Problems solved by technology

Its disadvantages are: the special paint covering is covered with lead powder printing paint, and the covering layer needs to be scraped off when reading information. After scraping off the covering layer, a magnifying glass can be used to scan and copy the ink printed by near-infrared absorbing ink. invisible graphics and information

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with embodiment:

[0040] The combined anti-counterfeiting method of the near-infrared absorbing ink and the near-infrared non-absorbing ink constitutes a combined anti-counterfeiting structure.

[0041] see figure 1 , Figure 4 As shown, the combined anti-counterfeiting structure consists of a base material layer and a point-shaped, block-shaped or sheet-shaped near-infrared-absorbing ink printing layer and a near-infrared-absorbing ink layer sandwiched between the base material layer and a point-shaped, block-shaped or sheet-shaped near-infrared absorbing ink layer. The sheet-shaped near-infrared non-absorbing ink printing layers between the ink printing layers constitute the first composite layer structure.

[0042] see figure 2As shown, the combined anti-counterfeiting structure consists of a base material layer and a dot-like, block-like or sheet-like near-infrared-absorbing ink prin...

Abstract

The invention relates to an anti-counterfeiting method for combining near-infrared absorbing ink and near-infrared non-absorbing ink. Near-infrared absorbing ink is processed from near-infrared absorbing material and ink binder, and near-infrared non-absorbing ink is processed from near-infrared non-absorbing material and ink binder. The combined anti-counterfeiting method is to use near-infrared absorbing ink to print patterns on the substrate; near-infrared non-absorbing anti-counterfeiting ink printing partially or completely covers the pattern printed with near-infrared absorbing ink to hide the pattern printed by near-infrared absorbing ink; near-infrared identification equipment Use an infrared beam matching the near-infrared-absorbing ink to irradiate and take pictures of the pattern. After the infrared light source illuminates the pattern to be recognized, the pattern printed by the near-infrared-absorbing ink reflects specific near-infrared light. The pattern information is amplified by the lens module and passed through The image is filtered by the filter, and the pattern sensor obtains the coded image, which is converted into corresponding digital information by the signal processor in the near-infrared identification device to identify the authenticity.

Description

technical field [0001] The invention relates to an anti-counterfeiting method for combining near-infrared absorbing ink and near-infrared non-absorbing ink. Background technique [0002] CN200910119710.5 discloses a "covered information invisible coding anti-counterfeiting printing technology". The core constitutes a comprehensive anti-counterfeiting technology. This invention enables the printed dot-shaped information code to be printed on the ticket without leaving any printing traces, which changes the traditional anti-counterfeiting method and uses a special identifier to read it. True is true, false is false, and true and false cannot be confused. The gist of this technical solution is: the cover-type information invisible coding anti-counterfeiting printing technology is to use a special paint to cover the anti-counterfeiting information coding on the plane ticket and realize the ticket printing at the same time. It is designated for exclusive use by the inquiry agen...
