ABSTRACT:
An ink ejection amount error is acquired for each of a plurality of same ink nozzle arrays for ejecting same ink. Line sets consisting of N adjacent main scan lines are classified into a plurality of line set types LT11to LT13according to a ratio of the pixel counts allocated to the plurality of nozzle arrays on the line set. Using the ink ejection amount error of each nozzle array, the average ink ejection error δ is obtained for each of the line set types LT11to LT13. The ink amount data on each main scan line of each line set is corrected using the average ink ejection amount error for each line set.
