Abstract

The invention discloses a method for making a multi-encoded encrypted dynamic pixel holographic master pattern. The steps are as follows: 1. Using CorelDRAW or Illustrator or Photoshop software to design the pattern, and converting the graphic pattern into a bmp format; 2. Using Photoshop's "filter "mirror function" and "feathering function" to process the image; 3. Use the selection tool in photoshop to separate the graphics in different areas into different layers to form multiple graphics files; 4. Input the layered graphics into the holographic lithography system one by one , use pixels of different sizes and shapes, and different grating pitches to make layered graphics, record these pattern codes on a recording board through lithography equipment, and recombine to form a complete pattern. The grating orientation coding of the hologram produced by the method produces non-directional variation, and various strange changing effects are obtained. Different holographic pattern designs combined with different effect processing of different image processing functions produce unrepeatable variation effects and play the role of encryption and anti-counterfeiting of patterns.
