Abstract:
A method for printing a security document on a substrate is disclosed. Firstly, a first reference image of a reference region of the substrate is generated, the image being indicative of an inherent characteristic of the substrate in the reference region. This is followed by generating encoded data indicative of the inherent characteristic of the substrate. Finally, the encoded data is printed over the reference region of the substrate, thus effecting the print of the security document.
