ABSTRACT:
The position of sheets in a printing press is measured. A problem in transporting sheets through the printing press is how to guarantee the correct orientation and lay of the sheets, which must be guaranteed particularly in the printing operation. There is provided a device for precisely determining and correcting the positions of sheets in printing presses. Margin regions of a sheet are respectively imaged, projection data are transmitted to a computing unit, and the position of the sheet is calculated with the aid of the projection data by way of an image recognition algorithm. Furthermore, the computed positions of the sheet are compared to positions which are stored in the computing unit, and from the comparison, position deviations are computed, which are transmitted to the printing press and corrected by way of a sheet registration device.
