Title (EN) PHOTOSENSITIVE PRINTING PLATE
(FR) PLAQUE PHOTO-SENSIBLE
Abstract: front page image
(EN)A printing plate is produced by the steps of preparing sensitive layer-forming photosensitive composition containing an organic foaming agent and, upon drying of the composition, thermally decompose the organic foaming agent to roughen the surface of the photosensitive layer. The process in accordance with this invention requires no special mechanical treatment for forming the photosensitive layer, eliminates the need of rearrangement or modification of existing coating equipments and also drastically decreases a working time for vacuum-contact operation, thus resulting in an efficient fabrication of printing plate and a greatly reduced production cost.
(FR)Une plaque sensible est produite en preparant une composition photo-sensible formant une couche sensible et contenant un agent de moussage organique qui, apres sechage de la composition, se decompose par la chaleur pour rendre la surface de la couche photo-sensible rugueuse. Le procede ne demande aucun traitement mecanique special pour former la couche photo-sensible, elimine le besoin de redisposer ou modifier les equipements de revetement existants et diminue considerablement le temps de travail sous vide, ce qui permet une fabrication rentable de plaques d"impression et d"un cout de production extremement reduit.
