ABSTRACT:
A method for processing lenticular foil in sheet-fed printing presses is provided, the lenticular foil having lens strips adjacently disposed and extending transversely to the running direction of the sheets. The method ensures that the lens strips proceed parallel to the sheet's front edge For determining the actual position of a sheet aligned according to a front edge, the position of a contact line between two adjacent lens strips is determined, and compared with a nominal position. If the actual position deviates from the nominal position, an adjusting value is generated for realizing a leading or trailing movement of plate cylinders making possible the nominal position, of a gripper sheet-holding system of a sheet-accelerating device mounted in a drum.
