Abstract
Device and method for the automatic register setting of printings printed by plate cylinders in a rotary machine using inks of a plurality of colors. The printing machine particularly comprises a succession of printing units, at least one pulse generator, two pull rollers located downstream of the printing units, a combination of plate cylinders and compensating rollers to correct some register errors, scanning heads each located near and downstream to the respective printing units. Each printing unit particularly includes one of the plate cylinders as well as one of the pressing cylinders. Each pressing cylinder is controlled by a control unit.
