Abstract

A method sets up a device for image reproduction on printing plates. The fastening of image reproduction members, their orientation and tolerances, and also tolerances in the positioning of the image reproduction members on a guide or a spindle, lead to mis-positions of the image reproduction members in relation to one another. Offsets of two adjacent image parts may occur. In the method, the printing plate has reproduced on it in the X-direction at least one first pattern which overlaps with the first pattern of an adjacent image reproduction member and/or the printing plate, in each case with a right and a left column, has reproduced on it in the Y-direction in each case at least three spaced-apart second patterns, such that in each case the right column of an image part is at least contiguous to the left column of an adjacent image part.
