ABSTRACT:
To permit selective operation of an ink supply as a continuous film inking system, or as an intermittent lifter ink system, with low ink supply operating speeds, the ink distribution rollers (2-6; 8-11, 18) of the ink roller distribution train are divided into two groups (A, B) which are separated from each other by a gap. The gap may be narrow 0.05 mm wide, permitting operation of the rollers of one group (A) at a speed which is about half the circumferential speed of the rollers of the other group (B) and in contact with the plate cylinder (1) of the machine; or the gap may be wider, for example 3 mm or more, and bridged by a roller system in which a plurality of roller elements (13) are retained in a cage (7), with two rollers (14, 15) of larger diameter projecting from the cage for frictional engagement with adjacent rollers of the two groups of the distribution rollers operating at different speeds. The arrangement permits selective operation of the plate cylinder at higher than previously possible speeds without splashing or spraying of water-ink emulsion off rollers of the inking system upon printing on plate carriers of substantially smaller format than the plate cylinders, leaving unused ink-water emulsion on the roller.
