Question 1

Are UV inks environmentally friendly?

Accepted Answer

UV inks are environmentally friendly because, unlike solvent-based inks, 100% of the ink is used. The UV radiation from a light source activates photoinitiators to convert the liquid into a solid.

Question 2

Is UV ink durable?

Accepted Answer

UV inks are durable as they can withstand wear, pressure, or damage. Acting more like a thin sheet of liquid plastic, UV inks provide excellent rub, chemical, and light resistance, along with outstanding color consistency and superior gloss.

Question 3

What is the process of UV curing?

Accepted Answer

UV curing uses high-intensity electronic ultraviolet (UV) light creating a polymerization reaction that causes inks, coatings, adhesives, or other photo-reactive substances to transform from liquid to solid.

Question 4

What is a photoinitiator?

Accepted Answer

A photoinitiator is a molecule that reacts when exposed to radiation. Synthetic photoinitiators are key components in photopolymers, including LED-curable and UV-Curable inks.

Question 5

How do photoinitiators work in inkjet inks?

Accepted Answer

A photoinitiator molecule absorbs UV light radiation that reacts with monomers and oligomers. The resulting crosslinking cures the fluid into a solid
