1. A system for calibrating a document processing device from a composite document, comprising: an input device to receive input of a composite document comprising an image human-readable content located in a foreground of the document and positioned relative to machine-readable code marks located in a background that are registered with the human-readable content and are encoded with at least one spatial pointer comprising a location identifier and supplementary information comprising at least one of human-readable characters, physical parameters, predefined information, and reference values for an ideal version of the human-readable content into a document processing device; a decoding module to decode the machine-readable code marks to determine the location identifier and the supplementary information, wherein the location identifier comprises spatial relationships of the relative positions between the foreground and the background for the ideal version of the human-readable content; a comparison module to compare the spatial relationships of the ideal version of the human-readable content with spatial relationships between the foreground and the background of the composite document and to identify distortions based on the comparison; and a calibration module to calibrate the document processing device based on the identified distortions.
