Two limitations of UV printing

The core components of UV printing are UV lamps, which are gas discharge lamps. Gas discharge lamps are divided into arc discharge and glow discharge.

Arc discharge lamp, its working principle is: in the vacuum quartz tube to add quantitative high-purity mercury (mercury), through the two ends of the electrode to provide a voltage difference (pressure drop), resulting in ion discharge, resulting in ultraviolet radiation. Arc discharge lamps generally emit ultraviolet light at higher temperatures, commonly known as thermal ultraviolet light.

Glow discharge lamp, its working principle is: in the vacuum fluorescent tube inner wall uniformly coated with a thin layer of mercury composition, through the two ends of the electrode to provide a voltage difference (pressure drop), resulting in ion discharge, resulting in ultraviolet radiation. Glow discharge lamps generally emit lower temperature UV light, commonly known as cold light UV. Therefore, I have to explain that uv printing surely has an impact on fertility to a certain extent. The most basic protective measure from the self is to minimize the contact with ink and varnish in the process of operation. If you need to contact gloves, or in time Clean; must wear a mask, change regularly; eat almonds and other foods that are beneficial to body toxins. There is a requirement for the factory to provide a well-ventilated workshop; on the day of repair, as much as possible to make the indoor and outdoor air fully circulated; use a suction device; provide employees with masks and gloves; regular medical examinations, physical abnormalities immediately stop work.

Although current UV printing inks have been greatly improved, some limitations of the initial use of UV inks by printers and some of their previous experiences have caused them to have some disgust with the technology. Currently UV inks can meet almost 100% nameplate printing and membrane switch manufacturers. However, the application of UV inks is still far from this level. At present, there are two main factors that hinder the widespread use of UV technology. One is that people are worried that it has certain deficiencies, such as poor lamination performance and creases; the other is achieved in the field of UV ink chemistry. Great achievements are not understood enough.
