Dupont ImagON TM Ultra is a light-sensitive, photopolymer film designed to adhere to a copper plate creating a photo intaglio plate. The film/plate is then exposed to U. V. light and developed with soda ash and water. The film may be removed from the copper plate after use and the copper plate reused. An exposure system and vacuum frame are required to process correctly. ImagON TM film may be cut to custom size using a razor knife.
