The present invention provides an imaging device and method for developing, duplicating and printing graphic media. The imaging device of the present invention is utilized in devices such as copiers, printers, game cards and the like and, comprises a substrate bearing an infrared image producing layer, a thermal image forming layer and a light source. A brief but intense flash of visible light from the light source causes latent heat properties of the infrared layer to generate heat and convert visible light into far infrared light. This far infrared light develops or marks portions of the thermal layer which are adjacent the infrared layer.

Why it's free to use
- Filed October 8, 1991 and granted December 30, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 8, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 8, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
