Q: What are UV inks and why are they better for the environment?
A: The reason UV inks are more environmentally friendly compared to conventional inks lies within the curing or drying process. Conventional inks are petroleum based and once they're applied to a substrate the curing process begins emitting VOCs (volatile organic compounds), into the atmosphere. A VOC is defined as any compound of carbon which participates in atmospheric photochemical reactions, also known as a greenhouse gas. VOC's are known to cause problems with humans as well as other life on the planet.
UV Inks are a non-solvent based ink that contain monomers and oligomers, small carbon-based molecules that have the capacity to switch from a liquid to a solid instantly. To make the switch, these inks contain highly light-sensitive components called photoinitiators, which cure within seconds after being exposed to UV light. Since UV inks do not contain any petroleum solvents, they never emit any VOCs before or after application.
