The basic definition of UV ink

UV gloss ink is a kind of ink without solvent, fast drying speed, good luster, bright color, water resistance, solvent resistance, wear resistance. UV ink has become a more mature ink technology, and its pollutant emissions are almost zero. According to statistics, the annual output of UV ink is about 16,000 tons in Japan, about 18,000 tons in Europe, and about 19,000 tons in North America. It should be noted that the water-based UV ink in UV ink is a new direction in the field of UV ink research. Because the viscosity of the prepolymers in ordinary UV ink is generally large, it is necessary to add active diluent dilution, and the diluent acrylate compounds currently used have different degrees of skin irritation and toxicity, so in the development of low-viscosity prepolymers and low-toxicity diluents at the same time, another development direction is to study water-based UV ink, that is, water and ethanol as diluents. Water-based UV ink has been successfully developed and applied in some printing enterprises.

The basic definition of UV ink

In the printing industry, UV ink is particularly important, it is widely used in packaging, labels, commercial publications and other fields. UV inks have many unique properties that make them the preferred option for many printing companies and brands. In this article, we will delve into the basic definition of UV ink and how it works.

First of all, let's understand the definition of UV ink. UV is short for ultraviolet light, and UV ink is an ink that uses ultraviolet light to cure or dry. UV inks are quick-drying in print jobs, resistant to wear, and capable of producing high-quality prints. Unlike traditional inks, UV inks do not require air drying or hardening by heating. It cures in an instant by ultraviolet irradiation, making printing faster and more productive.

Ultraviolet light on the curing agent triggers a chemical reaction, which then begins to cure the ink to form a hard print pattern. One of the great benefits is that UV inks do not include volatile organic compounds and volatile organic compounds, thus avoiding the deterioration of indoor air quality. Therefore, UV ink can not only produce high quality, but also meet environmental requirements.

UV ink also has many application advantages, has good adhesion, can be smoothly printed on almost any medium, such as paper, metal, plastic, glass, etc., so that it is widely used in various types of printing operations. UV ink in the application process, not only can improve the clarity and details of the printing, but also after printing, the color of the ink is not easy to fade, so as to bring more lasting results for customers. Many brands have a wide range of coverage, which shows the wide use of UV ink.

At the same time, UV ink has higher requirements for printing equipment. Due to the fast curing speed of UV inks, it is necessary to use a special quick-drying system at the ink outlet of the printing equipment. In addition, in order to enable the ink to cure better, special ultraviolet lamps need to be used. This is a special UV irradiation equipment for printing equipment.

In addition, there are a few other details to note. For example, since UV inks are cured by ultraviolet light, direct exposure to sunlight must be avoided to avoid interference from the sun. In addition, when using such inks for many times, attention should be paid to protecting the plate to avoid the use of retarders affecting the printing quality.
