Abstract

PURPOSE:To enable more different kinds of color to be output than the kinds of ink prepared by forming a color tone pattern using prearranged colors in their sequential order based on the designated color tone percentage of each color, and developing it from a logic product of the color tone pattern with an image pattern into a printing pattern. CONSTITUTION:ROM 5 has a pattern area 5a which stores a priority positional order of dots in a pixel constituting an image pattern. RAM 7 has, for instance, a red and a yellow color tone flag area 7a, 7b which store a ratio of a red and yellow color tones. In addition, RAM 7 has red and yellow pattern areas 7c, 7d which store red and yellow color tone patterns respectively, and red bit map areas 7e, 7f which store red and yellow printing patterns. CPU 3 forms each color tone pattern in a prearranged color sequential order and according to their priority, based on a color tone percentage designated for each color. Then CPU develops the printing pattern of each color into the printing pattern of each color after obtaining a logic product of the color tone pattern and image pattern. After this, CPU outputs data on the printing pattern to an output part.
