Abstract
Color separations of a printing image are aligned on a printing material perpendicular to the transport direction of the printing material. A front edge and a rear edge of a register mark are detected. Their distances and, at least in some regions, their widths along the traveled distance of the transport belt between the detection of the front edge and of the rear edge of the register mark are determined. Misalignments of the imaging devices used for the color separations are determined and corrected using these distances and widths.
