| 摘 要： | 通过分析影响彩色塑料包装印刷品色彩再现的影响因素并考虑了油墨与塑料底基折射率的差异,把入射光透射到底基后的反射光光分为Fresnel反射光与漫反射光;结合油墨的吸光特性、塑料的光学性质,利用Williams-Clapper理论,用辐射传递法对各种影响因素进行分析,得出塑料包装印刷品反射率的数学模型.

| Abstract: | Several important factors influencing the color reproduction of plastic package was analyzed. The reflections were divided into Fresnel reflections and diffusing reflections when light propagated the plastic substrates, considering different plastic substrates coated with non-diffusing coloring ink of different refractive indices. A model for predicting the reflectance was put forward accounting for the optical property of ink, plastic, and the absorption of the ink using radiometric approach. |
