The printer has at least two printing stations which cause images to be printed on a substrate. The printer is capable of registration adjustment. First and second patterns of spaced registration marks are printed onto the substrate by operation of the printing stations. The second pattern partially overlaps the first pattern to form a composite pattern of registration marks. The composite pattern is illuminated and the reflectivity thereof is examined at wavelengths complementary to the colors of the first and second patterns to obtain a reflectivity signature for the composite pattern. The reflectivity signature of the composite pattern (120) is compared with a predetermined signature to determine an adjustment factor for the printer.
