In some examples, a sheet-fed printing unit is configured as a screen printing unit and includes at least one screen printing forme cylinder and at least one impression cylinder cooperating therewith. A cylinder barrel of the impression cylinder includes a supporting surface for sheets, and which includes at least one impression portion having a constant barrel radius that extends over an angle of at least 170 degrees about the axis of rotation of the impression cylinder. The screen printing forme cylinder has an effective screen radius that is smaller than a barrel radius of the impression cylinder, and the effective screen radius is larger than half the barrel radius.

Screen coating jig for screen-coating surface of plate-shaped member having protrusion to cross protrusion with sealing member, including: jig body having higher rigidity than sealing member to be placed on surface of plate-shaped member. Jig body includes: first surface facing surface of plate-shaped member; second surface on opposite side of first surface; and pair of dividing surfaces extending from first surface to second surface and dividing at least part of jig body into first portion and second portion. First surface includes recess to be fitted to protrusion of plate-shaped member starting from intersection portions with pair of dividing surfaces. Pair of dividing surfaces has uniform height from first surface to second surface. Width between pair of dividing surfaces is narrowed at position corresponding to recess.
