When sheets of paper or carton are fed into the press singly, this is referred to as sheet-fed offset printing. If the paper is fed from rolls, which may weigh up to several tonnes, this is called web offset printing, which is further subdivided into illustration and newspaper printing.
Single-drive technology has established itself in web offset printing. This means that each printing unit has its own servomotor. The axes are synchronized by a virtual leading axis. However, a main drive with a drive wheel train is still used for sheet-fed offset printing because of the risk of collision.
