Claim 8:
9. The image printing apparatus according to claim 1, wherein the setting step includes:
a selection step of selecting a predetermined number of the dot-arrangeable-subpixels from the dot-arrangeable subpixels included in the extended pattern;
a calculation step of calculating an evaluation value indicating dot dispersibility of each of the selected dot-arrangeable subpixels;
a changing step of changing the selection of the dot-arrangeable subpixels in the extended pattern based on the evaluation values to obtain higher dot dispersibility in the extended pattern; and
a setting step of setting the thresholds to the pixels of the dither pattern corresponding to the dot-arrangeable subpixels in the changed extended pattern.
