A method is known of compensating for misregistration during operation of a printing
press, in particular a sheet-fed offset printing press, in which misregistration
occurring in the individual printing units are countered by register corrections.
In order to provide a simple method to reduce misregisters after a pause in printing
and in particular after washing of the rubber blanket cylinder, the pattern of
the misregistration (PD) after a pause in printing is determined in a calibration
phase over a sufficient number of sheets, data as a function of the pattern of
the misregistration is stored in a memory unit (15) so that register correction
values (Ki) may be determined and the register correction values are applied to
the printing press upon restart after the pause in printing in order to compensate
for the misregistration.
