Study on Moire Pattern-Based Printing Anti-counterfeiting Technology

Moire security is a type of information hiding technology based on optics.Authentication of packaging by moire patterns was discussed for the anti-counterfeiting technology based on general printing.The generation and principle of moire pattern anti-countfeiting were analysised.We designed the moire pattern with the hiding information by Illustrator and applied it to packaging design.The packaging design was printed by digital proofing to verify it's anti-counterfeiting performance.The result shows that the packaging with the hidden information by the moire anti-counterfeiting technology is revealed after desoding,and a certain authentication effect is obtained. Finally the moire pattern-based production process in printing anti-countfeiting,the detail for moire pattern design and the method for improving the anti-countfetiting performance of moire pattern are put forward.The corresponding solution is also presented.
