Abstract
In a method for registration correction for a multicolor rotary printing press in an acceleration phase, having at least one registration correction device with correction parameters for operation of constant speed, and having a motion controller for controlling the print roller speed, if the registration correction device is acted upon in the acceleration phase by at least one fixed set of the correction parameters, which differs from the correction parameters at constant speed, and/or in the acceleration phase, a correction profile that is modified compared to constant speed is used, and/or information about the presence of the acceleration phase is supplied by the motion controller to the registration correction device, then it can be attained that in both methods, during the acceleration phase, the corrector continues to remain active, and even in this phase, it compensates for registration deviations. By the set of correction parameters that is modified compared to constant speed, or correction values, the registration corrector can be optimally adapted to requirements during the acceleration phase, and thus minimal registration offset can be attained. After the acceleration phase, the correction parameters or correction values are reset to the values before the acceleration phase for constant speed.
