Disclosed methods, computer-readable media, and systems relate to position-coded products and processing data from such products. In one implementation, a computer-readable storage medium stores a program for a computer to perform a method for creating an electronic representation of a position-coded product. The method may access an electronic document file with a set of document pages and map the document pages, copy for copy, within a selected number of copies, to pattern pages according to an ordering of the pattern pages.
