ABSTRACT:
A method of preparing a permanent photopolymer master with a permanent latent image for use in electrostatic image transfer to a receiving substrate is provided in which the photopolymer master is first flood pre-exposed to increase the resistivity of the entire photopolymer material and then is selectively exposed for a second time to form the permanent latent image in areas of high resistivity and to leave the background areas of the photopolymer with lower resistivity.
