Ink anti-counterfeiting packaging technology is an anti-counterfeiting packaging technology developed after printing anti-counterfeiting packaging. This anti-counterfeiting package prints inks with special properties onto the package, and the user (consumer) can use the simple method (such as illumination, heating, etc.) to identify the authenticity when purchasing the product. Ink anti-counterfeiting packaging is the most popular and popular anti-counterfeiting packaging technology. In particular, it is widely used in paper container packaging products, and the identification methods are all described on the package.
It is a relatively advanced first-line anti-counterfeiting packaging technology. It has the characteristics of high imitation difficulty, high cost of product development input, and difficulty in breaking. Many anti-counterfeiting packagings are encrypted on the material formula and combined with special processes. Therefore, it is difficult for the counterfeiters to copy them in a shorter period of time, which is more reliable than printing anti-counterfeiting packaging. The identification information of ink anti-counterfeiting packaging is reversible and irreversible. Reversible refers to reusable and multiple recognition; irreversible refers to one-time identification, and once it is recognized, its anti-counterfeiting function is destroyed and the anti-counterfeiting effect is lost. There are many types of anti-counterfeiting inks commonly used. For example, optically variable inks, magnetic inks, heat sensitive inks, conductive inks, and the like. Regardless of the type of anti-counterfeiting ink, it is specially processed in its distribution ratio and manufacturing process. After printing on the package, consumers can receive special signals according to their instructions, by stimulating their identification parts (marks, marks, labels, etc.) by simple means (such as illumination, heating, magnetic contact, etc.). Thereby achieving (judging) anti-counterfeiting purposes.
To use ink technology reasonably in anti-counterfeiting packaging and achieve the desired anti-counterfeiting effect, there are many factors to consider, including the choice of printing methods, the selection of printing presses, the processing of printed parts, the use of ink base materials, printing costs and Enterprise technology level and so on. Specifically, the ink for anti-counterfeiting packaging refers to a printing ink which has a certain amount of special substances in the preparation of printing ink in order to make the product after packaging printing have a certain anti-counterfeiting ability, and exhibits special performance under certain conditions after printing. . The variety of special substances has formed a variety of inks for anti-counterfeiting packaging.
Thermal ink
The pigment of the heat-sensitive ink can change color according to the change of temperature, and different temperatures show different colors. There are many kinds of pigments which can exhibit thermochromic properties, and there are commonly used crystal structure change types, thermal decomposition type, and crystal transfer type. There are many types of thermal printing inks currently on the market, which basically meet the requirements of thermal discoloration. However, the characteristics of the different types are quite different. For example, the liquid crystal type ink has a good discoloration degree, the metal chromium salt type ink has a strong light resistance, the fuel type printing ink has a bright color, and the packaging and decoration effect is good.
Magnetic ink
The pigment used in the magnetic ink is a magnetic material, and commonly used is triiron tetroxide, etc., the residual magnetic property is relatively high, the continuous material is generally an alkyd resin, and other pigments may be added to the magnetic ink to obtain inks of various colors. . Magnetic inks are used in anti-counterfeiting packaging to form a secret anti-counterfeiting function. It is printed with magnetic ink in a certain part of the package and can be detected by special means to form a secret anti-counterfeiting.
Fluorescent ink and phosphorescent ink
The fluorescent ink is made by dissolving the work light material in the corresponding resin. The particles of fluorescent pigments are generally large, and there are many types of binders. Different binders will produce different fluorescence. When using fluorescent inks, it should be ensured that there is sufficient agronomy, and the ink layer on the printed products should be thicker. This will ensure a satisfactory fluorescent effect. The printed products printed with fluorescent inks are brightly colored and have a good decorative effect. Under the action of visible light and ultraviolet rays, they can emit sparkling light.
Of course, every anti-counterfeiting ink loses its novelty over time, but as long as we use it properly, it will extend its useful life. There are two main methods for combining anti-counterfeiting inks. There are two main methods for using anti-counterfeiting inks. One is to combine the characteristics of two or more anti-counterfeiting inks to form a new anti-counterfeiting ink. The second is to use characters or The pattern is printed with two or more types of security inks. If a bar-like pattern is printed, the strip of the pattern can be printed with a magnetic anti-counterfeiting ink, and the pattern of the pattern is printed with heat per ink. Obviously, this will increase the technical content of the anti-counterfeiting ink. If you can use this composite method online, you will get better anti-counterfeiting effects.
