to the press for presetting the ink keys, which analyses the ink coverage, per color and per ink zone, and calculates the physical ink key openings, which are then provided to the press. The press interprets this information and applies it automatically. The PPF can be transferred to the press either by a job memory card or directly to the press if the press is networked. The press must have remote ink control capability in order for this to work.
Most press manufacturers build the ability to read the presetting data into their presses, and sell the intermediate software that interprets the PPF. The software is usually proprietary to the press. The Heidelberg interpretation software is called Prinect Prepress Interface. Systems from Heidelberg that are capable of performing the presetting function for Speedmaster and suitably equipped Printmaster presses:
Delta RIP with CIP3 option (past generation Heidelberg RIP)
Prinect MetaDimension with CIP4 option (current generation Heidelberg RIP)

| Q: |
We have a QM-46-2 and we’re running a 2 color letterhead on 70# Finch Fine Text.
The copy is washing out like there’s too much water. We can get it to print half decent but have to run the press at 5000/hr.
If we switch the paper to almost anything else including glossy the problem goes away.
The pressman says the water roller pressure is as tight as it goes.
Do you have any suggestions? |
| |
| A: |
This sounds like a problem of chemical contamination in the paper.
As a test try this:
- Run approximately 100 sheets of the paper through the press on
impression only, (no ink or water)
- Wash your blanket and plate (if there was one on the press).
- Run the same sheets through the press normally to see if the results change.
I think you will see an improvement.
Running the paper through on impression only will help remove whatever it is on the sheet surface causing the problem. |

| Q: |
I have a 1996 Quickmaster 46-2 color. After running the 2nd unit and washing up, when going into my next job and putting the press into the production mode on the OS of the 2nd unit I have no dampener contact on the last 4 inches on my plate on the OS. I have to adjust the red screw clockwise to print clean. Is this a bad setting or a worn part? Also, both water units rock in sync with the oscillating roller - is this normal?
|
| |
| A: |
You may have to adjust your plate. This adjustment is done by means of the adjustment screws on the ends of the form roller shaft, not the Red Screw. *The Red Screw adjusts the pressure between the form and the pan roller (3mm stripe).
Items to look for if the adjustment to the plate cannot be achieved by means of the screw on the shaft:
- Problem - The cams on the control shaft could be worn or loose
Solution - Check for wear and the screw for tightness
- Problem - The pins at the bottom of the water system frames could be worn or not adjusted
Solution - The adjustment screw should be flush with frame
- Problem - The compression springs in water system frames are worn
Solution - Pull the adjustment screws to check springs and replace as needed
- Problem - Frames are loose and wobbling excessively (worn bearing journals)
Solution - You might need a new water system cpl.
- Problem - Form roller worn
Solution - Swap the ends to see if problem goes to opposite side
Please note: The roller cannot be used this way because of the position of the adjustment screws to stops
* The RED screw is an adjustment screw used in setting the control stripe 3.1mm of the Dampening form roller MV.028.411 /09 to the Water pan roller MV.039.427 /02. It is possible that the self locking Helicoil is fatigued and allows free movement of the RED screw and loss of adjustment. Replacement of Helicoil required HDM: Part number 00.580.2707/ Threaded insert magazine M6x0, 75x 9 and can be ordered thru Heidelberg spare parts. As this insert requires special tools to insert, you would need to contact www.alcoafasteningsystems.com and request the following tool, part number # 50188.
Additionally, it would also be possible that you are experiencing bearing fatigue of dampening rollers. Please check and inspect for damage and or wear of all bearings of the Dampening system.
This answer is our response based on your input. If you have any concern on how to safely make any of these adjustments or to investigate the problem further, please contact Heidelberg systemservice 1-800-437-7388. |

| Q: |
I have Version 1.5.5 (Build 613.1) Medium format, PDF handler 2.77
Imagine the following:
4 pages of 8 1/2 by 11 (Automatic platement rule), Saddlestich binding.
Plate: SM 74, Work and Turn, sheetsize 25 by 19
Scheme: F04-01_ui_2x1, expert mode check odd columns (head-to-head)
File->save
Now, rotate page one using this method:
In the Press Sheet view, double click page one (folding sheet inspector) and double clock page one AGAIN (Page Inspector) . In placement rule for 1up, choose By user, from trim, 180.
Go back to Press Sheet view and confirm page one is rotated.
File->save
I want the rotated page to stay rotated, in other words I want it to "stick" no matter what else I do.
Bring up Job Part Instector (control-2), click on schemes, Gaps and master pages, and change something, say the vertical gutter by typing in a new number.
Naturally you see the warning you are about to change a setting that another inspector has set, but click on yes.
Notice that page one has rotated itself back to its default orientation.
Is there any way to rotate the page, and make it stick?
|
| |
| A: |
In Imposition mode, Signa Station will automatically adjust back to the original folding scheme if a page is rotated. Use Montage mode to avoid this behavior. |

