Abstract
A method for compensating torsional vibrations of a printing machine by introducing torques which compensate vibration excitation, includes determining at least one characteristic form of a printing machine for at least one location on a drive train of the printing machine, determining and storing at least one respective countertorque for compensating the torques which excite vibration in a characteristic form at a location whereat the characteristic form is not zero, and applying the at least one countertorque at the corresponding location so that the vibration is maximally reduced due to the application of the at least one countertorque.
