Patent ID: 8263314

Claim:
A method for preparing a composite printing form comprising: a) providing one photosensitive element comprising a layer of a photopolymerizable composition and an infrared sensitive layer disposed above the photopolymerizable layer, the element having a planar area; b) positioning the element adjacent a carrier having no marking or indicator for positioning of the element, wherein the carrier has a leading end and a planar area, and the planar area of the one photosensitive element is at least 70% of the planar area of the carrier; c) securing the element to the carrier; d) imagewise exposing the infrared sensitive layer with infrared laser radiation to form a mask on the element; e) overall exposing the element to actinic radiation through the mask; and f) treating the element of e) to form a relief structure on the carrier, and wherein the method further comprises attaching a mounting bar to the leading end of the carrier.
