Abstract
A print medium is conveyed in a first direction and a print head is provided with a reference side nozzle array and a plurality of nonreference side nozzle arrays. A relative position displacement amount between a reference printing position of a reference pattern printed by the reference side nozzle array and a nonreference printing position of each of nonreference patterns printed by each of the nonreference side nozzle arrays is detected. Based on a maximum value of a displacement amount of the reference printing position with respect to each of the nonreference printing positions in a direction opposite to the first direction, a first correction value for correcting displacement of the reference printing position is calculated. With reference to the reference printing position after corrected based on the first correction value, a second correction value for correcting displacement is calculated for each of the nonreference printing positions.
