Abstract

The misprint detection device in a rotary printing machine comprises at least one first camera (34) for capturing, with a first resolution, an image of a sample area (16) of the print (12) on a moving strip (10) and an electronic computerised device (39, 50) for digitising the image and for then comparing with a prerecorded reference image. The first camera (34) is associated with a second camera (24) for global capture of the print (12) with a second resolution lower than the first, and the comparative results from the second camera (24) are used in a feedback loop for control of the operation of the first camera (34). <IMAGE>
