Beschreibung
Zusammenfassung:	A process for the production of a linework and/or halftone pattern comprising the steps of : (1) forming without wet processing an ultraviolet radiation (UV) absorbing line work and/or halftone mask by transferring at least one ultraviolet absorbing compound from a heat-sensitive recording layer onto an UV-transparent image receiving material, said transfer proceeding by pixelwise heating said recording layer to make the ultraviolet absorbing compound(s) form in the image-receiving material a pixel density of at least 2 in the spectral range of 300 to 450 nm, and (2) contact-exposing an UV-radiation sensitive imaging material through said mask to obtain in said imaging material a detectable change in chemical or physical properties. k
