Abstract
When the color printing is performed using a recording head arranged such that number of nozzles for discharging black ink is greater than the number of nozzles for discharging inks of other colors, the use frequency of some nozzles among all the nozzles for discharging the black ink is higher, so that image unevenness may arise when transferred to the black printing. The present invention relates to an ink jet recording method and an ink jet recording apparatus in which the image unevenness often seen in the black printing involving the use of more nozzles than other colors, and the blur of recorded image seen in the image having black images adjacent color images located are reduced.
