Dear all, We have recently been given access to an abrasion tester (A taber abraser machine) that we would like to start using for recording rub resistance of our sheetfed inks and for when we trial new ones. Do any of you have experience with this? I am trying to find out what a...

A question to my fellow sheetfed operators out there: Does your powder system have a noticeable effect on your sheets? Our powder unit does not appear to have much impact on the process, and never has. Currently, whether we run it 100% or 10%, there seems to be little to no difference. We...

Dear all, I'm looking for a conversion sheet, or at least a formula, and I was hoping one of you might have it. - Need to convert viscosity readings from a Zahn 4 to a Zahn 3 cup. (I have a recommended viscosity with a Zahn 4 but need to convert it to a 3). - Need to know how much...

Dear printplanneters, We have a job that we only print once a year, a 4 color cover that is a solid brown. It is close to a 7504 brown if you had to put it in pantone... We get horizontal streaking (parallel to cylinders) consistently in the same place every time we print this...

Hello all, We are running in to some troubles with our Printmaster QM46-2. We keep getting feeder trips even though we run an envelope feeder. We have pretty much ruled out envelope feeder problems and are now troubleshooting the infeed on the press. Currently using #10...

Hi all, Was wondering if any of you have used Nicoat Aqueous Coatings as an AQ? We are looking in to testing some different brands of AQ and was wondering if any of you had any comments on Nicoat (or any other AQ you really like). We are mainly looking for protection of the...

Dear all, We are getting problems with set-off and would like to see if any of you have suggestions: Press: Komori Lithrone 28 Problem: We print 2 passes on cover material, a 210gsm paper. One side of the paper is a coated surface, the other side is uncoated. We first run the...

Hi all, Currently we run two sided print on cover material. The "Cover" is a gloss type paper and the back side of the cover is an uncoated paper. When we run these stacks of covers through lamination, we get setoff from the uncoated backside (the pressure roller pushing the sheets...

Hi all, Currently we are getting some coating build up on the tail edge of the sheet (in the spot where the packing drops off) on our Lithrone 28 with 3 roller Komori Coater (Steel pan roller, rubber metering and steel aplicator roller). This isn't usually a problem, but we have a...

Having a problem with our Magnus VLF with continuous feed not reaching the pins on the leading edge when it is getting loaded on to the drum. The plate picks just fine, but when it is being moved on to the drum, I can see that it is not going in to the clamps all the way. We keep getting the...

Hello all, I was wondering if any of you had the chance to use the "CLEAN INK TRAY" fountain liners for sheetfed. It is a foil they make that sticks on to your ink fountain that way you dont have to go through as much cleaning during a color change. We are looking in to trialing...

Hi, On our Print console for our Magnus VLF MCU, when we reload a cassette, is there anyway to have it automatically reset the cassette quantity? We can manually put in how many plates we loaded during a break in the action, but I seem to remember it being able to update that as soon as...

Machine: Lithrone 28 Problem Description: Getting what appears to be oil spots on the sheet. Already did the usual thorough cleaning, checked the bearers for flinging oil, checked blanket wash cloths to make sure no rubbing. This is not a problem that is all the time and not always on the same...

Dear all, Any of you have experience with 14pt board, glossy on both sides? We can't seem to run this stuff consistently, the sheets keep sticking together, giving us double sheet. We cant add enough compensation with fingers, air blasters, etc... Tried all of the normal...

Hello, I was wondering if any of you could explain in simple terms what exactly the M values are on a Komori Lithrone 28 and what exactly they do, and how they differ from the Ratio? Thanks in advance for posting

Dear Printplaneters I was wondering if any of you have ever seen the chrome plating come off of a dampening system roller? If so, do you know what caused it? Thanks for any time taken to post!

Was wondering if anyone had any experience with the Spectro Jet scanning spectro? We are going to be installing several of these soon and I was wondering if anyone had any "need to know" things about them. Thanks

I appreciate any input you all might have on this: We might be changing our brand of printing plates in the near future. We use a CTP process for our lithographic plates. Our management wants to know: what are the standards for a printing plate? What should a printing plate be expected to do...
