Experts talk about the development and application of laser die cutting technology (2)

What are the main applications of laser die cutting technology?

Laser die-cutting technology has a wide range of applications.

For one, it can be used for traditional trademarks . Die-cutting of labels and cards. This is also its main application area.

Second, it can be used for anti-counterfeiting. For example, making reliefs. Shaped holes and latent effects. Foreign anti-counterfeiting industry tried to use laser die cutting to produce relief effect around 1997. The stamp industry is trying to use it to stamp perforations, which can not be imitated by mechanical drilling, and can also play a security role, such as tickets for the Asian Cup, the higher the price, we must consider anti-counterfeiting, with Laser drilling for anti-counterfeiting should be very effective. The application of latent images is also a technology that needs to be tapped. If it is used well, it will produce a certain amount of impact on the cutting industry. For example, after a pattern is engraved on paper, the paper on that part is thinner than other parts. If a layer of special material is applied on the surface of the paper, the thickness is the same, but there is a latent image that can play a role. Similar effects to watermarks.

Thirdly, by using the dot-mapping principle, laser ablation produces dense holes that can also form images. This technique has been applied experimentally. A few years ago, foreign countries had already implemented the stamps, but only as proofs.

In this exhibition, the impression is more impressive is MORLOCKGMBH + Co. The mprint system exhibited by KG. According to the company’s technical personnel, the system is mainly used for die cutting of high-end products, such as printing on automotive license plates. After die cutting, stick to the surface of the plate.

Although the application area of ​​laser die cutting is very wide, it is mainly applied to trademarks. Labels, such as stickers. Beer label. Coaster. Logos that represent corporate image and special prints with high anti-counterfeiting requirements.

What is the current use of laser die cutting technology at home and abroad?

As mentioned above, laser die-cutting technology has been applied abroad. For example, mprint has sold 5 or 6 units a year. At present, it has not been heard that the domestic trademark industry has adopted laser die cutting.

What do you think is the reason why laser die-cutting technology has not entered the country?

I have communicated with some people in the industry on this issue. The first thing they considered was the cost issue. Although there was no need to make a die cut, the cost of the laser head was still high. Second, it is speed. When a conventional flexographic printing press is connected to a conventional die-cutting device, the speed can reach 100m/min. If you connect a laser die-cutting device, the average setting is as good as twenty or thirty meters in one minute. In addition, they believe that the domestic delivery time is not yet tight enough to use laser die-cutting, and traditional die-cutting can also cope.

What is your opinion on the future of laser die cutting technology?

For the following two considerations, laser die-cutting is necessary in the country. The first is if you take a diecut. After the hourly depreciation of the laser head made a scientific calculation, the price was close to, or not much different. The second is to consider anti-counterfeiting features, and use anti-counterfeiting to make up for other deficiencies.

In short, with the laser power. With the development of control technology and the emergence of new brands of laser light sources, the cost performance of laser die cutting will gradually increase, and laser die cutting technology will also be applied.

During the interview, I clearly felt that Mr. Jiang was very interested in digital die-cutting technology and was full of confidence in the future development of digital die-cutting technology. Let us wait and see domestic first person to eat crab! (Author: listening to the rain)
