Problems solved by technology
Traditional photographic holograms can produce encrypted three-dimensional holograms, but the main problems are: the pattern size is small, the requirements for the shooting environment are high, some production techniques are complicated, and some are inconvenient to use, and most of them are only suitable for the production of laser holographic anti-counterfeiting labels
Generally, the dynamic pixel holographic pattern is designed by using general-purpose drawing software to design the whole or partial pattern, and the resulting dynamic change effect often has certain changing rules. The problem is that the holographic master produced in this way is difficult to prevent counterfeiters from imitating

Embodiment Construction
[0035] Use the filter function of the image design and production software photoshop to process the image, and process the designed laser holographic pattern or partial graphics with various filter effects, so that the original design pattern produces graphics and color variations, and obtains a special Effect. The design of different holographic patterns combined with different effect processing of different filter functions can produce unpredictable variation effects, thus playing the role of encryption and anti-counterfeiting of patterns.
[0036] The specific steps of the method are:
[0037] The first step is to use CorelDRAW or Illustrator or Photoshop image production software to design a laser dynamic pixel holographic pattern whose graphics mode is bmp as shown in Figure 3-1. With a clear ring zoom effect, as shown in Figure 3-2 to Figure 3-5;
[0038] The second step is to use the "filter function" and "feather function" of the image design and production software ...

A multicoding encryption method for preparing the mother plate of holographic pattern with dynamically sensational pixels includes such steps as designing pattern by Corel DRAW, Illustrator, or Photoshop software, transforming the graphic format to bmp format, using the 'filter' and 'eclosion' functions of Photoshop to process the image, using the 'region choosing' tool of Photoshop to separate the graphics in different regions into different graphic layers to obtain multiple graphic files, inputting the files to holographic photoetching system one by one, preparing the hierarchical graphics the pixels with different sizes and shapes and different raster pitches, encoding the patterns, and recording on a record plate by photoetching to form a complete pattern.
Description
technical field [0001] The invention discloses a method for making a multi-coded encrypted dynamic pixel holographic master pattern, belonging to the technical field of laser processing. Background technique [0002] At present, there are two main types of laser holography on the market: traditional camera holography and dynamic pixel holography. Traditional photographic holograms can produce encrypted three-dimensional holograms, but the main problems are: the pattern size is small, the requirements for the shooting environment are high, some production techniques are complicated, and some are inconvenient to use, and most of them are only suitable for the production of laser holographic anti-counterfeiting labels . Dynamic pixel holography can realize the production of large-format master through the holographic lithography system. Its main features are: the produced hologram has a significant dynamic effect and brilliant colors. The dynamic pixel hologram is formed by t...
