Abstract

A method and apparatus for setting registration in a multicolor printing machine (1) having a number of exposure devices (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 registration, such that in-register prints are achieved, influencing variables (4, 4′, 4″) which are caused by the printed pages and have an influence on registration being taken into account in setting up and combining the color separations (3, 3′, . . . ) before the onset of a change in said influencing variables. Therefore, no interruption of the printing process between two different printed pages (33, 34) is necessary.
