A comprehensive overview of the anti-counterfeiting ink market

concept and principle:

anti counterfeiting ink: ink with anti-counterfeiting performance. Anti counterfeiting ink is an extremely important anti-counterfeiting technology field, which has a wide range of applications and involves many disciplines. It is a special ink with anti-counterfeiting function by adding some special substances into the ink, which is specially developed and applied to the printing of anti-counterfeiting printing products. Its formula and process are confidential and should be strictly managed; Its products should also have the best thermal insulation performance at fixed points, be regularly supplied to the designated manufacturers, and be used by special personnel and machines to strictly prevent proliferation

types of anti-counterfeiting inks:

1) photosensitive anti-counterfeiting inks: inks that can emit visible light under light irradiation. The light here refers to visible and invisible light such as ultraviolet light, infrared light and sunlight

a. UV fluorescent ink: ink that can emit visible light (nm) under ultraviolet (nm) irradiation. Generally speaking, short wave ultraviolet is also an urgent problem to be solved in the field of fire public safety. It excites visible fluorescent anti-counterfeiting printing ink with an excitation wavelength of 254nm, and long wave ultraviolet excites visible fluorescent anti-counterfeiting printing ink with an excitation wavelength of 365nm

b. photochromic ink excited by sunlight: an anti-counterfeiting printing ink that can emit visible light of nm under sunlight. From the perspective of application, this kind of ink changes color due to the action of sunlight. In fact, it also changes color due to ultraviolet radiation

c. infrared anti-counterfeiting ink: an ink made by matching the different absorption characteristics of infrared (nm), which can be detected or recognized by instruments. A pair of substances with different infrared absorption characteristics are added to the ink. Products printed with infrared ink have no reaction under ordinary light, while corresponding signals or graphics can be observed under infrared light detection

2) thermal anti-counterfeiting ink: ink that can change color under the action of heat. It is usually divided into reversible and irreversible thermochromic anti-counterfeiting inks; Usually, the color change temperature is Celsius. Hand temperature color changing anti-counterfeiting ink is a kind of thermal color changing anti-counterfeiting ink, which refers to the ink that can change color under the action of Celsius temperature. The principle of thermochromism is to make physical or chemical changes in the color changing compound under heating. Users should determine the light absorption changes from the body according to their own test samples

3) pressure sensitive anti-counterfeiting ink: ink that can appear color under the action of pressure friction. It is made by adding special chemical reagents or color changing substances to the ink. When the colored or invisible pictures and texts printed with this ink are rubbed and pressed with hard objects or tools, chemical pressure color change or microcapsule rupture will occur, and the dye will leak, resulting in color (red, blue, ink, green, purple, yellow, etc.). You can choose the display color and design the secret mark according to the user's requirements

4) magnetic anti-counterfeiting ink: anti-counterfeiting printing ink made of magnetic powder material as a functional component. It is the most commonly used anti-counterfeiting ink, which is characterized by deep appearance color and simple detection instrument. It is mostly used in ticket anti-counterfeiting

5) optical variable anti-counterfeiting ink: it is made of multilayer optical film flake powder that can produce optical interference as dispersion, and the ink is completely different in color when the light incidence angle is 90 ° C and 30 ° C respectively. This technology is extremely complex and expensive. Few countries can produce it, and it has been used in foreign banknotes

6) anti alteration and anti-counterfeiting ink: an ink that has a chromogenic chemical reaction to the chemicals used for painting. Common types to ensure the safety of staff include anti-counterfeiting fluorescent powder, temperature discoloration powder, anti-counterfeiting fluorescent long and short fibers, UV anti-counterfeiting fluorescent ink, infrared anti-counterfeiting fluorescent ink, anti-counterfeiting thermal ink, heating discoloration and sunlight discoloration ink, etc. (for example, photochromic inks that change color under the sun and UV light, and thermotropic inks that change color at different temperatures.) These anti-counterfeiting products can be widely used in the fields of tobacco and alcohol, food, printing, papermaking, textiles, famous clothing labels and so on, and have unique anti-counterfeiting effects
