摘　　要：为了获得单色料反射率随着可见光波长和染料质量占比变化的函数,提出一种单色料反射光谱曲面配色方法.首先,根据染料质量占比与可见光波长的范围将单色料反射光谱曲面划分为9个曲面片;然后,采用多项式建模方法,构建不同曲面片的单色料反射光谱曲面模型,并通过小样实验验证该方法的准确性.实验结果表明:通过有限组小样实验可以构建单色料反射光谱曲面,确定单色料反射率随着染料质量占比和可见光波长的变化关系,预测布匹在单色料染色后的颜色与目标色的色差.In order to obtain the function of the single dye reflectivity varying with the visible light wavelength and the dye mass ratio, a color matching method of single dye reflection spectrum surface was proposed. Firstly, according to the range of dye mass ratio and visible light wavelength, the single dye reflection spectrum surface was divided into nine surface sheets. Then, the polynomial modeling method was used to construct the single dye reflection spectrum surface models of different surface sheets, and the method accuracy was verified by sample experiments. The experimental results show that the single dye reflection spectrum surface can be constructed through a limited group of sample experiments, the varying relationship between the single dye reflectivity and the dye mass ratio and the visible light wavelength can be determined, and the color difference between the color of the cloth dyed with the single dye and the target color can be predicted.
