UV Curing Energy
Tongchuang (Guangzhou) Co.,Ltd | Updated: Aug 09, 2016

UV light determines the energy of UV ink holdout in light when UV light penetration, deep penetration especially for UV inks. Printing ink layer absorbed energy depends on the UV lamp power irradiation time (associated with the belt speed)

When the UV energy is low, the polymerization of UV light does not provide sufficient energy, curing is not sufficient, even under UV light irradiation and no amount of time could not be completely cured ink layer depths cannot be cross-linked, thus affecting the hardness and adhesion properties.

Excessive UV energy will make the ink surface curing, surface hardness and brittle holdout, less soft. Ink layer under external force, such as cutting, the edge part of the ink layer will split and fall off of the substrate.

Actual curing time (regulation of conveyor belts), UV furnace according to the UV energy meter accuracy testing and debugging access.
