发明名称 Color separation production using color recognition circuit
摘要 The invention relates to a method for producing line and continuous tone color separations of pattern models of textile, decoration or packaging printing and the like, and further relates to a color scanner. A characteristic color recognition signal for controlling the recording is obtained by color recognition for each pattern color from the color measured value signals gained by opto-electric scanning of the pattern models. For the production of line color separations, an adjustable color separation signal, which corresponds to the desired recording density, is prescribed. For the production of continuous-tone color separations, a run signal, dependent on the color saturation and/or brightness of a color in the pattern model, is derived from at least one measured color value signal and the corresponding color separation signal is derived therefrom. In the recording of the color separation of a color, the color recognition signal of this color controls the color separation signal in such a manner that the color separation signal is switched on, given the presence of the concerned color in the pattern model, and is switched off when that color is not present.
