Analysis: cigarette bag anti-counterfeiting technology

While the Chinese cigarette industry has been developing steadily, counterfeit products have always been a problem for cigarette manufacturers. In 2009, China seized 6.14 billion counterfeit cigarettes. How to prevent the product from being counterfeited? How to ensure that the legitimate interests of cigarette manufacturers and consumers are not infringed by illegal cigarettes? This is where anti-counterfeiting measures come into play.

Some high-end cigarette products can be said to be the ultimate in anti-counterfeiting. There are as many as 10 anti-counterfeiting measures, which can be summarized as follows:

Prepress design anti-counterfeiting

Anti-counterfeiting of pre-press design evolved from the earliest hand-engraved engravings to the current use of computer anti-counterfeiting software for programmatic and custom-made production of patterns. Anti-counterfeit technologies commonly used in cigarette packets include: rainbow shading, embossed shading, gradient shading, floriculture, lace, line width changes, and microtext. It is usually added on the top cover of cigarette packs, and combined with special inks to achieve textured prints with optical touch and optical discoloration. The effect can be comparable to the security lines of banknotes. For example, the miniature Chinese language “Shangao Manmade Peak” adopted by “Municipal·Yuxi”, the soft pack “Lanjiao” of Chengdu Cigarette Factory and the “cloud smoke” of Kunming Cigarette Factory all adopted this technology.

Printing process security

In the printing process, offset printing, screen printing, flexo printing, gravure printing, and other multi-process combinations increase the complexity of the process, making it possible to increase the difficulty of printing cigarette packs and effectively improve the difficulty of the imitation of the products by small-scale manufacturers. At present, most of the high-grade cigarette pack printing is a combination of various printing techniques. The Baisha Group, Hongta Group, Changde Cigarette Factory, General Group and many other products also use a combination printing process.

Supplies anti-counterfeiting

In the anti-counterfeiting of cigarette pack printing, the proportion of consumables for counterfeiting accounts for a large proportion, mainly reflecting the anti-counterfeiting effect through paper and ink. The paper-based anti-counterfeiting technologies mainly include: colored fiber paper, ie, colored fibers or colored small pieces (points) such as red and blue are incorporated into the pulp, or scattered on the surface of the paper before the paper is set. It is fluorescently reflected under ultraviolet radiation, giving the paper a colored fiber that is distinct from the paper itself. For example, the overall outer packaging of “Cloud Smoke (84 Impressions)” is based on brown color and is equipped with a light-laser laser film black cardboard. There are full version of holographic laser pattern paper and local positioning laser pattern paper, such as "a pen" of Qingdao Cigarette Factory and "Liqun" of Hangzhou Cigarette Factory.

The anti-counterfeiting of watermarks is the use of bright and dark lines or graphic text made by changing the density of pulp fibers during the papermaking process. Guiyang cigarette factory's gold medal "Huangguoshu" uses this anti-counterfeiting technology, and its gold pattern has a watermark and dark lines.

The ink-based anti-counterfeiting technology is mainly to add anti-counterfeit materials with special properties in the ink binder, and is processed into special printing inks through special processes. There are: fluorescent inks, multiple thermal inks, chemical reaction inks, laser inks, and multiple mirror imaged color inks to achieve anti-counterfeiting effects through ink color changes. For example, the Yuxi Chinese character in "Yuxi" will have the following changes in color when heated: from dark red to red, and then to light red, the Chinese character color disappears, the background color is displayed, and the original color is restored when it is not heated. Printing color. In addition, there are water anti-counterfeiting and some special pearl, gold sand series ink anti-counterfeiting and so on.

Post-print anti-counterfeiting technology

Post-press security, common laser holographic technology. The rise of the anti-counterfeiting technology effectively achieved the perfect unity of packaging security and packaging decoration. The application of laser holographic technology on cigarette packs has the following forms: laser holographic non-positioning hot stamping technology, holographic printing, positioning holographic printing, laser holographic positioning hot stamping technology and transparent holography and positioning hollowing technology. Among them, the laser holographic positioning hot stamping is currently the main means of cigarette bag anti-counterfeiting applications. Domestic famous cigarette brands such as Yunyan, Hongtashan, Dahongying, and Furong Wang have adopted laser holographic positioning for hot stamping. In addition, holographic positioning hollow technology is to etch a transparent pattern, pattern or text in the fixed position of the aluminized holographic hot stamping foil, and then hot stamping on the packaging. The holographic pattern of the virtual reality illusion has exquisite effect, and the technical difficulty is also High, counterfeiters are difficult to imitate.

In addition to the laser holographic technology, there is a stamping and embossing one-step molding technology (such as the "Red Eagle" of Ningbo Cigarette Factory), two-dimensional embossing technology (such as "a pen" of Qingdao Cigarette Factory), and pattern-printing anti-counterfeiting technology ( Such as Chuxiong Cigarette Factory's blue "guests").

In addition, there are other high-tech science and technology printed smoke labels, such as DNA anti-counterfeiting technology used by the Yellow Crane Tower 1916. There is a metal insert card in the "realm Yuxi" strip box. There are three kinds of detailed anti-counterfeiting query methods on the card, as well as the safe die-cutting method. That is, the anti-counterfeiting label has a die-cutting tool mark on it. When trying to remove it, the label is easy. damage. In addition, there are dual-track images and implicit controls. Under normal viewing angles, it can be seen that the Hongta trademark is displayed on a grey matt horse background pattern; when the cigarette pack is rotated 90 degrees, the background is switched to a colored dragon pattern. Shijiazhuang Cigarette Factory New Shijiazhuang cigarette label, the Three Gorges Cigarette Factory's new ninth-generation clamshell tour of the Three Gorges tobacco label, the bottom of the cigarette label or clamshell printed a bit of a rectangular anti-counterfeiting logo. The new soft panda used thin paper to partially apply oil and hit convex.

In short, under the current situation of counterfeit cigarettes, cigarette packaging and printing companies can only adopt more advanced production techniques and materials, and track and lead the trend of printing development. Only in this way can they produce beautiful and elegant cigarette packs that are more in line with anti-counterfeiting requirements. To be invincible in the increasingly fierce competition!
