ABSTRACT:
A greasy ink printing press including a rubber coated inking cylinder coacting with a plate cylinder has an inking device comprising a wiping cylinder formed by a small diameter rod pressed against the inking cylinder in a zone of downward movement thereof, with an ink trough formed in the space above the zone of contact of the rod and inking cylinder. A variable-speed electric motor rotates the rod in the same direction of rotation as the inking cylinder to laminate the ink between the rod and inking cylinder and provide a counter-current wiping of the inking cylinder. The rod may be reciprocated longitudinally to remove streaks.
