Why are UV laser printers more expensive than fiber optic and CO2 printers?

At present, there are three types of laser printers on the market: UV laser printers, CO2 laser printers, and fiber laser printers. Among them, fiber laser printers and CO2 laser printers are cheap, have long service life, are easy to maintain and operate, and have low environmental requirements. In comparison, UV laser printers have a shorter lifespan and higher prices. Why is this? Today I will tell you about the reasons for the high price of UV laser printers.

Overview of UV Laser Inkjet Printer

1. Higher technical difficulty

The wavelength of the UV laser printer is 355nm, and the wavelength of the fiber laser printer is 1064nm. The wavelength of the ultraviolet laser is the wavelength after frequency doubling on the basis of the wavelength of 1064nm through technology, and the technical difficulty is higher, which causes the price of the ultraviolet laser to be several times that of the fiber laser.

2. Optical accessories are not common

Compared with the optical accessories of fiber laser printer and CO2 laser printer, the galvanometer, lens and other optical accessories of UV laser printer have different materials and thickness of coating, so they are not universal. The optical accessories of UV laser printers are also more expensive due to their special materials and processes.

3. High requirements for accessories

The UV laser printer has cooling equipment to ensure the stable operation of the equipment. There are two types of cooling equipment: water cooling and air cooling. Now, water cooling is the main one on the market. Because there are certain requirements for temperature, excessive temperature will affect the normal operation of the equipment, so the requirements for accessories are higher, and the price of the overall equipment is higher.

At this point, everyone should know the reason for the high price of UV laser printers. So why is it so expensive and so popular? Here we have to talk about its advantages.

1. The printing effect is more precise

Compared with fiber laser printers and CO2 laser printers, UV laser printers have a shorter wavelength. These short wavelengths allow the UV laser to focus more precisely and maintain excellent positioning accuracy, resulting in finer prints for the demanding coding industry.

Second, "cold processing"

High-energy (ultraviolet) photons break the chemical bonds of the material, so that the material is destroyed by a thermal process. The printed characters, patterns, two-dimensional codes, etc. are clear, beautiful, and not easy to be smeared and tampered with. This "cold working" method basically does not produce "thermal damage", so it does not cause heating or thermal deformation to the inner layer and nearby areas of the material to be processed, making the industry more widely used.

Because the damage to the surface of the material by "cold working" is minimized, the UV laser printer is very suitable for printing on some thinner plastic materials.

Printing effect on the packaging bag

The non-toxic and non-polluting characteristics of UV laser inkjet printers make it easy to handle higher-demanding coding tasks, such as the needs of printing inside food bottle caps. Because the inside of the bottle cap is in direct contact with the food in the bottle, it must be completely non-toxic and harmless.

The characteristics of "cold processing", short wavelength, high degree of refinement, non-toxic and non-polluting UV laser printer make it widely used in the food industry.

3. Environmental protection, no consumables

The UV laser printer achieves the purpose of marking by non-thermal damage to the surface of the material by the laser beam, so there will be no consumables in daily use. This working mechanism also makes the laser printer more environmentally friendly and safer.

Of course, the advantages of UV laser inkjet printers include flexible installation, simple and easy operation, modular structure for easy maintenance and maintenance, and a wide range of applications. It is these advantages that make it stand out among many inkjet printers and are recognized by the majority of enterprises.
