Hand stack (wind up)a skid of paper and see if you have the same problem! If it clears up my guess would be static, Something you might want to try is letting the paper climatize in the work area providing you have some sort of climate control.

you could always use multiple passes thru the press and dry trap if you run into color rotation problems. It is more time consuming so you run into a turn around time versus quality issue...

After you get the big chunks out run a little varnish through the rollers and watch what paper is left come on out.. This works pretty well for me...Thank God it isnt often

Deintegrate your water rollers from the ink train! And start with thinner ink film! are you running the metalic down 1st or last? Are you over printing the metalic?

Once again this group has performed to the highest standards. I thank you all.

There should be a working communicatiion between the CSR's and the pressroom on such problem jobs, A good CSR should be able to identify a possible problem such as heavy coverage and offset. So there can be any ajustments in pricing if needed. But at the end of the day its the pressroom that...

All I can say is " I feel your pain".. been there. and as frustrating as it is you have to keep on plugging away! And dont ever expect purchesing or sales to listen to you.

Seems like this is a regular Heidi issue! I also run an older model speedmaster 102 and we get the same problems as you mention. When we have tight register such as knockouts and 1 unit is printing longer than the others we will add packing to the plate. (We do not have to do this on all jobs)...

Im new to this Stacato style screening and just wondering if this is a new direction the industry is moving as a standard? Also thanks to those that have posted articles on this style of screening. I am a pressman by trade and would hate to be slammed on press with this one day and not know...

We done a couple of jobs with ink ductor water based coatings. The spray retarder helps some on short stops but clean up when the job is done is time consuming. Recomend you find press with coater unit.

We are running Heidelberg speedmaster 102 W/Aq coater no perfector

thanks for the feedback. Can anyone give me an estimated price on this PPP system? Also you said you used your coating unit. does it if a single BC or double BC. I was thinking of doing this on our coater unit even though it has a double sided BC . I would rather run the perf on a non print unit.

If your running into static problems on the feed board try mounting an uncoated stock or piece of paper packing on the feed table under the belts to cover the metal parts. This has helped out alot on our larger presses.

Always keep a back up plan available. We work in a climate controled room and still get issues. Especialy when paper arrives same day as printing takes place. If your having static issues: antistatic spray, or tinsel works ok, but rehandeling the skid works best.

Temperatures may be causing your foam as well. 55 to 60 degrees works best for us.

Here is the set-up. 4/4 with spot varnish and perf. Is there any problems that might arise perfing inline on the spot varnishing unit on the second pass? This would be a long run maybe a couple of hundred thousand! 80# matte stock. Any key things to look for before any problems might arise...

Strickly hand washing here. Heidelbergs roller and blade systems on older press had problem dripping solvents onto cam followers...

Ah! it is kind of comforting to see that we are not the only ones that are having problems with feeder people. I know I have had my share of feeders that couldnt even rember thier name from one day to the next. Maybe that is why there is a pressman baldness problem. Makes you wanna pull your...

Trim about a 1/4 inch of your insulation off the top of the back side of the water pan this should give you more clearance between grain roller and pan. Or you can re-insulate your pan with a thinner insulation. We have had the same problem before as well but no more.

If your looking for maximum reflectivness out of your varnish on the dark uncoated sheet sounds like you may want to Dull AQ the sheet first and applie spot varnish on second pass. The Idea 67Drake has sounds good too with adding the 1%-2% silver. I might try this just to see what happens.. We...
