UV light in graphic technology: Usage, effects and safety measures

The introduction of ultraviolet (UV) light technologies to the graphic arts in-dustry has revolutionised printing by offering better print quality, faster curing times and the ability to print on a variety of substrates. Despite these advanc-es, UV light and UV-curable materials pose significant health risks to workers. This paper examines the potentially harmful effects of UV light on workers in the graphics technology sector and outlines key safety measures to mitigate these risks. The UV spectrum (100–400 nm) is categorised as UVA, UVB and UVC. While UVA and UVB are partially absorbed by the atmosphere, UVC is almost completely absorbed by the ozone layer. In graphics technology, how-ever, artificial UV light sources can expose workers to harmful radiation. The increasing use of UV light in UV printing and UV curing requires a closer look at occupational hazards. Harmful effects include skin damage (erythema, skin ageing, pigmentation changes, skin cancer) and eye damage (photokeratitis, cataracts, retinal damage). UV-curable inks and coatings also contain pho-toinitiators and chemicals that pose health risks (irritation, allergic reactions and respiratory problems) and require comprehensive safety protocols. Key safety measures include personal protective equipment (PPE) such as protec-tive clothing, goggles and respirators. Technical measures such as UV-block-ing shields, covers and adequate ventilation reduce exposure. Comprehensive training, the use of PPE, safety protocols and regular inspections ensure the safety of employees. By addressing the risk of UV exposure, the industry can protect its employees while continuing to innovate.
