The present invention is not limited to each of the above-described embodiments (including the modified examples), and is modifiable variously within the scope without departing from the spirit of the present invention. For example, in each of the above-described embodiments, the spectral reflectances obtained by printing the target ink on the base material are predicted; however, using the method of each of the above-described embodiments, spectral reflectances obtained by printing the target ink on black can also be predicted. Moreover, the above-described respective embodiments and the above-described respective modified examples can also be implemented in appropriate combination so as not to cause contradiction.
This application is an application claiming priority based on Japanese Patent Application No. 2021-078537 entitled “Spectral Characteristics Prediction Method and Spectral Characteristics Prediction Program” filed on May 6, 2021, and the contents of which are herein incorporated by reference.
