![]() ![]() It may also result in conjunctivitis, which is inflammation of the mucous membrane lining the inside of the eyelid and the forepart of the eyeball. At high levels chest pains and a cough may occur.Įxposure to UV Light: Exposure to direct UV light may irritate the eyes or burn the skin. Inhalation of ozone: Exposure to ozone gas can lead to eye, nose and throat irritation and at higher levels, headache, or nausea. It can have the potential to cause respiratory sensitization.Ĭontact with wash up solvents: The effects of exposure to wash-up solvents depends on the type of solvent used, and can range from dermatitis to damage to the central nervous system. The mist formed presents a hazard from inhalation and may be irritating to the skin and respiratory tract. Inhalation of ink mist or fly: In some circumstance small ink droplets may become airborne. may cause skin irritation or, in certain people, skin sensitization. How are workers exposed?Ĭontact with UV curable inks, varnishes, etc. Users should be sure they have up to date information on the products and have identified specific hazards before use. Suppliers are required to provide up to date material safety data sheets and to identify key hazards on product labels. UV inks and varnishes as a result of the inclusion of substances to help the formulations or other physical properties of the inks in use may present certain other hazards. In most circumstances the condition is irreversible. For a sensitized person, further contact with the material concerned, even at very low doses, may cause a severe reaction. In certain people exposure to UV inks may result in skin sensitization – an allergic reaction that can manifest itself at any time in some people. Some applications also involve EB technology, such as security printing, where thick film coatings are required.Įxposure to UV radiation, even limited, will cause acute, abnormal redness on normal skin. Applications include carton printing – including food and pharmaceutical packaging, labels, plastic substrates, and metal decorating. Separate varnishing attachments may also be adapted to UV. Many conventional printing machines cam be adapted to use UV inks, varnishes or lacquers. UV technology is important in the production of all types of printing and packaging applications where their fast drying, durable and high gloss finish make them suitable for immediate use. Health, safety and environmental precautions for both UV and EB cured processes are similar. UV cured inks can effectively be considered solvent free, however solvents are still used for press wash-up. Less frequently, an electron beam (EB) is used. Ulraviolet (UV) curable inks, varnishes and lacquers are composed of liquid components which co-polymerize to a plastic solid when exposed to a high intensity UV light source. ![]()
