A process for manufacturing photopolymer blocks, which are first exposed to UVA radiation and mounted on printing cylinders to in combination form a printing sleeve for carrying out printing in flexography and in dry offset, includes a series of automated steps for manufacturing the printing sleeves. A device for implementing the process includes a series of stations, arranged in line, one after the other, including a storage magazine for receiving the exposed printing sleeves, a solvent-vapor lock, an etching device, a drying device and a storage station for receiving the completed printing sleeves.
