LED UV uses an innovative drying method called UV curing which is proving very
successful. Instead of heat, ultraviolet light dries the ink and it only takes a split
second. The process improves the turnaround time and helps the ink retain its
depth of colour and quality. LED UV uses around 20% less ink than conventional
printing presses as the quick drying time reduces absorption and dispersion of
the ink into the stock.
The method dramatically improves physical properties, meaning your printed media will be shown off with an improved high definition finish.
To go into slightly more depth, the UV light used comes from a particular portion of the light spectrum, usually considered to be in the wavelength range from 200nm (nanometers) to 400nm. In this range, the light has many important uses ranging from water purification, semiconductor lithography as well as adhesive curing - which is how it links with LED UV printing as the light instantly hardens the inks, coatings and adhesives.
