以CMYKOG 六色打印系统为实例,提出了一种新的多色印刷分色算法。新算法通过颜色分区来确保多色分色的可行性,通过胞元划分来提升分色算法的精度。新的分色算法流程基于ICC 颜色管理机制,包括正向呈色模型和反向分色模型2 个主要部分,正向模型用于计算印刷色域,反向模型用于色域映射和分色计算。

A new multi-color separation algorithm was proposed with example of CMYKOG six-colors printing system. The new algorithm ensures feasibility of multicolor separation by color subarea, and accuracy of the new color separation algorithm was improved by cell division. The workflow of the new algorithm is based on ICC color management mechanism, which includes two main parts, forward model and reverse color separation model. The forward model was used to calculate printing gamut. The reverse model was used for gamut mapping and color separation.
