    • 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.
    • 图像形成控制装置包括:灰度校正曲线发生器和校准数据发生器。 灰度校正曲线生成器基于各自表示要由图像形成装置形成的图像的浓度的输出指示值与分别表示通过图像形成形成的图像的浓度的实际浓度值之间的对应关系生成灰度校正曲线 仪器。 灰度校正曲线表示预定的标准浓度值和输出指令值之间的对应关系。 当与最大标准密度值相对应的输出指令值小于最大输出指令值时,校准数据发生器校正灰度校正曲线,使得与最大标准浓度值对应的输出指令值与最大输出指令值一致 ,并且基于校正灰度校正曲线生成校准数据。
