Abstract

The device for detecting print misregisters is arranged in a rotary printing machine and comprises at least a first camera (34) snapping an image of a sample area (16) of the print (12) an a travelling web (10) according to a first resolution, as well as an electronic and computer appliance (39, 50) for digitalizing the image and comparing it with a pre-registered reference image. The said camera (34) is associated with a second camera (24) snapping the global print (12) according to a second, lower, resolution, the comparative results issued by the second camera (24) being used in the counter-reaction loop of the function control of the first camera (34).
