Abstract (en)
During the manufacture of packages, printed sheets (F) are transported, by clamp bars (6) through a cutting-out station (2) of a machine. In a part of the machine located before the front waste (Df) ejection (8), a "CAMERA FLASH" unit (10) produces an image of a front waste Df zone where printing registration marks and at least a part of its cut-out are located. Then, image processing and comparison of a real image with a reference image allow the quality monitoring of the package, in particular with regard to the colour registration and the position of the printing with respect to the cutting-out. <IMAGE>
