<P>PROBLEM TO BE SOLVED: To stabilize the ejection of a small liquid droplet by a simple method. <P>SOLUTION: After converting a data resolution into the resolution (for example, 600×600 dpi) lower than a final resolution (for example, 1200×600 dpi) used with an ink-jet printer, a 3-value quantization processing is performed (200). In the case an objective pixel and the immediate preceding one are large drops, the data resolution is converted into the final resolution by assigning two large drops. For the cases other than the above, the data resolution is converted into the final resolution by assigning the data without a drop and the data of the objective pixel (202-208). <P>COPYRIGHT: (C)2007,JPO&INPIT |
