Abstract

An inking system for a printing machine which has a relatively simple design and which is adapted for more stable ink transfer to a plate cylinder. The inking system includes an ink supply roller (15), one or more drivable inking unit rollers (14, 19), an adjustment system for establishing a predetermined nip (19) between the ink supply roller and one of the drivable unit inking rollers (14, 19), and at least one movable calender roller (10) in constant contact with one of the drivable inking unit rollers operable for selectively interrupting the ink transfer.
