Abstract:
1. An image forming control apparatus that performs gradation correction process to adjust a density of an image formed by the image forming apparatus, the image forming control apparatus comprising: a gradation correction curve generator that generates a gradation correction curve based on a correspondence between output instruction values each representing a density of an image to be formed by the image forming apparatus and actual density values each representing a density of the image formed by the image forming apparatus, wherein the gradation correction curve is a curve which represents a relationship between the output instruction values and corrected output instruction values, and the output instruction values are corrected to the corrected output instruction values by the gradation correction curve; and a calibration data generator that, when the corrected output instruction value corresponding to a maximum value of the output instruction values is smaller than the maximum value of the output instruction values in the gradation correction curve, corrects the gradation correction curve so that the corrected output instruction value corresponding to the maximum value of the output instruction values coincides with the maximum value of the output instruction values, and generates the calibration data based on the corrected gradation correction curve.
