In the above-described example, the second relational equation is obtained as follows in Step S150. Hereinafter, the gradation value as a target for which spectral reflectances are to be obtained by the second relational equation will be referred to as a “process target gradation value.” The gradation value for which the spectral reflectances are obtained regarding the reference color or the characteristics-acquired gradation value becomes the process target gradation value. For example, an equation that represents a relationship between the spectral reflectances of the gradation value of 1 and spectral reflectances of a gradation value of 0.7 with the spectral reflectances of the gradation value of 1 being taken as the first reference and with the spectral reflectances of the gradation value of 0.5 being taken as the second reference is obtained as a second relational equation for obtaining the spectral reflectances of the gradation value of 0.7 for the prediction target color. Moreover, for example, an equation that represents a relationship between the spectral reflectances of the gradation value of 0.5 and spectral reflectances of a gradation value of 0.2 with the spectral reflectances of the gradation value of 0.5 being taken as the first reference and with the spectral reflectances of the gradation value of 0 being taken as the second reference is obtained as a second relational equation for obtaining the spectral reflectances of the gradation value of 0.2 for the prediction target color.
