Printing black and white reproducible color documents |
摘要 |
A color image is reproduced with a set of colors wherein each color is defined in terms of a pattern block. Pattern blocks include a pattern using the color to be reproduced and white in density-related combinations so that the luminance difference between the color and white can be retained when copied or printed with a black printer. The patterns add among colors thus allowing combination colors to be represented in terms of added patterns of colors represented in black as distinct patterns.
