Abstract
To associate the ink requirement of subject matter to be printed from a printing forme (6, 27) to the ink being supplied thereto by an ink application cylinder (5, 26), the ink application cylinder is provided with a jacket, sleeve or cover having a cellular surface, and in which the cell distribution or cell configuration of the surface is matched, at least approximately, and, for example, in zones or regions, to the subject matter to be printed from the forme. The ink can be transferred by an ink application roller, in which a plate cylinder carries the forme, and the ink application roller, the plate cylinder and the cylinder with the cellular surface cover all have essentially the same diameter and are all driven at the same speed. Pre-forming the cell distribution or cell configuration on a jacket or cover, which may be in form of a plate applied to the ink supplying cylinder, or a sleeve, can accurately meter ink for the forme cylinder, without requiring wear-causing engagement pressures of a doctor blade against the cellular surface.
