油墨渗透下荧光半色调印刷品的预测模型

Prediction Model of Fluorescent Halftone Presswork under Ink Penetration

旨在普通油墨渗透条件下,建立能预测不同浓度的均匀荧光油墨半色调印刷品的呈色规律的理论模型;在假定油墨是非散射介质以及油墨的折射率与纸张的折射率近似相等的近似下,利用光在油墨与纸张中散射迁移路径长短不同的分程理论,建立了油墨渗透下荧光油墨半色调图像的分程Clapper-Yule光谱反射率模型。

Under ink penetration condition, the theoretic model to predict color presentation of fluorescent halftone presswork was established. It was assumed that the ink is non-scattering media and refractive index of the ink is close to which of the paper. A distance Clapper-Yule spectral reflectance color prediction model for fluorescent halftone presswork was established by making use of the theory of the light propagation in paper with long and short distance model.
