Abstract
During, for example, package production, printed sheets are carried by gripper bars through a cutting station of a machine. Front waste strips are removed from the printed sheets and are carried to an ejection device, but before reaching the ejection device, a camera and flash scanning unit scans the area of the front waste strip which has been marked with color registration marks and also includes at least a portion of a cut edge. An image processing unit compares this sample image to a reference image to conduct a quality check on the precision of the printing and cutting registration.
