ABSTRACT:
A basic gradation curve, a gray balance, and a black curve are selected, and a tone reproduction curve is generated based on a combination of the basic gradation curve, the gray balance, and the black curve which have been selected. Using the generated tone reproduction curve, a sample image is color-separated to generate a proof. The proof is checked, and, if necessary, the tone reproduction curve is corrected until an optimum tone reproduction curve is generated.
