Abstract
An apparatus and a method for evaluating control marks on printing materials by an optical sensor connected to a computer, which interprets overshooting of a predefined intensity threshold as it registers the printing material being a line of a printed control mark. The apparatus is distinguished by the fact that the control mark is registered by a color measuring instrument and that the intensity threshold of the optical sensor is calculated by the computer in dependence on the measured color value registered by the color measuring instrument.
