Abstract

A color of a printed sample is measured to obtain a temporal change of its spectrum. Temporal changes of the other spectra are estimated from the obtained temporal change, they are converted to temporal changes of surface colors in a color space, and surface colors are estimated after a lapse of proper time from the print. Next, in order to obtain a desired surface color after a lapse of designated time, a profile is made out to convert the surface color into print data. After a lapse of proper time from a print, the print can be carried out to obtain a desired surface color.
