ABSTRACT:
A CAMERA-FLASH unit of a feeder table of an infeed station belonging to a machine converting sheets into package is disclosed. The CAMERA-FLASH unit shoots an image of the color register marks printed previously on every sheet. The CAMERA-FLASH unit operates jointly with an IMAGE PROCESSING SYSTEM having previously memorized a reference image from a model sheet. Owing to an image process comparison of the images shot from the successive sheets to the memorized image of the model, it is possible to check whether the quality criteria of the run are fulfilled.
