Abstract
An image forming control apparatus includes: a gradation correction curve generator and a calibration data generator. The gradation correction curve generator generates a gradation correction curve based on a correspondence between an output instruction values each representing a density of an image to be formed by an image forming apparatus and actual density values each representing a density of the image formed by the image forming apparatus. The gradation correction curve represents a correspondence between predetermined standard density values and the output instruction values. When an output instruction value corresponding to a maximum standard density value is smaller than a maximum output instruction value, the calibration data generator corrects the gradation correction curve so that the output instruction value corresponding to the maximum standard density value coincides with the maximum output instruction value, and generates the calibration data based on the corrected gradation correction curve.
