UV Light is all around us every day in the form of ultraviolet radiation from the Sun.

The Sun is a source of the full spectrum of ultraviolet radiation, which is commonly subdivided into UV-A, UV-B, and UV-C.

This spectrum of UV radiation can be harnessed for use in many processes that benefit our everyday lives - from curing printing inks and varnishes, to de-contamination of our drinking water and disinfection of the air we breathe.

UV-C rays are the most harmful and are almost completely absorbed by our atmosphere. UV-B rays are the harmful rays that cause sunburn.

​

UV Curing is a photochemical process in which high-intensity ultraviolet light is used to instantly dry or 'cure' UV inks. The UV curing process is based on a photochemical reaction, using light instead of heat, whereby liquid monomers and oligomers are mixed with a small percentage of photoinitiator and exposed to UV energy which cures the ink instantly.

Monochrome UV-C is the shortest UV wavelength (253.7nm). It is readily absorbed by nucleic acids in the cells of micro-organisms (viruses, bacteria, moulds) and is therefore a powerful tool for disinfection and decontamination of water, air and surfaces.
