Information processing apparatus, image forming apparatus, and image forming system

An image forming apparatus comprising:

• a formation unit that forms an image on a medium by using a plurality of color materials;
• and
• a processor configured to:
• in a case where a first color material, a second color material, a third color material, and a fourth color material in which a difference between the first color material and the fourth color material in a color space is less than a threshold value, are capable of being used in the formation unit, output combinations of values of color materials reproducing a first color, which is used for expanding a color gamut of a secondary color of the first color material and the second color material, and a second color, which is used for expanding a color gamut of a secondary color of the first color material and the third color material.

An information processing apparatus comprising:

• a processor configured to:
• in a case where a first color material, a second color material, a third color material, and a fourth color material in which a difference between the first color material and the fourth color material in a color space is less than a threshold value, are capable of being used, generate
• a first color chart in which colors that are reproduced by a combination of a color of the first color material, a color of the second color material, and a color of the third color material are arranged,
• a second color chart in which colors that are reproduced by a combination of the color of the first color material, the color of the second color material, and a color of the fourth color material are arranged, and
• a third color chart in which colors that are reproduced by a combination of the color of the first color material, the color of the third color material, and the color of the fourth color material are arranged.
