Process for obtaining half-tone picture of irregular structure |
摘要 |
A process for obtaining a half-tone picture of irregular structure consists in exposing a coarse-grained silver-halide material with an average linear size of silver halide micro-crystals of 4 to 6 microns, developing the exposed material in an infectious developer, printing the resulting picture on a high-contract photosensitive material, and developing the exposed high-contract photosensitive material. The process permits obtaining a high-quality half-tone picture with the optical densities of the original being reproducible within the range of more than 1.0. The process is simple and easily controllable.
