Abstract
A method and apparatus for setting register on a multicolor printing machine (1) having color printing units (6, 6′, 6″, 6′″) assigned to various printing inks, at least one image cylinder (2, 2′, . . . ), image production equipment (3,3′, . . . ) for producing color separations (7, 7′, . . . ) on the at least one image cylinder (2, 2′, . . . ) and a carrier (4) for printing substrates (15). An assignment of the image production points (11, 11′, . . . ) on the at least one image cylinder (2, 2′, . . . ) is carried out in order to achieve coincidence of register between the color separations (7, 7′, . . . ) in the print, by both the production of the image starts (10) and the production of areas (10′, 10″, . . . , 10n) of the color separations (7, 7′, . . . ) set on the basis of the print and the evaluation of register marks (9, 9′, 9″, 9′″).
