Abstract: A process for the manufacture of rollers for the printing of laminar materials, a machine for carrying out the process and a printing support for printing rollers. A printing support is wholly manufactured within an irradiating machine equipped with visible marks located on the lower plate and on the machine. The laminar support supports the plates positioned on a dimensionally stable substrate sheet on which marks are made accurately in the same location relative to the overall image as a reference axis for subsequent positioning on the roller and on which also matching marks are printed or engraved. Some of these marks are repeated on films which restrict the passage of ultraviolet light, one of the films having transparent areas which present elements of one colour of the image which has to be printed while the remaining film represents mounts surrounding such elements.
