The cigarette bag printing and printing process common way Raiders

1, sweep gold

A process between bronzing and gold printing is characterized by its high speed and low cost, and it can achieve the desired results regardless of the thickness of the image and the size of the area. Gold powder color is also varied, such as gold, silver, red gold, red copper, green, brown, lemon, peacock blue, etc., also have different granularity, showing different visual effects. In foreign countries, there is currently a kind of gold powder that has the effect of imitating diamonds. The gold powder has four particle sizes and 10 colors. It can make the whole graphic text appear as a set of diamond patterns under the illumination of light, reflecting the uniqueness of multicolored light. effect. Representative cigarette packs: Red "Huangshan".

2, holographic hot stamping

Laser holograms are based on the principle of laser interference, using the method of spatial frequency coding. Because laser holograms were pleasing to the eye, with distinct layers, vivid images, varied optical transformation effects, and high information and technical content, they were used in the field of security in the 1980s. The latest OVD technology has been clearly distinguished from the widely used HOLOGRAM holograms, which have machine identification capabilities. The mechanism of holographic bronzing is that the hot melt adhesive layer and the separation layer on the holographic hot stamping material are heated and melted on the hot stamping device through a heated hot stamping die, and under the action of a certain pressure, the information layer holographic grating of the hot stamping material is applied. The stripe is separated from the PET substrate, so that the information layer of the aluminum foil is adhered to the bearing surface and integrated into a single body to achieve a perfect combination.

There are three types of holographic hot stamping types:

A. Ordinary edition hologram scalding;

B. Special edition holograms are hot;

C. Special version hologram positioning hot. Among them, the third special version of hologram positioning was hot and appeared frequently on high-grade cigarette packs in the past two years. It means that the hologram of the specific part of the holographic anti-counterfeit stamping electro-aluminum is accurately stamped on the hot stamping device to a specific position of the cigarette pack by photoelectric recognition. Holographic positioning hot technology is very difficult, not only requires the printing plant equipped with high-performance, high-precision positioning of hot equipment, but also requires a high-quality special positioning hot stamping of aluminum, the production process must also be strictly controlled in order to produce qualified Cigarette products. Since the positioning stamping mark has a high anti-counterfeiting performance, it is used in occasions such as banknotes and important documents. Representative cigarette packs: Need for "cloud smoke" and "Lotus King".

3, soft paper stamping, positioning hot

Due to the popularity of high-end cigarettes in the form of soft packaging, the gorgeous post-processing technology that has matured on white card paper has also shifted to soft paper. Yunnan Qiaotong Packaging & Printing Co., Ltd. first tried in this area and achieved great success. This process will be hot stamping, pressure convex finished in a process, the product is full of hot gold, graphics, fine, beautiful, non-pressure convex ramp features. However, this process technology is difficult, and the precision requirements for hot stamping, holographic film, and stamping machines are particularly high, and all operating indicators must be very strict. Because of this, it is difficult to imitate and the degree of anti-counterfeiting is high. It represents cigarette packs: "Fu" and Huize "Little Panda".

4, first hot after the printing process

In order to highlight the specific patterns and logos on cigarette packs, in recent years, some printing companies have also launched a new process of stamping anodized aluminum, and then printing patterns on anodized aluminum. The resulting effect makes the subject of cigarette packs more vivid and lively. The key to this process is that the stamping of the galvanized aluminum must be firm. During the printing, the galvanized aluminum must not be pulled back by the printing ink. This will not only affect the quality of the cigarette packs, but also the anti-pulled aluminum will quickly accumulate on the blankets, resulting in the loss of image dots, and in some cases causing partial image printing failures. With the operation of the machine, the electro-aluminum powder will also remain. Transfer to the ink roller system to accelerate the wear of the ink roller. Therefore, this process should be based on the characteristics of printing paper, select the appropriate aluminum, to ensure that the aluminum can be firmly attached to the surface of the paper. On behalf of cigarette packs: soft pack "Guobin", soft blue package "Eight hi", blue "Shilin."

5, micro-embossing process

This process uses a micro-embossed pattern on the aluminum foil paper graphic part to apply various fine lines. The obtained product has the effect of hot stamping and embossing, and the metal texture is very strong. Representing cigarette packs: Soft and hard packs, "Guobin", soft pack "Guobao", soft pack blue "Eight Bakes", and soft pack "Furong Wang".
