The Use of Packaging Anti-counterfeiting Printing Materials for Colour Printing Packaging
Color printing packaging: Packaging anti-counterfeiting printing materials are diverse, but mainly paper and ink have special requirements.
Anti-counterfeit paper: Color printing packaging: In the papermaking process, various anti-counterfeiting technologies are used to produce various anti-counterfeiting papers, which are used to print packaging labels or packaging paper to achieve the purpose of anti-counterfeiting. At present, there are mainly the following paper anti-counterfeiting technologies.
1. Laser holography technology: The laser holographic pattern is directly produced on the paper using the laser holographic technology to produce the laser hologram anti-counterfeiting paper.
2. Watermarking technology: This technology uses a watermark roll with engraved lines to press the paper surface during the formation of the paper web, when the paper pages have just been interwoven and still contain a certain amount of moisture, so that part of the wet paper is shifted and the fiber density is different. Various graphics, numbers or text watermarks with light and dark textures.
Some companies also file their special watermark patterns with specific management departments. At the same time, paper companies no longer produce the same specific-purpose paper for other users. Although this has increased the cost of paper, it has also greatly increased Counterfeiting costs, and its anti-counterfeiting effect is ideal.
3. Special additives technology:
Add colored filaments. Colored fiber filaments are colored fibers that are distributed on the surface of paper and have different colors from the paper. There are certain differences in color, length, thickness, degree of embedding, and distribution position. Join the safety line Color printing packaging: The safety thread refers to the opaque long metal or plastic narrow bands embedded in the paper in whole or in part, which often contain transparent or holographic microtext information, magnetic information, etc. The production of the security thread requires a high level of papermaking technology and a complex process, especially the window-opening (intermittently exposed) security thread. This kind of security thread is embedded in the paper and the other is exposed on the surface of the paper, which is quite difficult to forge. In recent years, a thermal safety thread has been introduced. It is pink and opaque at room temperature. When the temperature reaches 37~C with a finger, the microprinted text will appear locally. Add fluorescent fiber In the papermaking process, the colorless fluorescent fiber strips are added to the pulp according to the proportion. This kind of paper can display fluorescent fiber strips under the excitation of ultraviolet rays, which can be recognized by the public. Add trace additives Color printing packaging: using the principle that organisms have a specific reaction of the anti-element body, add a very small amount of anti-element to a certain part of the pulp or paper. When detecting, use the corresponding specific antibody to bind to it, and distinguish the authenticity by the presence or absence of the reaction of the markers such as color development and fluorescence.
4. Chemical technology: Special compounds are added to the pulp or when sizing on the surface of the paper to make chemically encrypted paper, which can develop color or fluorescence when coated with specific chemical reagents.
5. Special equipment technology: Special equipment is used in papermaking, such as ionic media special anti-counterfeiting paper, and relying on a large-scale heavy ion accelerator controlled by the state to integrate ion microporous technology and papermaking technology into one system to produce super-energy
ionic media special anti-counterfeiting paper. For example, laser anti-counterfeiting technology and special equipment can be combined with paper making to make laser anti-counterfeiting paper. For more details please visit also: http://www.biotechpackages.com/
