A spectral reflectances prediction program 141 for performing the spectral reflectances prediction process is stored in the auxiliary storage device 14. The spectral reflectances prediction program 141 is provided by being stored in a computer readable recording medium such as a CD-ROM or a DVD-ROM. That is, a user purchases, for example, an optical disk (CD-ROM, DVD-ROM, etc.) 170 as a recording medium for the spectral reflectances prediction program 141, mounts the optical disk 170 on the optical disk drive 17, reads the spectral reflectances prediction program 141 from the optical disk 170, and installs the read program in the auxiliary storage device 14. Alternatively, the spectral reflectances prediction program 141 sent through the communication line CL may be received by the network interface unit 18 and installed in the auxiliary storage device 14.
<1.3 Spectral Reflectances Prediction Method (Spectral Characteristics Prediction Method)>
A description will be given below of the spectral reflectances prediction process that achieves a spectral reflectances prediction method (spectral characteristics prediction method) according to the present embodiment. Note that this spectral reflectances prediction process is performed in such a manner that a spectral reflectances prediction program 141 executed by the print data generation apparatus 100.
