Just like that, it's very dry. In just a few milliseconds, when UV ink is exposed to strong ultraviolet rays, it will change from liquid to solid. This reality opens up opportunities for those who use sheet-fed offset printing presses. In the past few years, UV curing has been improved, using LED light sources that generate much less heat than traditional mercury lamps, while using much less energy, and have a longer service life (20,000 hours vs. 3,000 hours). For some sheetfed offset presses, the motivation to switch to UV-LED curing comes from the motivation to enter new markets and use new materials. For others, the attraction is faster turnaround time.

This article will discuss UV-LED technology from the perspective of printing press manufacturers; UV-LED retrofit suppliers whose systems can convert traditional offset presses into new curing technologies; and users of UV-LED sheetfed offset presses, they will discuss Their experience in using UV-LEDs and the benefits they derive from them.
