Objective To set up a micro-mirror pixelgrams model for anti-counterfeiting in logo printing. Methods Based on the characteristics of double cosine micro-mirror which satisfies Jacobian determinant criterion of the micro surface reflective brightness and reflective stability and also based on light reflection. Results A new kind of RGBS structural printing anti-coun-terfeiting micro-mirror model suitable for logo printing was established. The surface structure of the model function was simulated and analyzed. Conclusion The model utilized the periodicity of cosine function and adjusted the structure parameters to achieve the anti-counterfeiting purpose.
