UV Curable
UV curable inks consist of liquid prepolymers, monomers, and
initiators which upon being exposed to large doses of U.V. Radiation
instantly polymerize the vehicle to a dry, tough thermosetting resin.
They also require less energy, overall, to dry or "cure"
compared to gas or electric driers.
The down side of UV inks is they can cost as much as three times
that of regular inks and must be handled differently than conventional
inks due to safety issues. Additionally, solvents are required for
clean-up which results in some VOC emissions.
Plastisol Inks
Plastisol inks (both solvent and water based) are used in textile
screen printing.
Solvent Inks & Water Inks
Solvent and water based screen printing inks are formulated with
primarily solvent or water. The solvent evaporates and results in VOC
emissions. Water based inks, though they contain significantly less, may
still emit VOC’s from small amounts of solvent and other additives
blended into the ink. The liquid waste material may also be considered
hazardous waste.
