These printmaking plates are made of a flexible plastic ideal for monotype, carborundum, collagraph and drypoint processes as well as photopolymer films. Because of its soft flexibility, this plate is easy to transport from workstation to press. This also reduces the chance of buckling while you print and makes it easy to peel away from finished prints.Details:Clear22.5" x 30.5"PlasticSuitable for use with any water- or oil-based inkEasy to clean
