Abstract
A method of detecting the positional accuracy of register and any of folding and cutting-edge positions, respectively, on flat copies, including scanning a prescribable recording field on the copy by a detector, which comprises determining the position of the printed image and of the folding and cutting edges, respectively, by contrast transitions extending through screen fields.
