Abstract

A printing machine with at least one inking unit which has at least two cylinders which are set against each other during the printing operation and can be rotated by at least one drive. The printing machine is provided with sensors for recording parameters of the rotary motion of the cylinders such as the torque and speed. A setting mechanism is provided for setting the at least two cylinders against each other in radial direction. The control unit is configured to trigger the setting mechanism to set the at least two cylinders against each other. The at least two cylinders are brought to different circumferential velocities and set against each other. The relative position of the two cylinders is recorded or maintained when at least one parameter of the rotary motion of the at least two cylinders exceeds a threshold value.
