There is a strong demand for original color reproduction regardless of the imaging device being used. To reduce color distortion and the problem of color communication, it is necessary to determine the color characteristics of each imaging device. For example, color reproduction varies between different kinds of printers because of the differences between the inks and color gamut of each device. It is well known that the ICC profile is used for printer color reproduction. This raises the issue, however, of whether the inks are manufactured using the same ICC profile. In this study, a new digital color device characterization method based on color matching using the R, G, B spectra and C, M, Y, K spectra is proposed. The ICC profile and the multiple regression analysis method are used to compare the results obtained with the characterization method. The differences between the target colors and the colors actually produced by a digital color device, for example, a monitor and a printer, using the proposed characterization method were found to be smaller than when using ICC profiles or the multiple regression analysis method when a comparison is made without considering the color mapping effect. The colors for which there is a large color difference are distributed toward the boundaries of the device's color gamuts.
