    摘要: The invention relates to a method and apparatus for setting register on a multicolor printing machine (1) having color printing units (6, 6null, 6null, 6null) allocated to various printing inks and having image cylinders (2, 2null), equipment (3, 3null) for producing images, in particular electrostatic latent images, on the image cylinders (2, 2null, . . . ), a carrier (4) for printing substrates (15) and image transfer points (5, 5null, 5null, 5nullnull) for the transfer of the color separations (7, 7null, . . . ) from the color printing units (6, 6null, 6null, 6nullnull) to the printing substrates (15), an allocation of the image productions (11, 11null) on the image cylinders (2, 2null, . . . ) to the printing substrates (15) being carried out in order to achieve coincidence of register of the color separations (7, 7null, . . . ) in the print. Apparatus and methods of this type are to be configured in such a way that a high precision in setting the register can be achieved with a tolerable outlay, in particular as far as possible without reject prints. This is achieved by a time-independent allocation of the positions of the image productions (11, 11null, . . . ) on the image cylinders (2, 2null, . . . ) to the printing substrates (15) being carried out for at least one defined area (10, 10null, 10null, . . . , 10n) of all the color separations (7, 7null, . . . ).

    摘要: The invention relates to a method and apparatus for correcting register faults in a multicolor printing machine (1) having a number of items of equipment (2,2null, . . . ) for the digital production of color separations (3,3null, . . . ), correction values being determined and assigned to the angular positions (4,4null, . . . ) of at least one image cylinder (5,5null, . . . ) and, as a result, being taken into account for the control of the production of the color separations (3,3null, . . . ) on said image cylinder. By means of the invention, correction values are to be made available for the correction of register faults, which, with a fine graduation, make it possible to assign them to angular positions of machine elements in a repeatable way. This is achieved by circularity errors (6,6null, . . . ; 8,8null, . . . ; 9) of machine elements (5,5null, . . . ; 7,7null, . . . ; 10) which have an influence on the register being determined, assigned to their angular positions (4,4null, . . . ; 13,13null, . . . ; 14) and, from these, the correction values for the control of the production of the color separations (3,3null, . . . ) on the at least one image cylinder (5,5null, . . . ) being determined.
