ABSTRACT:
Screen printing and stencil articles, apparatus and methods provide a stencil including a screen and photosensitive emulsion for selectively stopping areas of the screen upon photographic exposure and development. One or more sheets are adapted to receive an image pattern through which the photosensitive emulsion is to be exposed. The photosensitive emulsion is shielded against spurious exposure. The screen with shielded photosensitive emulsion and the one or more pattern receiving sheets are combined into a unitary stencil making assembly.
A stencil comprises a rectangular screen having meshes. A first area on the screen is stopped and a second area adjacent the first area comprises open meshes of the screen. A first elongate screen mounting member is attached to and extends along a first side of the screen. A second elongate screen mounting member is attached to and extends along an opposite second side of the screen. The screen itself is self-supporting between the first and second mounting members.
