A method of conferring interactivity on a pre-printed image containing text. The method comprises the steps of: (i) receiving association data indicating an association between an impression identity, absolute positions and a scanned image; (ii) performing Optical Character Recognition on the scanned image to convert text images into computer text; (iii) generating an input description for the scanned image; and (iv) storing a page description comprising the input description and the scanned image. The page description is indexed with the impression identity and, further, the page description is retrievable so as to confer interactivity on the image.
