Abstract

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.

Claims

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.

2. The method of claim 1, wherein the or each visible text/graphics ink has a absorption of less than 10% at all wavelengths in the range of 800 to 900 nm.

3. The method of claim 1, wherein the coded data ink is an IR ink having a absorption maximum in the range of 780 to 900 nm.

4. The method of claim 3, wherein the ink set includes at least one colored ink selected from the group consisting of cyan, magenta, yellow, black, red, green, and blue.

5. The method of claim 4, wherein the ink set has an IR contrast ratio of greater than 5 for at least one absorption wavelength in the range of 780 to 850 nm, wherein the IR contrast ratio at a given absorption wavelengths is defined as:

$\frac{\%<br><br><br><br>\mathrm{Absorption}<br><br><br><br>\mathrm{of}<br><br><br><br>\mathrm{IR}<br><br><br><br>\mathrm{Ink}}{\%<br><br><br><br>\mathrm{Absorption}<br><br><br><br>\mathrm{of}<br><br><br><br>\mathrm{Cyan}<br><br><br><br>\mathrm{Ink}}.$

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.
