Abstract
Process for broadening the processing range of photohardenable negatively functioning reproduction materials wherein the unexposed areas are removed by liquid development and while still in contact with the developer the material is diffusely exposed to delayed actinic radiation, the delayed exposure amounting to at least 5% of the time necessary to clear the unexposed material.
Claims5
Process for broadening the processing range of photohardenable negatively functioning reproduction materials wherein after imagewise exposure the unexposed areas of the material are removed by washing out with a developing solution, characterized in that the material, while in contact with the developing solution, is diffusely exposed to actinic radiation following a delay in exposure which amounts to at least 5% of the time necessary to clear the unexposed photohardenable material.
