摘要
描述了一种利用调频加网进行半色调图像防伪。提出一种通过网点扩大补偿的分析进行防伪的方法。该方法比现有的防伪方法更简便易行。
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.
