Ink removal method for printing press

Abstract

An ink removal method for a printing press includes an ink removal step of bringing ink form rollers and a dampening form roller into a throw-on state relative to a plate cylinder, and bringing the dampening form roller into a throw-off state relative to a ductor roller of a dampening unit. The ink removal method has high general purpose properties, and can remove ink from the dampening form roller with high accuracy by simple means, i.e., changing throw-on and throw-off timings for existing rollers without using a rider roller or the like.
