Logo is an important feature of a good product, such as food packaging, logo, production date, origin, raw materials, bar code, which enables consumers to better understand the product, increase consumers’ confidence to buy, and also improve the brand recognition.
Then how do the pictures and words on these packages come into being?
What kind of effect can they have on anti-counterfeiting?
So let's do that.
At present, many packaging mostly uses inkjet engraving and UV laser engraving. The former has been widely used in the application, and the latter emerges in recent years and goes more and more popular in engraving process. As to the two methods of engraving, many people have some questions.
What is the difference between UV laser engraving and inkjet engraving?
Which one do we choose to make the engraving effect better?
Why UV laser engraving is the upgrade of inkjet engraving?
In order to answer the above questions, you can have a brief look at ultraviolet laser engraving and inkjet engraving in the range of the function, demand, marking effect and price. Then analyze and choose the more suitable method for your own marking products.
The differences between UV laser engraving and inkjet engraving
1. Work efficiency
Ultraviolet laser engraving machine adopts laser marking with a pulse repetition frequency of 1-150 KHZ to obtain a peak power of 355 nm UV laser output. The high speed can be achieved through the remote computer technology setting, and the fine marking standard can be achieved very well.
Ink jet engraving machine adopts on-line production without stopping, the production efficiency also reaches the industrial standard. But some ink spraying machines occasionally get ink blocking on the nozzles and other circumstances, affecting the production process.
2. Cost-saving
UV laser marking is non-contact, the marking process will not produce any consumption. It adopts laser etching technology, so that the graphics and texts are not easy to change or fall off. To a certain extent, it plays a good role of anti-counterfeiting.
Ink jet marking requires the combination of ink cartridges. The price of ink cartridge is already high. If it is used for mass marking or engraving work, it will increase the production cost and reduce the enterprise’s profits.
3. Data compatibility
UV laser marking adopts remote controlling of computer, which has a powerful data processing capacity, and a powerful system to obtain large amounts of engraving contents. The picture and text patterns can be changed at will.
Ink-jet marking is only controlled by single chip microcomputer with limited data processing capacity.
4. Environment-saving
There are no contacts and no consumption in the process by laser engraving. Therefore, there are no harmful chemicals to produce.
Ink-jet printing requires toner material, which is easy to fade over time and produces certain pollution to the environment.
5. Stable equipment
With the rapid development of science and technology, the laser technology has been developed rapidly in recent years. It already has a good foundation of application,a reliable performance. And it is suitable for a long-term and automated production line operation.
While the ink-jet marking technology couldn’t make it. After a long-time operation, the nozzles on the ink jet machine are easy to plug, the ink cartridges have to be replaced in midway. That can not reach the need of long-term and automated operation.
Conclusion
It's not hard to tell the difference now! UV laser engraving is unsurpassable by traditional ink-jet engraving in terms of work efficiency, cost saving, data compatibility, anti-counterfeiting effect and stability.
In terms of cost, UV laser marking machine generally save thousands or even tens of thousands. And if the enterprise needs a long run production line, a variety of uv laser marking machines are recommended.
