PREDICTION OF SPECTRUM OR CHROMATICITY OF MIXED COLOR MATERIAL AND DETERMINATION OF MIXTURE OF COLOR MATERIAL HAVING DESIRED SPECTRUM OR CHROMATICITY

摘要

PROBLEM TO BE SOLVED: To directly obtain a transmissivity (or reflectance) spectrum and a chromaticity at the time of mixing color materials in various ratios from the transmissivity (or reflectance) of raw color materials, and obtain the mixture of the raw color materials to obtain the desired spectrum or the chromaticity from the transmissivity (or reflectance) of the raw color materials.;SOLUTION: A color filter has a light beam in each wavelength reduced according to a mixture ratio of each kind of color materials. This is modeled by a ratio of the film thickness of each kind of color materials, and is shown by integration of transmissivity of each layer. The object color based on reflected light is a mixture color of light reflected on the surface of each kind of color materials in each wavelength according to a mixture ratio and light reflected on a substrate by light transmitted inside a part of the color materials. This way of thinking is applied to JISZ8722, and the spectrum obtained by the mixture of each kind of color materials and the chromaticity are calculated. Further, optimization is performed by spread sheet software, and the mixture of the color materials having the desired spectrum or chromaticity is determined.;COPYRIGHT: (C)2016,JPO&INPIT
