Reviews of Spectral Color Reproduction Models

Utilizing the spectral reproduction thchnology to improve the accuracy of color reproduction and reduce the phenomenon of metamerism is a mainstream direction of the high-fidelity color reproduction method. In this paper, based on re viewing various types of classical spectral models, two types of spectral models were introduced which are the classical regression-based spectral model suitable for the printer and the first principals＇ models that considered physical processes. The classical regression-based spectral models suitable for the printer contain Murray-Davies model for a monochrome printer, Neugebauer model for multi-color half-tone printing, Yule-Nielsen spectral reflectance model optimizated by n value, Clapper-Yule model, Cellular-Neugebauer model, Cellular-Yule-Nielsen model, Yule-Nielsen Spectral Neugebauer model and Cellular Yule-Nielsen Spectral Neugebauer model. Through controlling each variable parameter in model, and constantly optimizing model, the accuracy of spectral color reproduction could be improved
