  • Patent number: 4007462
    Abstract: A method and system for recording information on a document surface to accommodate the automatic processing of documents is provided, which requires neither ink jet nor impact printing. A photosensitive material, such as a dye, is applied as a continuous coat over a field of the document surface. Selected locations within the field thereafter are irradiated with a light beam. The light beam is of an intensity and wavelength to effect a change in the light emitting properties of the photosensitive material at the selected locations. Either alphanumeric or bar encoded information may be recorded thereby on a document surface for subsequent detection by an optical reader.
