摘　　要：尤尔-尼尔森光谱纽介堡公式中修正系数的确定一直是个难题。选用了纸张的光谱反射率的倒数作为修正系数,使计算的有效网点面积率与实际的网点面积率之间的误差减小。结果表明,修正后的尤尔-尼尔森光谱公式可用于有效网点面积率的计算,研究结果对于印刷色彩检测具有重要意义。Determination of correction factor of Yule-Nielsen spectral neugebauer （YNSN） model is a difficult prob- lem. The reciprocal of paper＇s spectral reflectance was applied as the correction factor of Yule-Nielsen spectral neuge- bauer model to reduce the error between calculated and practical dot area rate. The result showed that the modified YNSN mode can be used to calculate the effective dot area rate. The purpose was to provide reference for controlling and testing printing color.
