PERFORATED FLEXOGRAPHIC PRINTING PLATES AND METHODS FOR MAKING AND USING THEM

摘要

The various inventions and/or their various aspects disclosed herein relate to novel photosensitive flexographic plates comprising a plurality of perforations dispersed over and interconnecting the base layer surfaces of the photosensitive flexographic plates. The novel perforations in the base layers give unexpected advantages as compared to photosensitive flexographic plates without such perforations, such as the ability to very significantly speed up the normally slow drying and removal of solvents absorbed into imaged flexographic plates that have been prepared by photo-imaging the novel photosensitive flexographic plates of the invention, via known and widely used processes that employ solvent treatments of the imaged plates.
