目的 为了提高高仿真艺术品色彩再现的稳定性，有效改善色度复制中同色异谱现象所引起的缺陷，提出一种色彩校正模型。方法 在传统色彩再现模型的基础上选取Y-N模型进行改进，进一步利用YNSN模型进行优化，从而得出精准的非线性校正n值，再选取光谱均方根误差和拟合度为控制参量，根据光谱均方根误差最小且拟合度最高的原则来选取最优n值，以提高复制品色彩再现的精确度和稳定性。结果 实验结果显示，最终获取的非线性校正n值分别为青2.7814、品2.9312、黄3.9621、黑5.0116；与之相对应的平均光谱均方根误差达到0.0265，平均拟合度达到0.9972。结论 该模型能有效地校正艺术品的色彩再现，且具有较高的色彩校正精确度。

The work aims to increase the stability of color reproduction of high-simulation artworks and improve de-fects caused by metamerism in chroma replication so as to propose a color correction model. Y-N model was selected for improvement based on traditional color reproduction model. The YNSN model was used for optimization to obtain accurate yule-nielson correction coefficients. Then, the RMS error of the spectrum and the fitting were selected as the controlled variables. According to the minimum RMS error of the spectrum and the highest degree of fitting, the optimal value of n was selected to improve the accuracy of the reproduction color. The experimental results showed that the final linear correction values of n were: C 2.7814, M 2.9312, Y 3.9621 and K 5.0116, the average RMS of the spectrum reached 0.0265, and the average degree of fit was 0.9972. The model can effectively correct the color reproduction of the artwork and has high color correction accuracy.
