摘要： An undershot inking unit and associated method are disclosed. The undershot inking unit includes an ink fountain roller that is controlled independently of the printing speed of the printing machine, and in which the rotational contact angle of the distributor roller on the ink fountain roller is varied according to the printing unit speed. The method comprises controlling the rotational speed of the ink fountain roller independently of the printing speed of the printing machine; and varying the rotational contact angle of the intermittent ductor roller on the ink fountain roller according to the printing speed of the printing machine. In a preferred embodiment, the apparatus includes two coaxial cams rotatably adjustable with respect to each other. Each cam includes a predominant circumferential contour and a subordinate circumferential contour. By adjusting the relative rotational position of the cams, the rotational contact angle of the ductor roller on the ink foundation roller is varied according to the printing unit speed.

摘要： An ink metering system for a roller train in a printing machine which in the illustrated embodiment includes a fountain roller and a downstream train of rollers communicating with a plate or form cylinder of the printing press. One or more plating devices (12) are provided which each have a plate-like element (19) adjustably positionable with respect to a respective roller for leveling ink on the surface of the roller before or after passage through a contact zone with an adjacent roller in which ink is pulled off and separated between the rollers. The plating devices are relatively simple in construction and operation and provide stable ink guidance on the roller surfaces that noticeably improves print quality.
