准确预测印刷品的颜色一直是印刷复制中一个十分重要的课题。基于光能的辐射传递理论，通过分析光在油墨层表面及内部传播过程中的散射与吸收等规律，并引入荧光激发函数，对Kubelka-Munk模型预测印刷品时蓝紫波段反射率偏差的问题进行了修正，并建立了新的印刷品光谱反射预测模型。该模型可为计算机光谱配色和高精度仿真印刷系统的开发提供理论基础。

It is an important problem to predict the color of print accurately for printing. A new spectral reflection prediction model for print was established by introducing a fluorescence excitated function based on radiant transfer theory which can describe the phenomenon of the flux scattering and absorbing on the surface of ink as well as in the ink layer. The new model corrected the problem of Kubelka-Munk model for error prediction on the reflectance of blue and violet wave band. The new model can be used for developing computer spectral color matching systems and high-quality simulated printing system.
