The near-infrared absorption security ink is made by adding one or several kinds of near-infrared absorbing materials to the ink, and the near-infrared absorbing material is an organic functional dye. It has absorption in the near-infrared region, the maximum absorption wavelength of 700nm ~ 1100nm, and the oscillation wavelength falls in the near-infrared area, because the near-infrared absorption ink absorbs infrared light, such as in some parts of the printed product with this ink, without any Traces, but under the detection instrument, the corresponding signal or dark picture can be observed.
The near-infrared absorbing material is an organic polymer material, and its material is synthesized at a high temperature. The production and processing process is complicated, and the technical difficulty is high. The production cost is high. Therefore, the near-infrared absorbing anti-counterfeit ink has high temperature resistance, stable light resistance, good anti-counterfeit effect, and high imitation efficiency. .
First, the application of near-infrared absorption security ink Infrared security ink advantages: strong anti-counterfeiting, technical difficulty, easy to use, almost free from any printing conditions. It can be printed by any printing method and is suitable for security printing of bills, securities, trademarks, etc.
When the near-infrared absorption security ink is used alone, it can be printed with any anti-counterfeiting pattern, one-dimensional barcode, and two-dimensional barcode without being limited by any printing conditions.
The use of inks for infrared (wavelength range 700nm ~ 1500nm) have different absorption characteristics can also be matched to make non-absorbing infrared security ink and near-infrared absorption security ink. Non-absorbing infrared security inks are printing inks that do not absorb near-infrared rays. When used, it can be composed of a pair of near-infrared absorbing ink and non-absorbing infrared anti-counterfeiting ink. The anti-counterfeiting ink or the information printed by the near-infrared absorption security ink is hidden under the non-absorbing infrared anti-counterfeiting ink, so the anti-counterfeit function is more concealed, the anti-copy function is stronger, and the anti-counterfeiting effect is better.
The two-dimensional bar code printed by the near-infrared absorbing security ink is colorless, and a special speech recognition pen can be used to read the anti-counterfeit information, successfully solving the problem that the two-dimensional bar code can be read and prevented from copying.
Second, near-infrared absorption security ink identification 1. Volkswagen first-line identification: near-infrared absorption filter identification through the filter can see the general pattern of near-infrared security printing ink printing, identification is simple and convenient, low cost, the public is easy to identify.
2. Second-line general equipment: portable infrared monitor, inspection team identification through the portable infrared monitor can read near-infrared absorption security ink printed fine patterns, such as two-dimensional coding patterns.
3. Voice Recognition: The intelligent voice recognition pen clicks through a dedicated voice recognition pen to read the information of the near-infrared anti-counterfeiting ink and quickly identify it. It is simple and convenient, and the correct rate is high.
