Abstract

An image forming system includes an image output device, a measurement sensor, a tone correction value generation unit, and a tone correction unit. The image output device outputs an image on a recording medium with a mixture of a plurality of basic colors based on an image data array combining the basic colors. The measurement sensor measures a reflection characteristic of at least a part of the image output by the image output device. The tone correction value generation unit generates, for each of the basic colors, a tone correction value for correcting a tone characteristic of the basic color by synthesizing a correction array forming a regular matrix based on the reflection characteristic measured by the measurement sensor and the image data array. The tone correction unit corrects an image output by the image output device with the tone correction value.
