把油墨与纸张等价为吸收薄膜,考虑光在纸基油墨间多重内反射和横向传播,运用吸收膜理论,建立了半色调商标印刷品的Clapper-Yule 色彩预测膜层模型。通过数值计算并与实验值比较,证明了新模型的预测精度明显高于之前的Murray-Davies 模型,而且改进了经典Clapper-Yule 模型预测偏暗的问题。

Ink and paper was equivalent to absorbing film. Clapper-Yule color prediction film model for halftone logo printing was established using absorbing film theory and considering multiple internal reflection and transverse propagation of light in paper-based ink. Through numerical calculation and comparison with experimental value, it was proved that the prediction precision of the new model is apparently higher than Murray-Davies model and the dark problem of classical Clapper-Yule model was solved by the new model.
