Objective To study the anti-counterfeit technology for high-end printing through grating materials. Methods Combined with special optical properties of grating material and halftone image screening technology, invisible latent image anti -counterfeit technology was presented, and based on the minimum threshold matrix theory, variable angle screening anti-counterfeit technology was achieved. The principles of each anti-counterfeiting technology were discussed in detail, and these algorithms were implemented based on photoshop and matlab programming. Results EPSON Stylus Pro7880C was used as the image output device. In the invisible latent image anti-counterfeiting technology, when the grating line screen angle on printing was 45^o or 135^o , the hidden latent image information could be clearly seen. During the variable angle technology, the corresponding grating was superimposed on the watermarked image with a specific angle of 21. 14^o , the anti-counterfeit information could be clearly observed. Conclusion Experiments showed that raster invisible latent anti-counterfeiting technology had a good performance in security printing.
