1. An apparatus comprising: a unit configured to determine whether or not a color material saving mode is set; a unit configured to cause a printing unit to print a large dot region by using a first value and a small dot region by using a second value, in a case where the color material saving mode is set, and to cause the printing unit to print a large dot region by using a third value and a small dot region by using a fourth value, in a case where the color material saving mode is not set; and a unit configured to cause the printing unit to print patches for setting the second value and the fourth value, wherein each of the patches includes the large dot region printed by using the first value and the large dot region printed by using the third value and a small dot region, and a density of the small dot region in each of the patches is different from a density of the small dot region in each of the other patches.
