1. A method for setting a device for image reproduction on printing plates, the device having at least two image reproduction members provided for reproducing image parts of a printing image seamlessly and without any offset with respect to one another by assigning desired positions to the image reproduction members, which comprises the steps of: checking actual positions of the image reproduction members at least in relation to one another by checking the actual positions of the image reproduction members in an X-direction and/or a Y-direction substantially orthogonal to the X-direction, and, the checking step being performed by the further steps of: performing at least one of: reproducing on a printing plate, in the X-direction of each of the image reproduction members, at least one first pattern overlapping in each case with the first pattern of at least one adjacent image reproduction member; and reproducing on the printing plate, in each case with a right and a left column, in the Y-direction of each of the image reproduction members, in each case at least three second patterns spaced apart from one another in a longitudinal direction, such that in each case the right column of an image part of an image reproduction member is at least contiguous to the left column of an adjacent image part; and compensating for and/or preventing undesirable effects of mispositions thereby determined by use of at least one of the first and second patterns.
