Screened photogravure printing method - includes sequential exposure of photosensitive material through gravure screen, positive screen and diffusion sheet

摘要

The screened photogravure method uses a positive screen. A photosensitive material is exposed to a light through a photogravure screen. This screen has the required number of crossed transparent lines. The photosensitive material is then exposed to the light through the positive screen. The photosensitive material is exposed to the light after inserting a diffusion sheet between the positive screen and the photosensitive material. The fabrication of the plate or negative is then carried out.
