Abstract (en)
[origin: EP0813961A1] The printing device has an inking unit (5) containing inking rolls (3.1-3.4) rotating positively and in contact with transfer rolls and ink applying rolls (4.1-4.4) The inking rolls can be driven at a circumferential speed differing from that of the plate cylinder (2). Those colour rolls (3.3 and 3.1) which are remote from the plate cylinder are driven at a greater difference in circumferential speed from that of the plate cylinder than those (3.2,3.4) which are adjacent to the plate cylinder and in friction contact with the changeable ink applying rolls.
