Abstract

Inker apparatus constructed primarily for the application of high viscosity paste-type ink includes an anilox fountain roll which partially defines an ink trough. The latter is also partially defined by a scraper blade disposed downstream of a wiper blade which forces ink into the cells of the anilox roll. The free edge of the scraper blade is disposed adjacent the cylindrical surface of the anilox roll to meter the quantity of ink which is removed from the trough by the anilox roll. Two distributor rolls are used to transfer ink from the anilox roll to a plate cylinder. One of the distributor rolls engages the image plate on the plate cylinder and the other distributor roll engages the anilox roll. The latter distributor roll is oscillated axially so that the cellular pattern of the anilox roll will not be transferred to the first mentioned distributor roll.
