Tensioned printing screen frame, assembly and method

Abstract

Disclosed is a printing screen assembly, a frame for a printing screen and method for their construction. The printing screen assembly has a frame (310) with an elongate first frame member (320, 320a) and an elongate second frame member (320, 320b) parallel to the first frame member (320, 320a) and in fixed relation thereto; and a corresponding cantilevered first and second tensioning arrangement (326) extending from each frame member (320) along a length thereof. A predictable pre-tensioning force may be applied by resiliently deflecting the tensioning arrangements (326) into contact with an abutment arrangement (328) and securing a printing screen to an attachment portion (326b) of the first tensioning arrangement (326a), while the first tensioning arrangement (326) is in contact with the first abutment arrangement (326a). The frame may be formed by preselecting the resilience of the tensioning arrangement (326) so as to preselect the tension applied when tensioning a printing screen in use.
