A method of printing digital data onto or with a photograph using infra-red ink and using an ink jet printing process is disclosed. The data can store the details of the image in an encoded fault tolerant form enabling the copying or recovery of the photograph notwithstanding damage thereto.
Claims7
A method of printing digital data on a photograph including the steps of:
- a) receiving image data corresponding to an image;
- b) converting said image data into an encoded fault tolerant digital form;
- c) printing out said fault tolerant digital form of said image data using an ink jet printing process with an invisible ink on a surface of a print media while simultaneously printing out said image data as a photographic image representing said image data in a visual, human readable form on the same surface.
An apparatus for printing in infra-red ink encoded fault tolerant digital data on a photograph, said apparatus including:
- a) a camera system for imaging an image and for outputting said image in a digital format;
- b) means for processing said digital format of said image into a fault tolerant encoded digital form;
- c) means for printing said image and said fault tolerant encoded digital form using an ink jet printing process, said fault tolerant encoded digital form being printed using an infra-red ink.
