Abstract
A method employing a multi nozzle inkjet printer for recording a photograph and/or additional data in a fault tolerant encoded form on the photograph itself uses infra-red ink permitting recovery of the photograph notwithstanding damage or part destruction of the photograph itself.
Claims5
A method of printing data including encoded image data in a digital format on a photograph including the steps of:
- a) receiving image data corresponding to an image in an electronic digital form from an electronic image sensor;
- b) producing from said digital form of said image data an encoded fault tolerant digital form thereof;
- c) printing out at least, said encoded fault tolerant digital form of said digital image data using a drop on demand ink jet printing process using an infra-red ink on a surface of a print media while simultaneously printing out said image data as a photographic image representing said image in a visual, human readable form on the same surface of said print media.
An apparatus for printing encoded fault tolerant digital data in infra-red on a photograph, said apparatus including:
- a) a camera system for electronically imaging an image and for outputting said image in a digital format;
- b) means for processing said digital format of said output image into a fault tolerant encoded digital form;
- c) means for printing said image in a human readable form and simultaneously printing said fault tolerant encoded digital form using an ink jet printer, said fault tolerant encoded digital form being printed using an infra-red ink over or interlaced with said human readable form of said image.
