Apparatus for simulating color printing process

摘要: An apparatus for simulating a color printing process comprises scanning unit including table on which four separation films formed from original are placed side by side, pair of flying spot scanner tubes, lens systems projecting raster images the tubes onto and photomultipliers converting light rays passing through respective into subtractive primary signals cyan, magenta, yellow black; control effecting various adjustments correction upon zero adjuster, an after image corrector, continuous tone gamma screen soft/hard negative/positive flat etching device, contrast shadow adjuster partial adjuster; reproduction adjusted corrected additive red, green blue; monitor receiving cathode ray tube displaying image. The has chrominance characteristic can completely display actual colors about 700 to 800 lines per frame.
