PROCESS FOR THE TREATMENT OF PHOTOSENSITIVE LAYERS, CONTAINING DIAZOIC COMPOUNDS, THAT WORK POSITIVELY, EXPOSED TO LIGHT AND REVEALED, DURING THE PRODUCTION OF 'OFFSET' PRINTING MOLDS

摘要

The invention relates to a process for the burning-in of positive-working, light-sensitive layers, containing diazo compounds, during the preparation of offset printing forms, by heating the printing plate. In this process, the light-sensitive layer is treated, after exposure and development, with electromagnetic radiation having an infrared fraction, a fraction in the visible region, and an ultraviolet fraction.