| Q: |
Why is it that Heidelberg DI presses are not sold anymore? |
| |
| A: |
Heidelberg USA continues to sell Quickmaster DI presses. The majority of these presses are refurbished presses. The refurbished DI presses offer an affordable and easy entry into the four color short run market. Heidelberg USA continues to support all existing Quickmaster DI users with parts, service, consumables (plates, blankets etc.), RIP upgrades as well as phone support for print technical questions and workflow questions.
Heidelberg stopped manufacturing new QM DI presses because the worldwide demand for new small format presses shifted towards landscape presses with more flexible configurations (e.g. 5th color, inline coating, inline perfecting). At the same time the advent of small format CtP systems, attractive CtP-plate pricing, greater press automation and overall higher productivity changed some of the underlying assumptions that made the new QM DI presses a great success in earlier years.

| Q: |
I have a GTO Z-52. Can a coating unit be put on this press? |
| |
| A: |
There is a Heidelberg approved roll-on coating unit available. It is manufactured by the German company LACO.
There are some prerequisites for the press for this to work with the LACO unit.
It must have the "Plus" drive - also called the "basic equipment for numbering and imprinting," which can't be retrofitted to an existing press.
The "Plus" drive is necessary to drive the coating unit during the production run.
Also, the interface adapter for peripheral devices (STA unit) is required - if necessary, this part can be retrofitted to an existing press.
Once installed, the LACO coating unit requires an air-cooled dryer - usually these two components are sold and installed together.
Check the LACO website for images and more details: www.laco-bruchsal.de |

| Q: |
I seem to be going through a lot of wash up blades on my GTO 52, about
1 each unit every 2 months. Is there a fix for this? |
| |
| A: |
There are two reasons that wash up blades wear quickly, the
first is that they are set too tight against the oscillating roller and the second
is allowing the blade to remain on the roller too long at the end of the wash up.
When setting the wash up blade, the operator needs to set the blade (on models with
manual adjusting screws) just light enough to remove the ink and no more.
On models newer than Drupa 2000, the operator should check the adjustment of the
stop screw on the operator and drive side for proper adjustment, (see drawing below)
so that when the wash up unit is engaged it make just enough contact to remove the
ink.

| Q: |
Do you need to run different Ink Tacks when running a two color job? |
| |
| A: |
Yes and No…… No, because if the colors on the job are not
touching, then the ink tacks can be the same. Yes if you are wet trapping; then
you need different ink tacks so they trap properly on the sheet of paper. |

| Q: |
Is there any way to keep the polyester plate from stretching? |
| |
| A: |
Yes. You can turn the plate over on the back side, and use
500 grit wet and dry automotive type sandpaper to scratch the back side of the plate
at a 45 degree angle to the lead edge of the plate, in both directions. Then wet
the back side of the plate and load it on the cylinder……The scratches will provide
pockets of air and water and cause the plate to stick to the cylinder. The only
downside is that the plate will have to be taken off by hand because it sticks so
well to the cylinder. |

| Q: |
If you add ink reducer to ink, will it change the color? |
| |
| A: |
Yes. Ink chemists have formulated the ink with the correct
ratios of ink pigment (color), vehicle (carrying agent), and additives for drying
of the ink, so if you add anything to the ink it will weaken the strength of the
other two categories, causing the ink to be light in film strength. Talk to your
ink manufacture to make changes to your ink; their chemists have much more knowledge
about the make up of the ink and can provide you with a solution for your needs. |

| Q: |
I'm getting a tone down the side of the printed sheet. What could
be the cause? |
| |
| A: |
There could be many reasons for this condition. The first
to check are the roller adjustments in the ink train, you could have swelled rollers.
The second would be to check the dampening system for adjustment, where perhaps
the water system is only working on one side or the other. The third would be to
check rollers to make sure they have enough ink on them to carry the water to the
plate and the ink is not emulsified. There are many reasons that a tone or scum
happens on a plate. |

| Q: |
How do you print 4 color on a standard #10 envelope? |
| |
| A: |
Most printers would print the 4 color job on the flat sheet
first and then convert the envelope to a # 10 envelope. Check with your envelope
house and they can give you the format to follow to print the flat sheets. |
