Are ink worms eating away quality?
April 1, 2008

 

Question: We are having what I feel is a serious in problem. We have tried four ink company’s inks to no avail. I have sent to you some sheets and await your reply. What we see are irregular lines that seem to occur primarily in solids and with heavy builds. This seems to happen after the job comes off press since the pressmen say they never see them when they pull sheets.

Answer: I have seen this problem just a few times. When I examine the sheets with a 30× and a 100× scope, I can see rather precise definition to the irregular lines. After examining about 100 defects, which look like a piece of string laid on the sheet when wet, I can come to a conclusion: You have ink worms in your pressroom. As I stated above, this is a rare problem. Careful cleaning of the pressroom and not allowing any food in the pressroom will solve the problem.

By the way, happy April Fools' Day!
