Contact exposure of a photopolymer through a halftone separation film with a high intensity ultraviolet light causes the photopolymer to become insulative in the exposed area. The photopolymer will retain its conductive properties in the unexposed area. In this way, a latent image is recorded on the photopolymer. If the latent image is developed with a black developer material which is fixed thereto, the photopolymer may be used for plate making.
