Abstract

Large-format composite relief printing plates are produced by applying individual photopolymerizable relief printing plates to a large-format substrate, by a process in which the image information is transmitted to the individual relief printing plates by means of a laser. The individual photopolymerizable relief printing plates are positioned on the substrate with the aid of a laser. A composite of relief printing plates comprises a substrate, a laser-structurable layer applied thereon and insoluble in printing inks and printing plate developers, and relief printing plates applied thereon and having an IR-ablatable layer.
