PROBLEM TO BE SOLVED: To prevent an image quality degradation due to bleeding and clogging. SOLUTION: When a fine mode is selected as a printing mode, a total volume of ink droplets of black discharged from nozzles corresponding to one dot on a paper is controlled to form a small ball. At the same time, each total volume of ink droplets of yellow, magenta and cyan is controlled to form a minute ball. Bleeding of the black ink and the other color ink is thus suppressed without changing the ink composition. COPYRIGHT: (C)2004,JPO |
