A radiograph identification and filing apparatus for photographically imprinting film and filing the radiographic film, comprising an adhesive-backed label, a release liner to which the label is releasably adhered, and a jacket for storing the radiographic film. The label, the adhesive backing for the label, and the release liner all transmit white light. The label is divided into a plurality of information fields, comprising a machine-readable field, an imprint field, and a background field, which include print information material opaque to white light. The information material in the machine-readable field comprises a pair of spaced-apart parallel positive images of a bar code representing a number for identifying the radiograph. The information material in the imprint field comprises a negative image of the bar code. The information material in the background field comprises information about the radiograph. The jacket includes a pocket for receiving the radiographic film and exterior surfaces for receiving the label. The method comprises providing a darkroom imprinter, a label having an imprint field having substantially the same dimensions as the light window of the imprinter, and a jacket for storing the radiographic film; exposing the radiographic film to Xrays while shielding an information portion of the film from the X-rays, the information portion corresponding in size to the imprint field of the label; interposing the imprint field of the label between the information portion of the film and the light window of the imprinter; exposing the information portion of the film using the imprinter; removing the label from the imprinter; and adhering the label to at least one of the exterior surfaces of the jacket.
