AM dot and concentric dot were taken as the main study objects. The influence of dot structure on color reproduction was analyzed. The color reproduction mechanism of high saturation concentric dot was analyzed with Clapper-Yule model and the law of Lambert-Beer. Experiments were carried out to prove the correctness of the theoretical analysis. The result showed that internal structure of dot can influence color reproduction, and the internal ring structure of concentric dot is an important factor influencing its color reproduction characteristic; concentric dot is superior to AM dot in color reproduction performance, especially in reproduction of saturation.
