DETAILED DESCRIPTIONДЄ document in accordance with an embodiment of the invention may include a modular, multi-layer architecture definition of a void pantograph that includes a void pantograph background pattern and a void pantograph highlight pattern. In general, pantograph approaches may be used to hide in plain sight a variety of other information that can be read and acted upon. Void pantographs may be used for packaging, labels, documents, or the like.

Some prominent examples of void pantographs are those that are used as backgrounds for checks, which, for example, display вЂњVOIDвЂќ or вЂњCOPYвЂќ on the reproduced image. When reproduced, the hidden element appears on the copied document. The void pantograph may have the word вЂњVOIDвЂќ or вЂњCOPYвЂќ as a hidden element by the use of special screens and/or background designs. A void pantograph may help to make the document hard to duplicate, forge, and/or alter. The control processor provides a printer with data containing a multi-layer architecture document having a document formatted content and a void pantograph highlight pattern.ДЄ void pantograph may be a special pantograph screen printed in the background of a document. The system includes a control processor, a score computation unit and an evaluation unit. The method includes computing a score for a void pantograph highlight pattern layer in relation to a document formatted content layer, incrementing a relative position of the void pantograph highlight pattern layer and the document formatted content layer, repeating the computing and the incrementing steps to obtain a plurality of scores at a plurality of relative positions, evaluating the plurality of scores to determine an optimal alignment, and printing the document using variable-data printing techniques, wherein the printed document has a multi-layer architecture including the document formatted content layer and the void pantograph highlight pattern layer. A method and system for generating a document having a void pantograph highlight pattern is presented.
