Silkscreen technique, also called Serigraphy, employs a sheet of material (traditionally silk, now more commonly nylon) on which the image has been blocked-out using wax or glue (or similar impermeable adhesive substance) by the artist. Ink is then squeezed over the screen onto the paper beneath, only reaching the paper where the glue or wax does not block the ink. The image is formed either by the ink or in the space defined by the ink. As with colour woodcut prints, each colour has a separate screen. The artist therefore builds the image from lighter colours to dark.
