UV printers use ultraviolet LED lights to dry or cure ink during the printing process. Attached to the print carriage is a UV light source that follows the print head. The LED light spectrum reacts with photo-initiators in the ink to instantly dry it so that it immediately adheres to the substrate.
With instant curing, UV printers can create photorealistic graphics on a variety of materials including items like plastic, glass, and metal.
Some of the major benefits that attract businesses to UV printers are:
Environmental Safety
Unlike solvent inks, true UV inks release little to no volatile organic compounds (VOCs) which makes this printing process eco-friendly.
Faster Production Speeds
Inks cure instantly with UV printing, so there’s no downtime before finishing. The process also requires less labor and enables you to get more done in a shorter period than with other printing techniques.
Lower Costs
There are cost savings with UV printing because there’s often no need to use additional materials in finishing or mounting and additional protection with laminates may not be needed at all. By printing directly to the substrate, you end up using fewer materials, which can save you time and labor.
