Claim 0:
1. A sheet-fed printing unit (700), the sheet-fed printing unit (700) being configured as a screen printing unit (700) and comprising at least one screen printing forme cylinder (752) and at least one impression cylinder (708) cooperating therewith, and at least one further rotational transport body (709; 711; 712; 713), and a fixing element of the at least one impression cylinder (708) having an inner contact surface (748) and an outer contact surface (749), which are arranged so as to cooperate for clamping sheets (02), and the inner contact surface (748) being at least partially located at a distance from an axis of rotation (716) of the at least one impression cylinder (708) which corresponds to a base radius (R0), and a cylinder barrel (741) of the at least one impression cylinder (708) having a supporting surface (744) for sheets (02) that includes at least one impression portion (746) having a constant barrel radius (R1), which extends over an angle of at least 170° about the axis of rotation (716) of the at least one impression cylinder (708), and the barrel radius (R1) being larger than the base radius (R0), and a fixing element of the at least one further rotational transport body (709; 711; 712; 713) having an inner contact surface and an outer contact surface, which are arranged so as to cooperate for clamping sheets (02), and the inner contact surface being at least partially located at a distance from an axis of rotation (717; 718; 719; 721) of the at least one further rotational transport body (709; 711; 712; 713) which corresponds to the base radius (R0).
