What is the difference between UV laser marking and inkjet marking? Which is more worth buying

Logo is an important feature that reflects a good product, such as food packaging, with logo, production date, place of origin, raw materials, barcodes, etc., so that consumers can better understand this product and increase consumption when purchasing Confidence of the users, but also can improve the brand awareness. So how did the pictures and texts of these packages come to be? What kind of effect can it have on anti-counterfeiting? Let's analyze it together.

What is the difference between UV laser marking and inkjet marking? Which is more worth buying

At present, most of the text patterns of many packaging or product parts on the market use inkjet marking or laser marking. An increasingly popular marking method. 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?

What is the difference between UV laser marking and inkjet marking? Which is more worth buying

In order to answer the above questions well, you can take an in-depth look at UV laser marking and inkjet marking, and analyze from the function, demand, marking effect and price to help you choose a more suitable marking machinery product for you.

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 ultraviolet laser also adopts a non-contact processing method. After being focused by laser scanning, the ultra-fine laser light speed is like a tool, which can gradually remove the surface material of the object. Touch the surface of the object to be smooth and flat, and there is no residue. (purified into gas), and the temperature during the marking process is very low, if you touch the marked position, you will find that the temperature is very low, almost negligible. Without knowing it, there are still many people who worry that the laser power is so high that the UV laser plastic marking will be deformed or will the graphics and texts turn yellow and black? As shown in the figure below, from the marking template, the original shape has not changed, and the font is very clear.

Advantages: UV laser marking can make the mark indirectly engraved on the surface of the product, which can be either scribing or dot matrix. The visual effect is unique and clear and permanent. It cannot be erased and changed, and it is not affected by 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, it is easy to cause damage to the eyes if you work for a long time. Therefore, you must operate according to the operation instructions, and non-operators cannot use it at will.

Inkjet marking machine

A high-speed pneumatic inkjet marker is provided with an atomizing air inlet and an ink inlet on both sides of a mixing valve body, and a needle valve switch air inlet is arranged on the switch control valve body to mark objects and generate speed, It's also clear on paper objects.

Advantages: Compared with laser marking personnel, inkjet marking does not have such high requirements for operation. It can be easily used with a few simple drills and does not require strict training.

Disadvantages: Inkjet marking needs to consume a certain amount of toner in the marking process. If it is mass-produced, it will cause high processing costs, and marking on plastic, glass, leather, etc. under certain conditions, such as moisture, air acidity , touch, high temperature, etc., the mark is easy to fall off, and it is easy to erase and change when just marking, so the general inkjet marking anti-counterfeiting effect is not good.

What is the difference between UV laser marking and inkjet marking?

1. Work efficiency

Ultraviolet laser marking adopts laser marking, the pulse repetition frequency is 1-150KHz, and the high peak power 355 nm ultraviolet laser output is obtained. The ink jet printer adopts on-line production without pause, and the production efficiency also reaches the industrial 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 will not produce any consumption in the middle. It adopts an etching process, and the pictures and texts 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 raw materials for ink cartridges. The cost price of ink cartridges is inherently high. If it is used for mass production and marking in enterprises, it will increase production costs and reduce product profits.

3. Data compatibility

Ultraviolet laser marking uses a remote control computer, which has powerful data processing capabilities and a powerful communication interface to obtain various content of a large amount of information, and the proofing text can be replaced at will. The inkjet coding is only controlled by a single chip, and the data processing capability is limited.

4. Save environmental protection

The UV laser adopts non-contact marking, and the marking process has no consumption and no harmful chemical substances to the human body and the environment. Inkjet coding requires toner raw materials, which are easy 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 recent years. It has a certain foundation for laser applications, reliable performance, high long-term work stability, 24/7 industrial-grade applications, and is suitable for long-term pipeline operations. If the inkjet marking is operated for a long time, the nozzle is easy to be blocked, and the paint needs to be replaced in the middle, which cannot meet the long-term operation standard.

Epilogue

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 it is an individual, the marking requirements are not very high, such as paper type product, inkjet marking is a good choice. If the enterprise wants to operate in a long-term flow, the process requirements are relatively high, and there are many types. Ultraviolet laser marking is recommended.
