Abstract
Thermal printing provides an advantageous route to producing aircraft placards able to withstand the rigorous conditions existing on aircraft exteriors. A graphic is directly printed onto a substrate such as polyester, vinyl or polycarbonate. The placard is protected by a protective layer of a UV curable ink which contains acrylates and silicone. An optional promoter containing a diisocyante can be added to the protective layer. Ultraviolet radiation is used to cure the protective layer. The resulting thermally printed placard performs equally as well as silk screen printed placards while offering economic and environmental advantages.
