Method and apparatus for color processing in color image reproduction system

摘要

The present invention relates to a color processing method and apparatus in a color image reproduction system, and it is a method of removing color by subtracting the minimum color of the three primary colors of subtractive color mixture produced from the three primary colors of the additive color, Generating black to compensate for the optical density that can not be reproduced by the three primary colors of the subtractive color mixture, adding the black of the lower color and the compensating black, Are reproduced in a predetermined output device with the three primary colors of the mixed color elimination technique and the final output black color added four colors. Therefore, the color can be accurately reproduced, and clear text and black thin line images can be obtained.
