Paper Abstract

The research of color prediction model is one of the most important tasks in print reproduction. By the conception of regular quadriface composed of two bifaces we obtain the global transfer matrix of the quadriface from the single-step transition probability matrix of the Markov chain. According to the optics character of transparent plastic substrate, using the Markov chain of stochastic process theory, considering the fact of total reflectance when light propagate to optically thinner medium (air) from denser medium(ink and plastic substrate),we modify the mathematic model of reflectivity and obtain the mathematic reflectivity model of plastic substrate homochromous presswork.
