Study of FM Screening Efficiency Based on Multiplicative Congruence Pseudo-Random Algorithmic

The generation of FM dot represents randomicity and its efficiency is relevant to various factors. In this paper, the issue of FM dot generation efficiency with multiplicative congruence pseudo-random algorithmic was specifically discussed. Based on the principle of pseudo-random algorithmic used in FM screening dot generation, the mechanism of multiplicative congruence pseudo-random algorithmic aimed to realize FM screening was discussed. Meanwhile, five random functions which could realize FM dot generation were brought forward and the random numbers generation efficiency of five multiplicative congruence pseudo-random functions was studied through quantificational experiments. By analyzing data and curve diagrams, the influence tendency of different conditions on the efficiency was got, which would provide theory reference for FM screening used in printing.
