A system for conferring interactivity on a pre-printed image containing text, the image having been scanned and had a position-coding pattern printed thereon, the position-coding pattern identifying a plurality of absolute positions and an impression identity for the image, the system comprising a computer system configured for: (i) receiving association data indicating an association between the impression identity, the plurality of absolute positions and a scanned image; (ii) performing Optical Character Recognition (OCR) on the scanned image to convert text images into computer text; (iii) generating an input description for the scanned image, the input description describing words of computer text and zones of corresponding text images in the scanned image; and (iv) storing a page description comprising the input description and the scanned image, the page description being indexed with the impression identity, wherein the page description is retrievable so as to confer interactivity on the image.
