  • (a) providing a printer comprising;

    a data input module for receiving document data from a computer system;

    a coded data generator for generating coded data using at least some of the document data, the coded data being indicative of an identity of a region of a surface to be printed on and of a plurality of locations on the surface to be printed on;

    a printhead for printing the interface onto the surface; and

    an ink supply for supplying ink to the printhead, the ink supply comprising an ink set including at least one visible text/graphics ink and a coded data ink, the coded data ink being absorptive of wavelengths in the near-infrared range; and

    (b) printing visible text/graphics and the coded data onto the surface using the printer,wherein each visible text/graphics ink has an absorption of less than 20% at all wavelengths in the range of 800 to 900 nm, where 100% absorption is defined as the maximum absorption of the or each visible text/graphics ink when printed onto the surface.
