Abstract: A printing screen, comprising a sheet, at least sections of at least one pair of opposite edges of which are folded such as to define attachment elements, and a printing screen unit including at least one pair of interface members attachable to the attachment elements at the at least one pair of opposite edges of the sheet.

Abstract: A printing screen unit including a printing screen having two pairs of opposite edges and a frame including interface members bonded to opposite edges of the printing screen and coupled together at corners of the frame, wherein the frame holds the printing screen in an untensioned state when no tension is applied thereto by external tensioning mechanisms separate to the frame, and the frame is substantially rigid when in the untensioned state, but allows for relative movement of the respective pairs of interface members by a tension applied by external tensioning mechanisms separate to the frame to tension the printing screen.
