The anti-counterfeiting technology used for anti-counterfeit labels for brand protection mainly includes anti-counterfeiting technology, anti-counterfeiting, anti-counterfeiting, anti-counterfeiting, anti-counterfeiting, laser holographic anti-counterfeiting, digital information anti-counterfeiting, biometric anti-counterfeiting, and radio frequency identification anti-counterfeiting. These anti-counterfeiting technologies or classics, or high-tech, are constantly evolving and advancing with the times. We will share with you the production process and application characteristics.
Printing technology anti-counterfeiting technology and its application
Printing technology anti-counterfeiting technology can be divided into plate-making technology anti-counterfeiting technology, printing technology anti-counterfeiting technology, post-press processing technology anti-counterfeiting technology according to the production process. They can be combined with anti-counterfeiting printing materials and can be combined to build a colorful anti-counterfeiting world.
1. Typical plate making technology anti-counterfeiting technology and its application
The more common anti-counterfeiting technology of plate making process mainly includes gravure engraving, refraction molding, holographic original printing, etc. Among them, gravure engraving anti-counterfeiting technology has been widely used in the field of securities such as stamps and currency, and also has good in the field of anti-counterfeiting labels. Application prospects; holographic original printing is generally completed by professional laser holography technology company, and its holographic hot stamping foil, holographic paper/holographic film, holographic transfer film, etc., are widely used in the field of anti-counterfeiting labels.
2. Commonly used printing technology anti-counterfeiting technology and its application
The anti-counterfeiting technology of the printing process can be completed by conventional analog printing, such as engraving gravure printing, imitation metal etching ink screen printing, combined printing, etc., or digital printing, such as variable barcode, Variable-coded printing, etc.; special effects printing, such as 3D raster stereo printing, can also be achieved by combining with pre-press image processing techniques.
Engraving gravure printing, imitation metal etching ink screen printing, three-dimensional printing are relatively classic printing technology anti-counterfeiting technology, until today, in the field of anti-counterfeiting printing is still full of vitality. Digital printing has achieved a pivotal position in the field of information anti-counterfeiting because of its variable information printing. Variable QR code is the most typical application combined with Internet and mobile intelligent terminals. It is mainly used for authenticity inspection and product traceability. .
3. The main post-press processing technology anti-counterfeiting technology and its application
Anti-counterfeiting technology of post-press processing technology is mainly realized by cold hot stamping, three-dimensional hot stamping, holographic positioning hot stamping, cold light source curing, UV compression molding, refractive molding, concave and convex imprinting, laser holographic molding and the like.
Cold stamping and cold light source curing are new technologies that have emerged in recent years. Among them, cold light source curing is usually UV curing.
Cold light source curing is effective in economical, environmentally friendly, curing effects, especially in the process of odor control during curing, so cold light source curing equipment and ink (varnish) have received widespread attention in label production.
The cold light source is combined with water cooling and air cooling to reduce the temperature of UV curing, which can reduce heat by up to 80%, and ensure that the surface temperature of the substrate does not exceed 45 °C. The utility model has the advantages that the cost can be reduced, the production efficiency can be improved, the ink adhesion and the color fading of the printing product can be solved, and the deformation of the substrate can be avoided (the blanching and the ordinary curing can cause deformation of the printing material), the application range is wider, and the environment is more environmentally friendly.
The printed matter was heated and dried, ordinary UV curing and H-UV cold light source curing (Hybrid-UV) technology, and the CO2 emissions in the production process were compared. On the far right is the CO2 emissions from the H-UV curing technology. The leftmost is the CO2 emissions from the traditional light source for heating and drying, and the middle is the CO2 emissions when curing with a common UV light source. It can be seen from Fig. 1 that when the ordinary UV curing technology is used, the CO2 emission is the highest, which is 1.8 times that of the heating and drying; and when the H-UV curing technology is used, the CO2 emission is only 55% of the heating and drying.
From the point of view of the process flow, the use of cold light source curing can also simplify the printing process, making the front and back printing and post-press processing in one go.
In recent years, a new UV compression molding process has emerged. By pressing the concave and convex pattern on the surface of the UV varnish, it appears to have a colorful color effect by the principle of reflection of light. The "molded version" used in the UV compression molding process is a holographic molded film with a fine-milled embossed grain. The process of UV compression molding is as follows: firstly coating UV varnish on the printing ink layer, then covering the holographic molding film with a certain pressure on the UV varnish coating, and after UV curing, removing the holographic molding film. The molded anti-counterfeiting effect can be formed on the surface of the UV varnish.
UV compression molding not only eliminates the traditional laser product transfer and compounding process, but also greatly reduces costs and improves production efficiency. It also avoids the dangers of the rubber compounding process and reduces environmental pollution. Moreover, from the perspective of the finishing effect of the printed matter, the holographic imprinting is directly performed on the surface of the UV varnish, and the obtained laser effect is brighter.
Anti-counterfeiting paper and film and their application
1. Common anti-counterfeiting paper and its application
Common security papers mainly include the following categories.
(1) Watermark security paper, including fixed watermark paper, semi-fixed watermark paper, and non-fixed watermark paper;
(2) Filament yarn and color-encrypted security paper, which are mostly used in cigarette packets, RMB, securities and tickets;
(3) Holographic security paper, mainly including straight coated paper and transfer paper;
(4) RMB security thread security paper, which is divided into thermal type, laser holographic type, metal line or magnetic line;
(5) Special securities anti-copy paper, with full absorption type and aluminum coated protection type;
(6) Secretical paper containing an ultraviolet light inhibitor inside;
(7) Anti-counterfeiting cardboard, commonly used for layered dyed cardboard.
Some ultra-wide-line security anti-counterfeiting technologies are used on some foreign coins and securities. For example, De La Rue's ultra-wide safety line technology used on banknotes in Tajikistan and Fiji is a safety line with a width of 18mm. It is made in paper by a cylinder paper machine, and it can present a complete, transparent and clear window on the paper with metallic luster and fluorescent characteristics.
2. Common anti-counterfeiting film and its application
Commonly used anti-counterfeiting films mainly include non-transfer type anti-counterfeit holographic film (aluminized anti-counterfeit holographic film and transparent anti-counterfeit holographic film) and transfer type anti-counterfeit holographic film (aluminized anti-counterfeit holographic transfer film and transparent anti-counterfeit holographic transfer film). The transfer method of the transfer type anti-counterfeit holographic film includes a composite peeling method, a UV curing method, and hot stamping. Whether it is aluminized film or transparent film, its product types and applications are expanding with the advancement of technology and market demand, especially the cold-hot holographic anti-counterfeiting film used in foreign countries in recent years, the latest cold-blowing technology, holographic The combination of technology and anti-counterfeiting technology has been successfully applied to some product labels.
