  • Process and apparatus for producing printing plates
    Patent number: 4985322
    Abstract: The process and apparatus for producing printing plates of this invention are for optically color separating a transmitted light or reflection light from a color original (1) and producing color-separated printing plates (18) each having each different color by the color-separated light. Hitherto, each color-separated printing plate of each color is produced by photographing a color-separated light, i.e., color-separated images using a photographic film such as an expensive silver salt photographic film, etc., and printing the color-separated images thus photographed using the photographic film as an intermediate onto a printing plate such as a pre-sensitive printing plate, etc. On the other hand, in this invention, each color-separated printing plate (18) is directly produced from a color original without using a photographic film such as an expensive silver salt photographic film as an intermediate by using an organic photoconductive material having a whole light wavelength of from 400 n.m. to 700 n.m.
