Guide: The laser jet printer jets a permanent mark that cannot be wiped off. It is instantly vaporized directly on the surface of the object by laser. It can be visually distinguished without any aids and is easy for consumers to identify. And no consumables, maintenance is more convenient. The laser printer has broken through the normative and unitary nature of traditional ink coding technology, creating a new way of spraying, highlighting the characteristics of the product and the differences of the brand, and enhancing the competitiveness of the product in the increasingly fierce market. At the same time, it provides a powerful tool for shortening the product upgrade cycle and flexible production.

First, laser marking is generally achieved in three ways:

Removal of surface material marking
Remove surface coating or coating
Color change marking
The first two of these three methods can leave a certain depth (≤0.3mm, depending on the material) dent on the surface of the product, and the third is because the material itself will change color after chemical reaction after heat. . Therefore, the laser marking has a permanent and extremely strong anti-counterfeiting effect.

Laser coding technology uses ablation and engraving to remove or melt materials, and it provides high quality and permanent code in a short period of time compared to coding with inkjet technology or printing and labeling. This technology provides manufacturers with a low-cost, efficient way to code and mark.

Laser coding technology is expected to become a popular technology in the packaging industry compared to other coding and commodity marking technologies. What characteristics make laser technology continue to spread? The advantages of laser coding are: no need for consumables (eg ink, solvent), low maintenance costs, short system downtime, low environmental pollution (due to the lack of ink), wide range of materials that can be coded, and easy system integration.

Second, the current laser marking machines commonly found in the domestic market are roughly divided into the following two types:

A. Laser printer
It is a kind of marking equipment matched with various product packaging production lines. The marked products are moving without stopping on the production line, laser continuous coding (marking), long-term operation and maintenance-free, and it belongs to environmental protection new-generation products.

The device can be used to mark various online sports products or materials such as paper, plastic, glass, leather, wood or metal materials by using different lasers (originally imported long-life CO2 lasers or YAG continuous lasers). Ink coding marks the function of date, batch number, time and text in dot matrix on various products, without ink, pollution, and running cost.

B. High-speed scanning galvanometer laser marking machine
It is the most advanced laser marking system at home and abroad. This system has the characteristics of fast scanning speed, high repeatability and good durability. It is different from the workpiece that the laser printer is moving online. The laser marking machine is mostly used for stationary materials. Labels such as paper, plastic, glass, leather, wood or metal materials, date, batch number, time, text and various logo patterns are vectorized.

With the continuous development of science and technology, laser inkjet printers have become the development trend instead of inkjet printers. In recent years, several domestic companies specializing in the production of inkjet printers have developed nozzle laser printers and galvanometer laser printers.

China has developed and produced a series of laser printers based on ordinary laser printers. It is based on more than 20 years of experience in laser technology, and laser jet printers developed from accessories from Germany and the United States have been widely used. Bottled water, beverages, food, pharmaceuticals, personal skin care products, daily necessities, tobacco, wine and other industries. After years of continuous improvement and improvement, the new generation of RGV laser printers has more complete functions, more reliable performance, more stable operation and more convenient installation.

The laser jet printer jets a permanent mark that cannot be wiped off. It is instantly vaporized by the laser directly on the surface of the object. It can be visually distinguished without any aids and is easy for consumers to recognize. And no consumables, maintenance is more convenient. The laser printer has broken through the normative and unitary nature of traditional ink coding technology, creating a new way of spraying, highlighting the characteristics of the product and the differences of the brand, and enhancing the competitiveness of the product in the increasingly fierce market. At the same time, it provides a powerful tool for shortening the product upgrade cycle and flexible production.

With the continuous development of electronic technology, laser and computer technology are organically combined, and users can realize laser ejection output by programming on a computer. It can also eject a clear mark on several materials or on irregular surfaces, with the unique effect of “one dozen double mark” or “riding mark”, which is not easy to imitate. The laser can form a very thin beam with a minimum line width of 0.1 mm on the surface of the material, creating a wide space for precision machining and anti-counterfeiting. Not only can you spray complex text, graphics, images, light-transparent buttons, trademark design, barcodes, QR codes, product serial numbers, autographs, etc. Any graphics and text displayed on the screen can be sprayed at the specified time. The surface of the material. Laser coding can also improve the appearance of the product and the brand name effect, and enhance the market competitiveness of the product.

The laser printer can print random code or anti-counterfeiting code. It can also make a separate code for each bottle or every small bottle cap. It can be directly recognized, fast and easy, and can also price, promotion and other information. Printing on the packaging of the wine can effectively control the sales price of the wine and prevent market fluctuations.

High-quality CO laser printer can also print various unchangeable graphics, texts, numbers and other information on high-speed and clear packaging in various materials (such as wine bottles, caps, etc.); in products or packaging Print special marks (graphics, text, code), or use the special function of laser jetting to effectively prevent the circulation of counterfeit and counterfeit products and cross-regional sales and stocks; print numbers and barcodes on product packaging and carton packaging. Sending information to the local area, and connecting to the database system, can also achieve flow tracking and tracking tracking of distributors across regions, which is beneficial to protect the legitimate interests of manufacturers.
