Abstract
Detection of crosstrack aberrations of registration marks in order to prevent color errors during multicolor printing. The detection of crosstrack aberrations of registration marks is with a single sensor which detects each triangle as a registration mark per color selection, whereby the triangles are each assigned a color of the multicolor printing. Sensor values are detected and formed from these differential values.
