Abstract: A radiation-curable ink composition for application to glass, ceramic, or metal by an inkjet printer. The ink composition can be applied to a glass, ceramic, or metal substrate to decorate, protect, etc. the substrate. In some embodiments, the ink composition includes a glass frits component, a chromophore component, and a UV-curable component. The glass frits component facilitates the fusing of the ink component with a glass, ceramic, or metal substrate to which the ink composition is applied. The chromophore component is the primary colorant of the ink composition. The UV-curable component facilitates activation of polymerization upon exposure to ultra-violet (UV) radiation, which causes the ink composition to cure and fix/pin to the underlying substrate. After the ink composition is applied to a substrate and cured by exposure to UV radiation, the substrate is heated to a temperature that causes the ink composition to fuse with the substrate.
