A composite panel for use in the manufacture of a letterpress plate has a carrier layer, with at least one photo layer which can be structured via electromagnetic radiation in a wavelength range. The photo layer is arranged on the carrier layer. The task of proposing a composite panel use in the manufacture of a letterpress plate is achieved by the fact that a barrier layer is provided. The barrier layer is arranged on the side of the photo layer opposite to the carrier layer. The barrier layer is essentially transparent in the wavelength range in which the photo layer can be structured. The present disclosure concerns a process for manufacturing a letterpress plate using at least one composite panel and a process for manufacturing a composite plate in accordance with the invention. The invention concerns the use of a composite material in a composite panel for a letterpress plate.
