A variety of stencil printing, using a screen made from fabric (silk or synthetic) stretched tightly over a frame. The non-printing areas on the fabric are blocked out by a stencil which can be created by painting on glue or lacquer, by applying adhesive film or paper, or painting a light-sensitive resist onto the screen which is then developed as a photograph (photo-screenprint). Ink or paint is forced through the open fabric with a rubber blade, known as a squeegee, onto the paper. Screenprinting has been used commercially since the 1920s and by artists since the 1950s. When it was taken up by artists in 1930s America the term 'serigraph' was used to denote an artist's print, as opposed to commercial work. The term 'silkscreen' (silk was originally used for the mesh) was and still is used, particularly in America.
