The screen printing process uses a porous mesh screen made of fabric or stainless steel stretched tightly over a frame made of wood or metal. A stencil is produced on the screen either manually or photochemically to define the image to be printed. Ink is then forced through the fine mesh openings using a squeegee that is drawn across the screen. Ink will pass through only in areas where no stencil is applied, thus forming an image on the page.
