Estimating the term…
The invention relates to a method and apparatus for setting register in a multicolor printing machine (1) having a number of items of equipment (2, 2′, . . . ) for the digital production of color separations (3, 3′, . . . ), the actions of setting up and combining the color separations (3, 3′, . . . ) being controlled, in order to set the register, in such a way that in-register prints are achieved. The invention is based on the object of developing the method and apparatus in such a way that a change in the toner profile no longer leads to a register fault, not even temporarily. According to the invention, the object is achieved in that in the event of a change in the toner profile (5, 5′), the influence of the toner profile on the register is taken into account, by means of available influencing variables (4, 4′, . . . ) directly as the change is implemented.
