    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.
