Logo is to reflect the important characteristics of a good product, such as food packaging, logo, production date, origin, raw materials, bar code, etc., so that consumers can better understand the product, in the purchase can increase consumer confidence, but also can improve brand awareness. So these packaging graphics and text is how to form? On the anti-counterfeiting can play what kind of an effect? Let's analyze together.
At present, most of the text patterns of many packaging or product parts on the market are inkjet marking or laser marking. The former is widely used, and laser marking is a marking method that has gradually become popular with the precision of the process in recent years. Faced with these two marking methods, many people have questions about which product to choose for marking? What is the difference between ultraviolet laser marking and inkjet marking? Why is ultraviolet laser marking an upgrade of inkjet marking?
In order to answer the above questions well, we can look at UV laser marking and code spraying marking in depth, and analyze the functions, requirements, marking effects and prices to help you choose more suitable marking mechanical products.
UV laser marking machine
Ultraviolet laser wavelength of 355nm, narrow pulse width, small spot, fast speed, high peak, can achieve the minimum line width of up to 0.04mm, through remote computer control, in the processing of objects can be accurately processed.
At the same time, the ultraviolet laser adopts 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 with hands to be smooth and flat, and there is no residual debris (purified into gas) when looking at it. Moreover, the temperature during marking is very low. If you touch the marked position, you will send out a very low temperature point, which is almost negligible. Without understanding, there are still many people who worry that the laser power is so high that the UV laser plastic marking will deform or the text will turn yellow and black. As shown in the figure, 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 both scribed and dot matrix. The visual effect is unique and clear and permanent, cannot be erased and changed, and is not affected by external objective anti-counterfeiting effect. It has special significance for anti-counterfeiting.
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 when operating, and non-operators cannot use them at will.
inkjet marking machine
The invention relates to a high-speed pneumatic inkjet marker, which is provided with an atomized air inlet and an ink inlet on both sides of a mixing valve body, and a needle valve switch air inlet is provided on a switch control valve body to mark objects, generate a speed, and are also clear and clear on paper objects.
Advantages: inkjet marking relative to laser marking personnel operation is relatively less demanding, as long as a simple exercise a few times can easily get started, do not need to go through strict training.
Disadvantages: Inkjet marking needs to consume a certain amount of toner in the marking process. If it is produced in large quantities, it will cause high processing costs. Moreover, under certain conditions such as moisture, air acidity, touch, high temperature, etc., the marks are easy to fall off and are easy to erase and change when 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
UV laser marking using laser marking, pulse repetition frequency 1-150KHz, high peak power 355 nm UV laser output, fast, through the remote computer technology settings, can be very good to achieve fine marking standards. The ink inkjet printer adopts online production without pause, and the production efficiency also reaches the industrial standard. However, some ink inkjet printers occasionally have ink blocked the nozzle and other situations, affecting the production process.
2, cost savings
UV laser using non-contact marking, the middle will not produce any consumption, the use of etching process, the text is not easy to change or fall off, to a certain extent, play a good anti-counterfeiting effect. Inkjet marking requires the matching of ink cartridge raw materials. The cost price 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
UV laser marking using remote control computer, with powerful data processing capabilities, a powerful communication interface to obtain a variety of large amounts of information content, proofing text can be replaced at will. Inkjet coding is only controlled by single chip microcomputer, and the data processing ability is limited.
4. Saving environmental protection
The ultraviolet laser adopts non-contact marking, the marking process does not have any consumption, and there are no harmful chemicals to the human body and the environment, which meets the GB7247-87;GB10320-88 standards, it is an environmentally friendly high-tech product. Inkjet coding requires toner raw materials, which are easy to fade over time and cause some pollution to the environment.
5. Stable equipment
With the rapid development of science and technology, the rapid development of laser technology in recent years, the laser application to master a certain foundation, reliable performance, long-term work stability, 24/7 industrial applications, suitable for long-term operation of the assembly line. If inkjet marking is operated for a long time, the nozzle is easy to be blocked and the coating needs to be replaced halfway, which cannot meet the long-term operation standard.
Conclusion
Now it is not difficult to distinguish the relationship between the two! From the point of view 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 are generally thousands or even tens of thousands of dollars, while inkjet marking machines are generally thousands of dollars. If individuals are not very demanding on marking, such as paper products, inkjet marking is a good choice. If it is a long-term flow operation, the process requirements are relatively high, and there are many types, it is recommended that UV laser marking.
