Abstract
A method for pre-registration in a printing machine with multiple printing units in which phases of the printing cylinders involved in the printing process are so mutually attuned that the deviations of the printing images of the different printing cylinders lie within mutual capture areas, includes using the deviations in the context of the registration of an ongoing printing operation, respectively, for the determination of the position of the printing images or parts thereof. The web to be printed, which is fed during the pre-registration to the printing machine, has at least one mark, which passes through different printing units during the pre-registration. The time points at which the mark passes the measuring points in the printing units are recorded, and these time points are set with reference to the angular position of the printing images of the respective printing units at those time points.
