Document Type and Number:
Japanese Patent JP3707321
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a high quality image in terms of a specific print head.
SOLUTION: Conveying in a sub-scanning direction is executed using a first sub-scanning driving mechanism that executes conveying in the sub-scanning direction with comparatively high accuracy and a second sub-scanning driving mechanism that executes conveying in the sub-scanning direction with comparatively low accuracy. An actuator 40 of a print head has a color nozzle array and a black nozzle array 40K. In terms of the color nozzle array, an arrangement order of a nozzle group of each ink is determined such that an yellow dot is formed behind the other dots on an arbitrary position in a printing region. In the case where color printing is executed, when the sub-scanning conveying is executed with the comparatively low accuracy at a portion in the vicinity of a rear edge of a printing paper, the printing is executed by using only a nozzle for yellow.
