Abstract: Disclosed is a precision cut printing screen in which the features of a printing pattern are defined on a sheet material by a plurality of apertures within a target printing boundary. Also disclosed is a method of making the printing screen.

Abstract: Disclosed are methods of manufacturing a workpiece fixture (10) and also a target material fixture (10), for use in precision manufacturing processes. A sheet material is supported on a generic material fixture (10) and the sheet material precision processed to form support blades (16, 18) for a target workpiece fixture (10). Each support blade (16, 18) has a support locus and interstices are positioned in the support loci where a target pattern and the support loci coincide. Thus, there are no unnecessary clearances between the workpiece support (10) and the workpiece. The interstices that are present are located only where necessary to reduce or eliminate any interference between the precision manufacturing process and the fixture (10), when it is used in a precision process involving the target pattern.

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.

Abstract: A frame unit for tensioning a printing screen, the frame unit comprising a frame including at least one frame member, the at least one frame member comprising: a supporting frame element; at least one engagement element for engaging a fitted printing screen to tension the same, wherein the at least one engagement element comprises a body which is pivotally coupled to the supporting frame element such that the at least one engagement element is pivotable in one, tensioning sense to tension a fitted printing screen and the other, opposite sense to adopt a configuration in which a printing screen can be fitted to or removed from the frame unit, a first, engagement arm extending from the body for engaging a fitted printing screen, and a second, biasing arm extending from the body to which a biasing force is applied to bias the at least one engagement element to pivot in the tensioning sense; and at least one biasing element operative to apply a biasing force to the biasing arm of the at least one engagement eleme
