A method for checking the maintenance of register of printing images to be printed on two opposite sides of a printing material, in which the first side of the printing material is printed in a rotary printing press by a first printing unit cylinder, and in which the second side of the printing material, which lies opposite to first cite, is printed in the printing press by a second printing unit cylinder which interacts with the first printing unit cylinder. A printed image is printed by the first printing unit cylinder under the second printing unit cylinder. Afterwards, the printing material is printed in contact with the two interacting printing unit cylinders with the printing image, which is printed under the second printing unit cylinder, being printed onto the same side of the printing material together with an identical or a different printing image which is to be printed by the second printing unit cylinder during continuous printing of the rotary printing press. The printed images, which are printed together onto the same side of the printing material, are subsequently checked, with regard to their maintenance of register.
