METHOD AND APPARATUS FOR LABELING X-RAY FILM

An X-ray label includes a substrate that is transparent to X-ray radiation and X-ray absorbing pigment deposited on the substrate in images that provide identification data under visible light and that create corresponding images in an X-ray film emulsion layer when the film is exposed to X-ray radiation. Preferably, the X-ray absorbing pigment is deposited on the substrate using a thermal print process to quickly and consistently transfer X-ray absorbing pigment characters from the ribbon to the X-ray transparent substrate.
