A printing unit has two screen printing cylinders (12, 17) and a printing gap (14) formed by two cylinders (9, 16). At least the second cylinder of the two cylinders that form the printing gap is a transfer cylinder which co-operates with the second screen printing cylinder. A screen printing cylinder for the printing unit has a screen (23), a doctoring device which is situated radially inside said screen and a support element (36) which extends axially on the screen printing cylinder in the area of a limited peripheral section and which is used for sustaining a pressure exerted radially, outwards on the screen by the doctoring device when the limited peripheral section passes in front of said doctoring device.
