Logo is an important feature that reflects a good product, such as food packaging, with logo, production date, place of origin, raw materials, barcode, etc., allowing consumers to better understand this product and increase consumption when buying The confidence of the audience can also increase the brand’s visibility. So how are these packaging graphics formed? What effect can it have on anti-counterfeiting? Let's analyze it together.
At present, most of the text patterns of many packaging or product parts on the market use inkjet marking or laser marking. The former is widely used, while laser marking has become more sophisticated in recent years. A marking method that is becoming popular. Faced with these two marking methods, many people have questions. Which product to choose for marking? What is the difference between UV laser marking and inkjet marking? Why is UV laser marking an upgrade of inkjet marking?
In order to answer the above questions well, you can take a closer look at UV laser marking and inkjet marking, analyze the function, demand, marking effect and price, and help you choose a more suitable marking machine product.
UV laser marking machine
The wavelength of the ultraviolet laser is 355nm, the pulse width is narrow, the spot is small, the speed is fast, and the peak value is high. The minimum line width can reach 0.04mm. Through remote computer control, it can be accurately processed when processing the object.
The UV laser also uses a non-contact processing method. After laser scanning and focusing, the extremely fine laser light speed is like a tool, which can gradually eliminate the surface material of the object. Touch the surface of the object by hand to be smooth and flat, and there is no debris at all. (Purified into gas), and the temperature is very low during the marking process. If you touch the marked position, you will find that the temperature is very low, which is almost negligible. Without understanding, there are still many people who are worried that if the laser power is so high, the UV laser plastic marking will be deformed or the graphics will turn yellow and black? As shown in the figure below, from the marking model, the original shape has not changed in any way, and the font is very clear.
Advantages: UV laser marking can indirectly mark the mark on the surface of the product. It can be scribed or dot matrix. The visual effect is unique and clear and permanent. It cannot be erased and changed, and it is not affected by the external objective anti-counterfeiting effect. Anti-counterfeiting has a special meaning.
Disadvantages: The ultraviolet light is very strong. If you do not wear special glasses for work and work for a long time, it is easy to cause damage to your eyes. Therefore, you must follow the work instructions during operation, and non-operators cannot use it at will.
Inkjet marking machine
A high-speed pneumatic inkjet marking device, with atomizing air inlets and ink inlets on both sides of the mixing valve body, and needle valve switching air inlets on the switch control valve body to mark objects and generate speed, It is also clear on paper objects.
Advantages: Inkjet marking is relatively less demanding than laser marking personnel. As long as a few simple drills can be easily used, no strict training is required.
Disadvantages: Inkjet marking needs to consume a certain amount of toner during the marking process. If it is mass-produced, it will cause high processing costs. In addition, marking on plastic, glass, leather, etc. under certain conditions, such as moisture and air acidity , Touch, high temperature, etc., the mark is easy to fall off, and it is easy to erase and change when it is just marked, so the general inkjet marking has poor anti-counterfeiting effect.
What is the difference between UV laser marking and inkjet marking?
1. Work efficiency
Ultraviolet laser marking uses laser marking, pulse repetition frequency 1-150KHz, high peak power 355 nm ultraviolet laser output, fast speed, through remote computer technology settings, can achieve fine marking standards. The ink jet printer adopts on-line production without pause, and the production efficiency has reached the industry standard. However, some ink jet printers occasionally have ink blocking the nozzles, which affects the production process.
2. Cost saving
The non-contact marking used by the ultraviolet laser does not cause any consumption in the middle. The etching process is adopted, and the graphics and text are not easy to change or fall off, which has a good anti-counterfeiting effect to a certain extent. Inkjet marking requires the matching of ink cartridge raw materials, and the cost of ink cartridges is inherently high. If it is used for mass production marking of enterprises, it will increase production costs and reduce product profits.
3. Data compatibility
Ultraviolet laser marking adopts a remote control computer, which has powerful data processing capabilities and a powerful communication interface to obtain a large amount of information. The proofing text can be changed at will. Inkjet coding is only controlled by a single-chip microcomputer, and the data processing capacity is limited.
4. Saving and environmental protection
The UV laser uses non-contact marking, there is no consumption in the marking process, no harmful chemicals to the human body and the environment, and it meets the standards of GB7247-87; GB10320-88, which is an environmentally friendly high-tech product. Inkjet coding requires toner raw materials, which tend to fade over time and cause certain pollution to the environment.
5. The equipment is stable
With the rapid development of science and technology, the technology in the laser field has developed rapidly in the past few years. It has a certain foundation for laser applications, reliable performance, high long-term stability, 24/7 industrial-grade applications, and long-term assembly line operations. If inkjet marking is operated for a long time, the nozzles are easy to be blocked and the paint needs to be replaced in the middle, which cannot meet the long-term operation standards.
Conclusion
Now it is not difficult to distinguish the relationship between the two! In terms of work efficiency, cost saving, data compatibility, anti-counterfeiting effect, and stability, UV laser marking is incomparable to traditional inkjet marking. In terms of cost, UV laser marking machines generally cost thousands or even tens of thousands, while inkjet marking machines generally cost thousands of dollars. If the individual has not very high marking requirements, such as paper type Products, inkjet marking is a good choice. If it is a long-term streamlined operation of an enterprise, which requires relatively high technology and has many types, UV laser marking is recommended.
