First Claim
Patent Images
1. A method of printing an interface onto a surface, the interface including visible text/graphics and coded data, the coded data being indicative of an identity of a region of the surface and of a plurality of locations on the surface, the method comprising the steps of:
- (a) providing a printer comprising;
a data input module for receiving document data from a computer system, the interface being based at least partially on the document data;
a coded data generator for generating the coded data using at least some of the document data;
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;
and (b) printing the visible text/graphics and the coded data onto the surface using the printer,wherein the or 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.

6. The method of claim 5, wherein the ink set has an IR contrast ratio of greater than 7 for at least one absorption wavelength in the range of 800 to 830 nm.
-
7. The method of claim 1, wherein the coded data ink can be sensed by the sensing device when the coded data is overprinted on the text/graphics.
-
8. The method of claim 1, wherein the coded data can be sensed by the sensing device when the visible text/graphics is overprinted on the coded data.
-
9. The method of claim 1, wherein the coded data is substantially invisible to the unaided human eye.
-
10. The method of claim 1, wherein the surface is defined by a substrate.
-
11. The method of claim 1, wherein the printhead is a pagewidth inkjet printhead.
-
12. The method of claim 1, wherein the visible text/graphics and the coded data are printed onto the surface simultaneously.
-
13. A substrate having a surface, wherein the surface includes an interface printed thereon by the method according to claim 1.
