Abstract

A piece of coating color or base paper picked during printing is called coating pick. Loosely bonded materials of coating color or broken piece of fiber could be adhered to the blanket or would be mixed with ink during printing. Because the coating pick can make troubles in printing press such as piling, hickey and collecting, the coating pick of a paper has been one of the most serious problems in printing. In this paper, two influential factors to the coating pick in the printing, those are latex content and ash content of the coating color, are studied. The surface resistance of coating paper is directly proportional to the latex content, otherwise inversely proportional to the ash content. We propose a different way to evaluate the picking and used a homemade pick test device.
