These printmaking plates are made from clear, non-tinted PETG plastic. They are ideal for monotype, carborundum, collagraph and drypoint processes as well as photopolymer films. The soft, yet malleable surface allows for easy incising of lines and is made of .030 PETG transparent plastic that is durable, yet softer than polycarbonate. It has a non-porous surface to prevent ghosting.
