Abstract:
A method for the manufacture of a screen useful for forming three-dimensional films, the screens and the three-dimensional films produced using those screens are disclosed. In forming a screen, a substrate material is applied to a base. A predetermined amount of portions of the substrate are removed to form a predetermined pattern in the substrate. A screen material is applied to the patterned substrate material. A predetermined amount of portions of the screen material are removed to form a predetermined pattern in the screen material. The predetermined pattern in the screen defines a plurality of first perforations in the screen material. The substrate material is removed from the screen material, such that second perforations are formed in the screen, whereby each first perforation is in communication with an adjacent second perforation.
