ABSTRACT:
An improved method of screen gravure photoengraving using a half-tone positive in which the gradation is fully represented by the variations of both sizes and depths of ink cells formed in the printing plate and the formation of moire pattern can be prevented without requiring strict registering in exposure steps, and the method comprises the steps of, for example, exposing a photosensitive material such as a carbon resist to a light source through a gravure screen having transparent crosslines, further exposing the photosensitive material to the light source through a half-tone positive, again exposing to the light source by interposing a diffusion sheet between the half-tone positive and the photosensitive material, then transferring thus exposed photosensitive material on a gravure cylinder and carrying out developing and etching.
