PROBLEM TO BE SOLVED: To suppress generation of density irregularities. SOLUTION: A correction pattern based on a tone value is formed by forming a plurality of dot lines in a crossing direction of a relative movement direction by forming common dot lines sharing an ejection amount of fluid between corresponding nozzles with respect to the relative movement direction in a first nozzle array 411A and a second nozzle array 411B arranged partly overlapping with respect to the relative movement direction to a medium. In forming the correction pattern, when the nozzles shared to form the common dot lines are apart from each other in a direction not to partly overlap with respect to a nozzle array direction, correspondence of the nozzles is changed so as to reduce the number of nozzles corresponding to each other to be shared to form the common dot lines. A density of the correction pattern is measured for every pixel array composed of a plurality of aligned pixels in the relative movement direction. COPYRIGHT: (C)2010,JPO&INPIT |
