ABSTRACT:
A method and apparatus for applying newsprint ink and dampening fluid to a lithographic printing plate, the apparatus comprising an ink metering roller in rolling pressure indented relation with a transfer roller having an oleophillic surface and a dampening fluid transfer roller having a hydrophillic surface each of the transfer rollers being driven by a reversible variable speed motor. The transfer rollers are in pressure indented relationship with a form roller which transfers a thin film of ink and dampening fluid to the printing plate. An excess of ink is supplied to the nip between the metering roller and the transfer roller to produce the thin film of ink which may be further conditioned by an ink storage roller prior to entry of the film of ink into the ink transfer nip between the transfer roller and the form roller. By controlling the relative speeds between the form roller and the transfer roller, slippage occurs which meters a thin film of ink onto the form roller for transfer and application to the printing plate.
