A method and apparatus for detecting and correcting color deviations in multicolor printing

摘要

The invention relates to the field of multicolor printing devices - and in particular on the recognition of cross track - deviations or - displacements of register marks to avoid errors in the color printing. Dollars a is a method and a device are provided, which in the case of the multicolor printing cross track - deviations of register marks with a single sensor and in each case a single triangle as the register mark for each color separation, the triangles in each case are associated with a color of the multicolor printing is increased. For this purpose, sensor values are detected and formed from these difference values.
