Abstract
A printer comprises: a feed mechanism and a printhead assembly. The printhead assembly comprises: a printhead for printing a position-coding pattern onto a surface and a scanhead for scanning a pre-printed graphic image. The printer further comprises an ink supply and a processor configured for generating association data. The association data indicates an association between a scanned graphic image, an impression identity and a plurality of positions.
Claims18
A printer comprising:
- a feed mechanism for feeding a substrate past a printhead assembly, said substrate having a surface bearing a pre-printed graphic image;
- a printhead assembly comprising:
- a printhead for printing a position-coding pattern onto said surface, said position-coding pattern identifying an impression identity and a plurality of positions;
- and
- a scanhead for scanning the pre-printed graphic image;
- an ink supply containing an ink for printing the position-coding pattern;
- and
- a processor configured for generating association data, said association data indicating an association between a scanned graphic image, the impression identity and the plurality of positions,
- wherein said impression identity is initially unassociated with said pre-printed graphic image.

A system for conferring interactivity on a pre-printed graphic image, said system comprising:
- (A) a printer comprising:
- a feed mechanism for feeding a substrate past a printhead assembly, said substrate having a surface bearing a pre-printed graphic image;
- a printhead assembly comprising:
- a printhead for printing a position-coding pattern onto said surface, said position-coding pattern identifying an impression identity and a plurality of positions;
- a scanhead for scanning the pre-printed graphic image;
- an ink supply containing an ink for printing the position-coding pattern;
- a processor configured for generating association data, said association data indicating an association between a scanned graphic image, the impression identity and the plurality of positions;
- and
- communication means for communicating the association data to a computer system;
- and
- (B) the computer system configured for:
- receiving the association data;
- and
- storing a page description for said scanned graphic image, said page description being indexed with said impression identity
- wherein said page description is retrievable so as to confer interactivity on the graphic image, and
- wherein said impression identity is initially unassociated with said pre-printed graphic image.
