UV (Ultra Violet) printing is a form of digital printing that uses ultra-violet lights to dry or cure ink as it is printed. As the printer distributes ink on the surface of a material, a specially designed UV light that is attached to the printing head mechanism follows close behind, “curing” or “drying” the ink instantly.
The use of digital UV printing is at the forefront of the digital printing world. It is the fastest growing sector of digital inkjet printing and more sustainable than conventional printing.
UV printing technology offers the user direct-printing capabilities onto a virtually limitless range of media allowing quick and easy product customisation. The UV ink is printed directly onto the substrate and when the inks are exposed to UV light they turn from a liquid, to a solid instantly.
UV printing technology is the fastest growing trend in the digital printing industry replacing traditional screen and pad printing applications. The main difference between the two is that the UV ink is cured using a photomechanical process rather than solvent evaporation therefore eliminating VOC’s (Volatile Organic Compounds). Printing with UV allows printers to work in a cleaner and safer environment due to the zero emission of solvents into the air. The environment also benefits through the lack of need to use solvents in the clean-up process.
