UV printing is a distinctive form of digital printing that involves the use of ultraviolet (UV) light to cure or cure UV ink.. 
The process of UV printing is similar to that of solvent printing. However, the inks used and the drying and curing processes differ. This is in addition to the distinctive nature of the printing technology itself.

UV printing uses specialized UV inks. Instead of heat, high-intensity UV LED lights are used to harden the ink onto the print media. The UV light follows closely behind the ink as it is distributed over the substrate and as a result the ink dries instantly no matter what material (or materials) is used. Because the ink dries almost immediately, it does not evaporate and as such cannot spread onto the material it is printed on. In addition, no VOCs, ozone or toxic fumes are released into the air. For companies that value sustainability in their printing processes, this feature will be of particular interest. In addition to the quick drying capabilities and environmental friendliness of UV printing, this type of UV printing method and related form of ink transfer can also be used with a variety of materials, including paper, plastic, foil, acrylic, foam, etc.

Advantages of UV printing:
Improved turnaround time due to the way the UV printer cures the ink.

Increased Endurance: UV cured ink is much more resistant to damage such as scratches and marks.

Increased Vitality: the colors of UV cured inks are much sharper than the colors that are printed using traditional printing methods.

Instant drying thanks to UV lights. No waiting hours for the ink to dry or harden.

More consistent, higher quality results thanks to UV coating and UV inks.
