  • Method for placing indicia on substrates having an enamel band thereon
    Patent number: 5684515
    Abstract: Indicia is affixed to an enamel band on a substrate. An ink suitable for use in known ink jet printers containing inorganic pigments and no frits is applied in a predetermined, easily changeable, pattern to the surface of an enamel band found on a substrate such as plastic or glass. Subsequently the substrate having the enamel band and ink thereon may be heated to a temperature sufficient to cause the frits in the enamel band to adhere to the inorganic pigment in the ink to form permanent opaque indicia on the enamel band in the form of a separate and distinct layer.
