ABSTRACT:
An inking system is provided for flowing ink on the surface of an inking cylinder in a manner that simply confines ink to the working surface of the cylinder without splatter or interference with the cylinder drive system. Thus an ink doctoring chamber is located adjacent the cylinder with a cylinder hugging chamber wall establishing an ink bearing gap over a segment of the cylinder and along its length except adjacent ink free cylinder ends. The ink doctoring chamber has a ramp sloping downwardly to maintaining the ink flow pressure within the confines of the cylinder and away from the cylinder ends. The ink flow gap is terminated at a replaceable flexible planar doctor blade slightly bent to frictionally hold it in place. Thus a simplified circulating ink flow system is provided that need not be sealed off to prevent ink splash or creepage into the printer drive system.
