Research On FM Color Model

This paper aims to do research on FM color model.Usually conventional Offset technics use AM Screening. Moire debase the printing quality in multi-color pringting. Because of the dot randomicity, FM Screening avoid the limitation of AM Screening.So.it have the significance to research and use FM Screening.It is required to found FM color model in order to use FM Screening better.control and analyse the color copy.In this paper we adopt the graphics segmentation theory to acquire the dot areas. We use the Yule-Nielson formula to acquire value n .analyse the Neugebauer equation, find Nx, Ny, Nz and establish the FM color model. In the end, we validate the FM color model and educe the conclusion.This paper is helpful to dot area measuring and FM color copy.
