A screen printing piece is made of a
piece of porous, finely woven fabric (originally silk, but
typically made of nylon since the 1940s) stretched over a wood or
aluminium frame. Areas of the screen are blocked off with a
non-permeable material—a stencil—which is a negative of the image
to be printed; that is, the open spaces are where the ink will
appear.
The screen is placed on top of a piece of dry paper or fabric. Ink is placed on top of the screen, and a (rubber blade) is used to spread the ink evenly across the screen. The ink passes through the open spaces in the screen onto the paper or fabric below; then the screen is lifted away. The screen can be re-used after cleaning. If more than one color is being printed on the same surface, the ink is allowed to dry and then the process is repeated with another screen and different color of ink.
