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 into the main drum on the laminator). Any of you have any experience with this problem?
-We have tried changing different powder types for the uncoated, using an AQ on the backsides, and even letting the sheets sit several days before laminating. Also, waters on press were reduced to bare minimums. We have had this trouble with several different brands of ink, so it is not just limited to a certain ink type.
Anything else you might think of? Any feedback is greatly appreciated. Thanks,
K
