Abstract

The invention relates to a method for controlling a machine processing sheet material. The processing machine has at least one printing or coating group and a cylinder that is coupled to a direct drive and is decoupled mechanically from a main drive acting on a gear train of a plurality of sheet transport cylinders and that can be driven in a given way at least relative to the sheet-guiding cylinders. The cylinder having an associated inking group with an inking group roller that can be driven by the main drive and gear train. Printing contact in a contact zone of the cylinder carrying the printing form with an adjacent rubber blanket cylinder is cancelled for cleaning. The inking group roller of the inking group is separated on a drive side from the sheet transport cylinders driven by the main drive and gear train. The inking group roller is coupled on the drive side to the cylinder carrying the printing form. The inking group roller is driven according to a cleaning program stored in a selection menu for an individual cleaning period at an individual rotational speed by the direct drive.
