Self-adhesive is a batch of anti-counterfeiting
means with a long history, based on self-adhesive, made of self-adhesive form of anti-counterfeiting label. Put the label on the product, it has a good anti-transfer effect. Therefore, it has a wide range of applications. The anti-counterfeiting effect is good because of the printing technology of the self-adhesive anti-counterfeiting label, so which anti-counterfeiting technologies are commonly used in the printing of self-adhesive anti-counterfeiting labels?
There are four main printing technologies for self-adhesive anti-counterfeiting labels:
1. Plano-convex printing and multi-process printing
The large-area color blocks, multi-color sequential continuous tone pictures, messy lines and pattern images, etc., in general high-quality packaging decoration print design, bring certain difficulties to a single printing method. Plano-convex printing is adopted, the pressure of the letterpress machine is increased, the uniformity of the ink is used for color printing in a large area, and the pressure of the flat machine is flat and flexible. The time is short, and the effect is very obvious. In addition, for higher and messy prints, you can also choose multi-process synthetic printing such as hand, convex, concave and flat, convex, concave and leaky. In other words, the more complicated the printing process, the better the anti-counterfeiting effect of packaging decorations with higher printing difficulty.
2. Multi-color serial printing
is also called multi-color cross-printing, and is mostly printed by letterpress printing machines. In accordance with the requirements of printed matter, after placing partitions in the ink tank, put various colors of ink in different partitions separately. Due to the cascading effect of the ink rollers, the adjacent inks are mixed and transferred to the printing plate. If this printing technology is used, multiple colors can be printed at a time, making the printing base soft. Since it is difficult to see the placement distance of the groove partition from the printed matter, the anti-counterfeiting effect can also be expected. If this technology is used for large-area shading printing, the anti-counterfeiting effect will be more prominent.
3. Gravure technology
This kind of printing technology has both a protective effect on paper and an anti-counterfeiting function. The main stock is the photo. There are two types of gravure printing according to the plate making method. The anti-counterfeiting effect of gravure printing is outstanding. Contact anti-counterfeiting technology. Some printing anti-counterfeiting inks have larger pigment particles and require a thicker ink layer. The gravure printing has a stronger texture. The connection between the two can play a two-layer anti-counterfeiting and decorative effect. For example, the use of fluorescent ink in gravure printing not only guarantees the micro-convex feel of gravure printing, but also guarantees the application requirements of fluorescent ink, and guarantees the know-how prevention function of both.
4. Laser holographic iris printing
The product is illuminated by a 45-degree point light source, which can produce a colorful rainbow-like effect, and the image has a strong three-dimensional effect, which is deeply loved by consumers. It is called the 21st century inkless color printing by some people of insight. At present, the cold press coating method and the direct heating hot water printing film method are used. The plate-making technology of this technology is rather chaotic and difficult, so only a small number of domestic manufacturers can produce it, which has an anti-counterfeiting effect. It is worth mentioning that in holographic photography, the laser light source is used in the shock-proof room to obtain the amplitude information and phase information of the phenomenon light wave in a short time, and each particle of the phenomenon is formed by the optical stem and principle to form all the information. In the process of plate making, the small air activity in the room will change the color of the hologram, so two unified hologram plates will not be made in any case.
The above content is the commonly used anti-counterfeiting technology of self-adhesive anti-counterfeiting label printing as we know it today. Product companies can also express their own needs when choosing anti-counterfeiting labels, and anti-counterfeiting companies will also design according to customer needs and so on.
