Abstract
Abstract In a procedure for determining register errors on a printed product provided with register marks (4, 5, 6), the register marks (4, 5, 6) being scanned optoelectrically when the printed product passes through the printing machine, the register marks (4, 5, 6) are scanned by sensors (3) having at least four sensor elements arranged essentially in a square. In this case, the register marks (4, 5, 6) each have two edges extending at opposite angles obliquely relative to the direction of web travel. <IMAGE>
