Abstract

A method for registering a rotary press for a printing process, in which “n” inking systems (Fn) each produce monochrome printed images and print one on top of the other thereby producing n-colored printed images, includes producing the images of a printed material with at least one sensor station, recording information on rotary movements of printing plate cylinders (Dn), and using the images and the information to produce correction signals which actuate the cylinders until a deviation of the images of the respective inking systems from a desired position on the material lies within a defined range of tolerance values. During the registering method, one printing plate cylinder at a time is in the printing position, the sensor station produces the printed images, and the correction signals are obtained based on the image produced by the respective cylinder and the information on the rotary movements of at least one cylinder.
