Abstract: A method will be described for the anti-counterfeiting of halftone image using microstructure screens and frequency modulation halftone screens.Through the analysis of dot gain compensating,a new method is presented.Compared with the existed method of anti-counterfeitingis,this method is proved to be easier.

Key words: anti-counterfeiting, microstructure screens, frequency modulation screens, halftone image, dot gain compensating
