Abstract:
1. A printing screen unit, comprising: a printing screen, comprising a sheet having two pairs of opposite edges, at least sections of which include attachment elements; and a frame including first and second pairs of interface members attachable to the attachment elements at the respective pairs of opposite edges of the sheet and corner pieces coupling adjacent ends of each of the interface members, wherein the frame holds the printing screen captive in an untensioned state when no tension is applied thereto by external tensioning mechanisms separate to the frame, the frame having no element or device mounted thereto nor carried thereby for maintaining the printing screen in a tensioned 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.
