Printing machine's register presetting method for multicolor printing, involves determining control value for drives and motors from distance of plate from stoppers, and providing distance compensated in one initial position based on value

摘要

The method involves providing printing plate cylinders (1) with drives (9, 10) and motors (11, 12) in an initial position, before beginning a printing process. A printing plate (13) clamped to each cylinder is brought to an edge against stoppers (18, 19), where distance of the plate from the stoppers is measured after operating a clamping and holding device (20), distance sensors (21, 22) and a control device (23). A control value for the drives and motors is determined from the distance, and the distance compensated in another initial position is provided by the cylinders based on the value.
