Abstract

An inking unit uses circumferentially offset elongated flexible doctor blades to form an ink chamber into which the screened surface of an ink roller immerses itself. Free ends of the spaced flexible doctor blades can be forced into or out of contact with the screened roller surface in accordance with the pressure of the ink in the ink chamber.
