The ink goes onto the areas that have been marked by grease. The paper is then passed though the press. The paper picks up the ink from the plate. The process is then repeated. The picture is gradually built up with numerous colors.
Some printings have a fixed quantity.
Each printing is signed by the artist. Each color requires a different screen. An artist draws onto a plate using grease pencils or paint. The plate may be stone, mylar, alumninum or even paper. The plate is then wetted with water and inked.
