Four points of UV printer

With the continuous opening of the Chinese economy and full integration with the world, coupled with the rapid development of China's advertising industry, traditional printing equipment such as screen printing and large jet printers are gradually unable to keep up with the trend.

Nowadays, there are more print items, and many of them are to be printed on flatbeds. The advent of UV printers has perfectly filled these gaps. In fact, UV printers contain a lot of tips, let's take a look!

1. UV light

The UV light is not visible to the naked eye, but the UV light will generate a period of electromagnetic radiation. The wavelength of electromagnetic radiation is calculated in nanometers (nm). The larger the value, the wider the range. The wavelengths used on UV equipment are mainly the following. 253.7nm, 303nm, 334nm, 365nm, 366.3nm, among which the line spectrum of 365nm and 366.3nm occupies a great advantage. Ultraviolet (UV) is used in industrial production, and long-wave ultraviolet (UV-A) wavelength is generally used in the world The uv-A region has the best effect at about 365nm, which is also recognized in the industry and unified by the country.

2. UV ink

UV printing is a professional printing technology, which is very different from ordinary printing. UV printing requires a designated ink. This ink is called UV ink. Compared with ordinary ink, UV ink has more characteristics, such as UV inks will not dry without being exposed to ultraviolet light, which means that UV inks will not dry after opening the lid, but ordinary inks will not work. If you do not pay attention to the seal after opening, it will dry.

UV inks are mainly composed of the following components: monomers, pigments, auxiliaries, quasi-polymers, photoinitiators, that is, sensitizers, etc. Compared to ordinary ink UV inks, it can better reflect the value of high-end printed matter, which is also people's Material pursuits brought about by the improvement of life.

3. UV product field

UV is widely used. UV products include glue, paint, ink, etc. Generally speaking, it is cured by ultraviolet radiation. UV products need to cooperate with UV curing machine to complete curing, in order to achieve the finished product effect.

4. The benefits of UV equipment

The benefits that UV printers bring to the company are many. The profitability of the company is inseparable from the cost. The two aspects of manpower and quality also determine whether the company has a profit. The UV equipment is a fully automated device. UV curing through the equipment can help the company. Reducing the waste of human resources, while ensuring quality, plays a certain role in improving the quality of the enterprise, and good quality after-sales is worry-free.

UV curing principle: Add a photoinitiator (or photosensitizer) to a specially formulated resin. After absorbing high-intensity ultraviolet light in ultraviolet (UV) light curing equipment, active radicals or ionic groups are generated, which initiates polymerization and cross-linking. The grafting reaction allows the resin (UV coating, ink, adhesive, etc.) to change from a liquid state to a solid state within a few seconds.
