The present invention is related to a printing unit including a frame (2) and an upper plate cylinder (12) mounted in the frame (2). An upper blanket cylinder (16) is in selective contact with the upper plate cylinder (12), and a lower blanket cylinder (18) forms a nip with the upper blanket cylinder (16). A web (8) passes through the nip. A lower plate cylinder (14) contacts the lower blanket cylinder (18). Impression setting means (60, 62, 82) are assigned to movable housings (40, 44) of the movable cylinders (12, 14, 16). The impression setting means (60, 62, 82) are provided to adjust forces exerted on bearers (20) of the printing unit cylinders (12, 14, 16).
