Health and safety
Due to their specific formulation, precautions need to be taken when handling and using UV inks. The oligomers and monomers that are the major constituents of UV inks and varnishes are more or less irritant for the skin (Xi symbol on the labels). On the other hand, once dried, UV inks no longer present any handling risk.

The CEPE (European Council of the Paint, Printing Ink and Artists’ Colours Industry) has published a guide for using UV inks and the precautions that need to be taken -
Precautions to take when printing with UV products

• Ultra Violet radiation with wavelengths less than 220 nanometers produces ozone. An over-concentration of ozone can cause a stinging sensation in the eyes and headaches.
The ozone produced must be evacuated.
In all UV drying installations, the ozone is evacuated to the exterior of the workshop by the same ventilators used to cool the lamps. It is therefore vital to check that these ventilators are working correctly.
• UV lamps act as generators of heat. Avoid any contact with the drying system, which can cause serious burns.
• In the same way, avoid any visual contact with the UV radiation, which can cause burns to the eyes.
