Abstract
Moire patterns with many characteristics such as high reliability,strong exclusive,simple process,low cost,as a means for security are widely used in the field of packaging and printing.The Mohr's theory,generation and principle of moire pattern anti-counterfeiting are analyzed.The some easy image informations are hidden in the pre-copy color images.The how screening shapes,screening percentage,screening frequency and screening angle to affect sub-image and how to choose the color channel to embed the sub-image on condition of two printing colors are analyzed.Through experiments,suitable color moire pattern anti-counterfeiting parameters are gotten.The screening parameters achieved can be used in designs of halftoning moire security and can provide references for the field of embedding moire patterns in color printing products for security,which have a good applicability.

期刊介绍：
The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months.
The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
