Spectral prediction of spot color ink has always been a difficult problem in the field of color research. The current paper adopted color parallel and superposition models to deal with the Clapper-Yule model and to simplify the prediction model of spectral reflectance of spot color ink. respectively. Based on the experimental verification. the simplified method has a certain practical application value. and the spot color prediction of general presswork can meet the requirements fully. The most important consideration is that the simplification can largely reduce the computational difficulty. Moreover. the current paper compared the accuracy of color parallel model with the superposition model to simplify the spectral prediction model of spot color ink. The result showed that the color superposition model has higher accuracy in simplifying the spectral prediction model of spot color ink.
