ABSTRACT:
The object of the present invention is to adjust relative misalignment of recording positions of dots created at different timings with high accuracy, thereby enhancing the printing quality.A patch pattern is used as a test pattern for adjusting misalignment of recording positions between a first dot and a second dot created at different timings. In the test pattern, a fraction of the first dot and the second dot adjoining to each other in either a main scanning direction or a sub-scanning direction may be significantly greater than a fraction of the first dots or the second dots adjoining to each other. In the test pattern, substantially equal numbers of the first dot and the second dot may be created with a substantially equivalent dispersibility over a practically whole area.
