Abstract
A method of compensating for vibration-induced circumferential-register errors in a sheet-fed printing press includes compensating for at least one vibration-induced deviation of an actual angular position of a cylinder from a nominal angular position by adjusting the circumferential register of at least one printing unit, in particular of the cylinder. For this purpose, the current vibration state of the sheet-fed printing press is determined, the effect of the determined vibrations of an integer order on a position of color excerpts on a sheet of printing material is calculated, and the compensating circumferential-register adjustment required in accordance with the result of the calculation is carried out. A sheet-fed printing press for carrying out the method, is also provided.
