Abstract

A printing press includes a plurality of mutually mechanically decoupled printing-unit groups each having at least one individual printing unit. A drive for the printing press includes drive motors each being associated with a respective one of the printing-unit groups. Devices are each associated with a respective one of the printing-unit groups for rotational-speed and/or angle-of-rotation determination. An angle feedback control device dimensions a permissible angle-of-rotation deviation of the printing-unit groups from a preselected angle setpoint value in such a way that the deviation is minimal at least in an angle-of-rotation position in which sheet transfer takes place.
