摘要:
After a first scan in a forward direction, conveying corresponding to one nozzle block is performed, and then in a second scan in a backward direction, printing of a “printing area 1,” which is a unit area, is completed. Then after completion of printing of the unit area, conveying corresponding to 14 nozzle blocks is performed. Then by reciprocal third and fourth scans, printing of a “printing area 2” is completed in a likewise manner. Subsequently, two scans in a reciprocal manner are performed in a likewise manner to perform printing of each unit area. In any unit area, printing time intervals between scans are such that, at a same position in a scan direction, the time interval is the same. Consequently, differences in density between unit areas that are adjacent in a conveying direction of a printing medium, that is, between-band unevenness becomes more difficult to recognize.
