Part of the Multimedia and graphics glossary: Screen printing, also known as serigraphy, is a method of creating an image on paper, fabric or some other object by pressing ink through a screen with areas blocked off by a stencil.
Method in which ink is applied directly to the surface to be printed (substrate). The image to be printed is photographically transferred to a very fine fabric (the screen) such that the non-printing areas are blocked off and the fabric serves as a stencil. The ink is wiped across the screen to pass through the unblocked pores and reach the substrate.
