PURPOSE:To improve the calculation precision of a combinational formula of specific dyes for obtaining the same hue with a color sample by obtaining experimentally a dyeing property parameter showing the relation between the ability of a dye to dye a fiber independently and the ability to dye in the presence of another dye, and making corrections by dyes. CONSTITUTION:When specific dyes are combined to obtain a body color having an optional spectral reflection factor curve by a computer color matching method, a dyeing property parameter indicating the relation between the ability of a dye in use to dye a fiber independently and the ability to dye in the presence of another dye is calculated by experiment. A formula calculated by using dyeing property parameters obtained by experiment is corrected, dye by dye, to improve the calculation precision of a combinational formula of specific dyes for obtaining the same hue with a color sample. For the purpose, >=1 kind of mixed dyed body with an optional ratio is produced and dyeing property parameters of respective dye groups are calculated from the relation with the color matching formula based upon the same dyes for the actual formula of the dyed body. |
