发明名称 Inkjet printing apparatus and inkjet printing method
摘要 Provided is an inkjet printing apparatus for performing a printing with a first nozzle array for ejecting a first color ink and a second nozzle array for ejecting a second color ink. The apparatus reduces density unevenness stemming from a sudden error in conveyance of a printing medium. When the apparatus performs a scan with respect to the printing medium for printing in which using ranges of nozzles in the first and second nozzle arrays are restricted to parts thereof, the restricted using ranges of the first and second nozzle arrays are shifted from each other. Thereby, the density unevenness stemming from the error in conveyance occur in positions which are different between the first and second colors, Thus, it possible to make the overall density unevenness less obvious by making gradients of variations in brightness and chroma of an image smaller.
