Abstract:
1. A method for controlling register settings of a printing press, comprising the steps of: rotating imaging cylinders of a first print unit and a second print unit, located downstream of the first print unit in a movement direction of a print medium, at a rotational speed to print an image on the print medium; changing a length of the print image to a predetermined length; and changing a register setting of the imaging cylinder of the second print unit based on the predetermined change in length of the print image to avoid misalignment of the print image printed by the first and the second print units on the print medium, wherein the changing of the register setting is dependent on a length of a section of the print medium between the first and the second print units, wherein changing the register settings of the imaging cylinder of the second print unit includes the steps of: determining a number of print images between the first and second print units by dividing the length of the section of the print medium between the first and second print units by the length of one print image, as seen in the movement direction of the print medium; and multiplying the change in the length of the print image by the number of print images between the first and second print units.
