  • Patent number: 4401750
    Abstract: A method using a relatively coarse grained film photographic image produces a photo etched image having photographic-print-quality in that the image displays gradations of contrast throughout representative of light, shadow and contour. The visual effect is that of an image reproduced by use of halftone cuts. The difference, however, lies in that halftone imagery is produced by component particles of uniform size whereas the granular structure of the coarse grained photographic image on the film is more random in nature.
