About this term
Source: Oxford University Press
Twentieth-century printmaking technique developed from Stencilling. It is commercially known as screen process printing or silkscreen; a group of American artists renamed it serigraphy in 1940 to denote its use for fine art. A gauze textile—originally of organdie or silk, more recently of synthetic fabric or wire—is stretched on a frame. The stencil is made by selectively blocking parts of the mesh. A thick ink is wiped across the mesh with a blade called a squeegee, so that it passes through the unblocked areas on to the surface to be printed.
