Abstract:
A printing unit that prints an inspection image, a reading unit that reads the inspection image printed by the printing unit, and an analysis unit that performs analyzation based on a reading result read by the reading unit are provided. The inspection image includes an inspection pattern of a plurality of colors, the inspection pattern including a first position detection mark printed in a first color, a second position detection mark printed in the first color, and a second color inspection pattern printed in a second color different from the first color, the printing unit prints the second color inspection pattern at a position adjacent to the first position detection mark, and the analysis unit specifies a first position of the first position detection mark in a first region, and specifies a second position of the second position detection mark in a second region smaller than the first region.
