Abstract
A keyless inking system for lithographic printing presses wherein an ink/water mixture is contained in an ink pan having a tray portion within which an ink roller is mounted whereby ink/water mixture enters the tray portion on one side and is drawn by the ink roller to the other side of the tray in the nip between the ink roller and a celled metering roller thereby delivering an excess of the mixture to the celled metering roller, the balance of the mixture being conveyed over a weir into a reservoir for continuous mixing and recirculation back to the pan, and wherein the excess ink/water mixture on the metering roller is continuously scraped off by means of a doctor blade and wherein the metered portion of the ink/water mixture remaining in the metering roller's cells is delivered in part into the inking train of a more-or-less conventional lithographic printing press.
