Film Gravure Dirty-gravure Cylinder Making Oct 12, 2016

Cause analysis of (1) if the gravure cylinder plating chrome layer hardness does not meet minimum requirements, in the so, intaglio roller surface non-graphic zone is easy with excessive wear caused by friction between the blade and wear region will be immersed in ink, which transferred to the film dirty failures. (2) if the gravure cylinder chrome polishing is not sufficient, would lead to CR plating layer surface roughness, the machine will use dirty failures. (3) the gravure cylinder plate flaws, can result in black marks on residue, resulting in dirty failures.
