摘要

A method by which the time taken for confirmation of a color from the request for toning to the end of toning is shortened. A spectrocolorimeter (201) on the confirmed side reads a confirmation color to be confirmed, calculates, for example, the spectral reflectances in discrete 16 to 32 points in the visible wavelength band of 380 to 780 nm (Step S101), and calculates the tristimulus values (X, Y, Z) from the calculated spectral reflectances (Step S102). A communication terminal (203) on the confirmed side sends the tristimulus values (X, Y, Z) to the confirming side through a communication line (Step S103). A communication terminal (204) on the confirming side receives the tristimulus values (S, Y, Z), and then a color printer (205) on the confirming side reproduces the confirmation color from the tristimulus values (X, Y, Z) (Step S104).
