Method for controlling dampening solution in lithographic offset printing machine, involves detaching set of roller segments in zones with increased dampening solution requirement from roller

摘要

The method involves engaging a set of roller segments in zones with reduced dampening solution requirement to a roller. Another set of roller segments in zones with increased dampening solution requirement are detached from the roller. The roller is different from an ink duct roller (15), where segment rollers (11a-11f) lie at the roller. The roller segments are provided with breadth that corresponds to breadth of the respective zones, and are adjustable to each other. One of the segment rollers is arranged at a color deck roller.
