Zusammenfassung:	A doctor blade bar assembly supports spaced doctor blades which are resiliently carried by slidable base bodies that can be moved to throw-on or adjust the doctor blades with respect to a screened ink roller. A pair of blade base shifting devices are secured to doctor blade base support beams. The shifting devices utilize rotatable eccentric cams to move the base bodies along guide surfaces on the beams. The doctor blades are moved in a linear manner to resiliently engage the screened ink roller at a negative contact angle. End plates on the base bodies cooperate with the spaced, resiliently supported doctor blades to form an ink receiving chamber.
