Abstract
An image formation apparatus for forming an image and test patterns. The image formation apparatus includes a storage unit that stores dither matrix data used to form the image and the test patterns; and an image formation unit that forms the test patterns based on the dither matrix data. A number of tones of the test patterns to be formed by the image formation unit is changed and the number of tones is determined based on a size of the dither matrix data and a number of bits per pixel within the dither matrix data.
