The invention relates to a method for registering a rotary press (3) for a printing process, wherein “n” inking systems (Fn) each produce monochrome printed images (6) and print one on top of the other thereby producing n-colored printed images, wherein the images (6) of the printed material (1) are shot by at least one sensor station (S), information on the rotary movements of the printing plate cylinders (Dn) is recorded and the images (9) [sic: (6)] and the information are used to produce correction signals, which actuate the actuators of the printing plate cylinders (Dn) until the deviation of the monochrome images (6) of the respective inking systems (Fn) from a desired position on the material to be printed (1) lies within defined range of tolerance values. The inventive method is novel in the sense that during the registering method, one printing plate cylinder (Dn) at a time is in the printing position, the at least one sensor station (S) shoots the produced monochrome printed images (6) and the correction signals for the one or more actuators of a printing plate cylinder (Dn) are obtained based on the monochrome image produced by the respective printing plate cylinder (Dn) and the information on the rotary movements of at least one printing plate cylinder (Dn). The invention also relates to rotary presses for implementing the inventive method.
Method for registering a rotary press (3) for a printing process, wherein “n” inking systems (Fn) each produce monochrome printed images (6) and print one on top of the other thereby producing n-colored printed images, wherein
Method according to the preceding claim, characterized in that the information on the rotary movements of the at least one driven printing plate cylinder (Dn), which is not in the printing position, is used in order to determine the correction signals.
Method according to the preceding claim, characterized in that the information on the rotary movements of a driven printing plate cylinder (Dn), which is not in the printing position, is used in order to determine the correction signals.
Method according to the preceding claim, characterized in that the information on the rotary movements of the printing plate cylinder (Dn), which was first in the printing position, is used in order to determine the correction signals.
Rotary press according to the preceding claim, characterized by at least one sensor station (S), which is disposed in the direction of travel (z) of the web of material to be printed (1) downstream of the last inking system (Fn).
Rotary press according to the preceding claim, characterized by a sensor station (S), which comprises two camera systems, the first of which is suitable for scanning the entire printing surface (6) with low resolution and the second of which is suitable for scanning a partial surface with high resolution.
