Abstract

A web-fed offset printing machine includes printing units having at least one form cylinder and one transfer cylinder; and at least one folder unit; and wherein, for each printing unit, at least one of the form and transfer cylinders has a drive connection to a separate electric motor, the at least one cylinder has either no mechanical drive connection to a further one of the cylinders in case the further cylinder is driven directly or indirectly by a further separate electric motor, or a mechanical drive connection to one of the further cylinders in case the further cylinder is non-driven; the printing machine further includes a motor control system for the at least one electric motor for adjusting a printing group and for presetting the printing units for adaptation to either a different web path or production configuration, the motor control system has an input side; and a computing and memory unit for storing a plurality of cylinder positions connected to the input side of the motor control system.
