摘　　要：由于荧光纸基会吸收紫外线,激发可见蓝光或可见紫色荧光,而影响墨层厚度,为此基于荧光纸基的Clapper-Yule光谱反射色彩预测模型,考虑了荧光纸张的光学特性、光在荧光纸内部横向传播等特性,采用最小二乘参数估计方法,通过印刷品光谱反射率反映荧光纸基的墨层厚度变化量。该模型可为彩色印刷品的呈色规律分析和印刷品质量检测系统的研制与开发提供一定的理论依据。Because paper with fluorescent additives will absorb ultraviolet light while excite visible blue ray or violet fluorescence,these will certainly affect the blue or violet ink thickness.The traditional methods do not accurately reflect ink thickness changes.Based on the Fluorescent Clapper-Yule spectral reflectance prediction model,considering the expansion of ink,optical properties of paper with fluorescent additives,the internal lateral spread of light in paper with fluorescent additives and other features,an ink thickness variation prediction model was established using least square method and by spectrum reflectance of prints.The model can make a coloring analysis for color prints and provide a theoretical basis for print quality inspection systems development.
