Tobacco bag ink anti-counterfeiting technical knowledge

Ink not only can complete one of the basic materials for printing, but also has been given a lot of unique properties, making it play a huge role in the security of cigarette packs.

1, fluorescent ink anti-counterfeiting technology

Fluorescent ink anti-counterfeiting technology is a method of printing and packaging with fluorescent ink to prevent counterfeiting. With the pattern printed with fluorescent ink, the light disappears immediately after the ultraviolet light is turned off. Anyang Cigarette Factory used this technique on the special red-flavored “Red Flag Canal” cigarette pack developed in 1997. If it is observed under the UV light of the detector, it can be seen that there is a round of red day spray on the “Red Flag Canal”. And out.

2, luminous ink anti-counterfeiting technology

Luminous ink anti-counterfeiting technology uses ink with light absorption, light storage, and light-emitting functions to print cigarette packs. Consumers can also see patterns or texts in the dark. For example, the "Gutian" packet of cigarettes from the Longyan Cigarette Factory is visible under the night light.

3, DNA ink anti-counterfeiting technology

DNA ink anti-counterfeiting technology is printed with DNA ink. The uniqueness of DNA determines that the print has an independent identity. When the password is introduced into the product, the non-biological gene marker is given. In addition to imitating goods, commodity counterfeiters must imitate the same DNA as the cryptographic marker DNA. Theoretically, the latter counterfeiting is impossible. At present, this anti-counterfeit technology has been applied to the "Panda", "Rose King" and "Yellow Crane Tower" cigarette packs of the times.

4, temperature change ink anti-counterfeiting technology

Temperature change ink anti-counterfeiting technology is that when the lighter flame and other heat sources near the cigarette bag at a specific location or pattern text, its pattern text changes. The small four-square block around the lion's head on the "Red Lion" cigarette pack produced by the Xiamen Cigarette Factory is printed with a temperature change ink. When the temperature rises, the color of the small squares will become lighter and will be restored when the temperature is restored.
