In a printing apparatus configured to print an image by bidirectional multipass printing while using multiple print element rows that apply color material of the same color, a high-quality image suppressed in hue unevenness and density unevenness is printed. To this end, the printing apparatus forms first and second dot patterns on a print medium in an overlapping manner. In the first dot pattern, dot arrays in which first dot groups are arranged at an interval Bare arranged in a nozzle arrangement direction while being shifted from each other by Cin a scanning direction of a print head. In the second dot pattern, dot arrays in which the first dot groups are arranged at the interval Bare arranged in a nozzle arrangement direction while being shifted from each other by Cin the scanning direction of the print head. Here, values of Cand Care different.
