PURPOSE:To provide a color printer preventing the color slurring of the printed results of binary black-and-white images or the reduction of resolution in the case of printing image data prepared by synthesizing color images such as natural picture, etc., and binary black-and-white image data such as characters or line drawings, etc. CONSTITUTION:The corresponding bit of a bit map 12 is turned to '1' when a line drawing extracting circuit 20 extracts the dots constituting a black character/black line drawing from synthetic image data prepared by synthesizing color image data and binary black-and-white image data. A color output control circuit 15 turns the CMY (three primary colors) of chrominance signals top '0' when the bit of the bit map memory 12 is '1' corresponding to the dots of chrominance signals from a color correction circuit, 14, K (black) is transformed to a maximum value and outputted, and a printer engine 16 executes printing only with K ink. |
