<p><P>PROBLEM TO BE SOLVED: To suppress the occurrence of banding, when performing multipass recording. <P>SOLUTION: When print data on AM dot data is produced by an RIP 12, in an inkjet printer 20, the print data is divided into 4×4 pixel blocks Z by a mask pattern processing unit 41 and the dot recording order of each pixel in each block Z is decided based on a mask pattern. At this point, as the dot recording rank of each pixel in the mask pattern, first pixel groups A which are not adjacent vertically, horizontally, or diagonally are placed in a first rank position, second pixel groups B arranged on the right and left of the first pixel groups A are placed in a second rank position, third pixel groups C arranged on the top and bottom of the first pixel groups A are placed in a third rank position, and fourth pixel groups D arranged diagonal to the first pixel groups are placed in a fourth rank position. Then, each pixel is rearranged in order of actually recording a dot, based on nozzle arrangement and the conveyance schedule of an inkjet head 32 by a rearrangement processing unit 42. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
