| 摘要 |
A printing apparatus of the present invention includes a dither processing unit which converts multi-value data of C (cyan), M (magenta), and Y (yellow) into binary CMY data, and further includes a black generation processing unit which generates a gray plane by a logical product between C, M, and Y of the binary CMY data, and generates K (black) at positions of some of gray pixels of the gray plane according to a probability responsive to a density of the gray pixels in the gray plane while refraining from generating K at positions of remaining gray pixels. <IMAGE> |
