In the eyes of mass consumers, labels are just a tool for identifying products and analyzing their main components. In the eyes of brand owners, labels are crucial to products, and they are far greater than what consumers see. . Among the many functions of the label, anti-counterfeiting is an important function that cannot be ignored.
Highly recognized ink anti-counterfeiting
Anti-counterfeiting ink is an important part of the anti-counterfeiting technology system. Anti-counterfeiting ink refers to the ink with anti-counterfeiting function. It is also composed of coloring materials, binders and ink additives, but special anti-counterfeiting materials are added to the ink binder. It is processed by special technology and is a special printing ink. The mainstream anti-counterfeiting inks on the market generally include ultraviolet fluorescent ink, daylight color changing ink, heat sensitive ink, chemical reaction color changing ink, water sensitive anti-counterfeiting ink and the like. Products printed with UV fluorescent inks, illuminated by special anti-counterfeiting fluorescent lamps, will be brightly printed with anti-counterfeit fluorescent inks, showing bright red, orange, yellow-green or green fluorescence, high fluorescence intensity and good printing adaptability. The light disappeared quickly. After the purple light was turned off, the light disappeared instantly. Daylight color-changing inks will appear in the light of daylight. The thermal ink changes color after heating, and the pattern is restored after cooling (as shown in Figure 1), which is a reversible color ink.
The advantage of the anti-counterfeiting ink is that under normal observation conditions, the label is in a normal state, and when anti-counterfeiting is required, the authenticity can be easily and quickly identified by a specific means. However, anti-counterfeiting inks also have fatal shortcomings, because special inks have anti-counterfeiting functions. A large part of the reason is that special inks belong to the scope of national control, and the threshold for purchase is high, that is to say, manufacturers with special inks are less in the market, so Achieve a certain anti-counterfeiting effect. However, at present, anti-counterfeiting inks have been widely used for anti-counterfeiting of various types of labels and packaging. The threshold for purchase has become lower, and even without substantial control, the anti-counterfeiting value is gradually reduced.
Optical anti-counterfeiting technology
Speaking of optical security labels, you can't talk about holographic (or laser) anti-counterfeit labels. Currently, various holographic (or laser) labels on the market are mixed, but not all laser labels can be called optical security labels. All laser tags are anti-counterfeiting. Aside from the purely decorative through-the-ray laser label, we are talking about the optical anti-counterfeit label with a high level of anti-counterfeiting.
The anti-counterfeiting strength of hot stamping labels has been much higher than that of ordinary self-adhesive labels. For example, Yunnan Baiyao, which has just been replaced with a new label in the past two years (as shown in Figure 2), the anti-counterfeiting label on the packaging is a hot stamping label. The label has good reflectivity under the side light, and the color is beautiful. The color of the color of the treasure phase is clear, evenly distributed in the circle, and the pinyin letters outside the circle are clear, and the strokes are uniform in thickness, which is an exquisite hot stamping label. High-resolution, three-dimensional true color, reflective angle discoloration, animated text icons, small house textures, pixel transformations, high-definition co-locations, and pixel characters are all high-level optical anti-counterfeiting technologies.
In addition to the optical technology itself, optical security labels also have many special requirements on materials, such as high temperature resistance. When a general hot stamping label passes through a laser printer, the optical pattern on it will disappear, because ordinary optical hot stamping labels cannot withstand the high temperature of 180 °C, but Suzhou Impression Laser Technology Co., Ltd. can already produce such labels. .
In addition to hot stamping labels, optical anti-counterfeiting labels, as well as self-adhesive labels, transfer paper labels, single-use uncovering labels, fragile paper labels, etc., the superposition of various technologies and processes, so that the anti-counterfeiting strength of the labels can be Further improvement. It can be said that optical anti-counterfeiting technology is the most important member of the tag anti-counterfeiting family.
Although there are many applications, only the ever-evolving technology can get out of the mixed market. No single technology can be changed. Only by constantly exploring and researching can the label truly play the role of anti-counterfeiting.
Printing technology security
The printing technology referred to here refers to the entire process of visual information printing and reproduction, including pre-press, printing, post-press processing and transportation. A high-precision large-scale printing equipment is often expensive. Through the high-level operation of the workers, the printed labels are also bright and colorful, and the lines are even, and there are no low-level errors such as ghosting and disconnection, and the counterfeiters generally do not have The above equipment and technical conditions, so the authenticity can be easily distinguished from the appearance of the label.
Paper security
Anti-counterfeiting paper refers to the general name of special papers with markings or hidden marks (such as patterns, patterns, watermarks, numbers, etc.) on the surface or inside, which are not easy to counterfeit, fake or altered.
Anti-counterfeiting paper is generally divided into fiber paper, anti-counterfeit holographic paper, watermark paper, anti-counterfeiting paper with security thread, etc. Suzhou Impression Laser Technology Co., Ltd. has also developed a unique anti-counterfeiting technology combined with various anti-counterfeiting technology (Figure 3 Shown), which combines fiber lines, security lines, optical technology, etc., plus printable effects, both anti-counterfeiting and aesthetics.
Super line security
For the super line, everyone may not be very strange, but it is rarely used on the label. Although some labels on the market currently use the printing super line, the effect is often not ideal, because the ordinary printing super line is easy. It is imitation, can not achieve the anti-counterfeiting effect, can only achieve a limited decorative effect.
At present, a complex and sophisticated super-line anti-counterfeit label is gradually popularized on the market. This super-wire is obtained by sophisticated calculations using professional equipment and software. The super-line is filled on the trademark or pattern of the label. Coupled with exquisite printing technology, many counterfeiters are discouraged.
