Abstract (en)

[origin: EP1156381A2] Method in which correction values are determined and applied to angular positions of one or more image cylinders (5, 5') and hence to control of the partial color images. Concentricity errors for machine elements (5, 5', 7, 7', 10) that influence the register are determined and from these correction values for control of generation of partial color images(3, 3') which are applied to one or more image cylinders. The invention also relates to a device for correction of register errors in multi-color printers that uses a memory for recording machine specific concentricity errors and assigning them to angular positions as machine specific nominal values.
