| 摘 要： | 在考虑网点扩大的情况下,研究了基于Murray-Davies方程的调频网半色调印品色彩预测模型。分析了调频网印品图像的微观结构和特征,建立了理想状态下调频网的反射率模型;考虑到光在纸基中的散射,采用光散射概率理论构建了墨点与墨点间的局部反射与透射关系;最后,建立了基于扩展的Murray-Davies方程的调频网半色调图像的微观色彩预测模型。

| Abstract: | Considering the case of dot gain,a color prediction model of FM halftone printed image based on Murray-Davies equation was studied.The microscopic structure and characteristics of FM halftone image was analyzed and a reflectance model for FM halftone image in ideal state was established.Taking into account the influence of light scattering,the relationship of reflection and transmission partially for dots and vacancy between dots was analyzed using the theory of light scattering.Based on the analysis above,a new prediction model based on expanded Murray-Davies equation for FM halftone printed image on microscopic level was developed. |
