发明名称 Correlating cyan and magenta planes for error diffusion halftoning
摘要 <p>The present invention performs error diffusion halftoning while taking into account multiple color planes, such as cyan and magenta, when determining the placement of a dot in any of the color planes. Using this technique, printed dots (4, 6) of two or more colors are dispersed so as to avoid noticeable clumping of dots of two or more colors. This technique can be used to augment any existing error diffusion method. &lt;IMAGE&gt; &lt;IMAGE&gt;</p>
