Patent ID: 8891136

Claim:
A method for generating a document, the method comprising: printing a test sheet, photo-imaging the printed test sheet, and comparing the printed test sheet with the photo-imaged test sheet, the test sheet including a plurality of test pantographs, each test pantograph including a pantograph background pattern and a pantograph highlight pattern; selecting a test pantograph having (1) an overt printed pantograph background pattern and a covert printed pantograph highlight pattern, and (2) an overt photo-imaged pantograph background pattern and at least a semi-over photo-image pantograph highlight pattern; computing a score for a void pantograph highlight pattern layer including the pantograph highlight pattern of the selected test pantograph in relation to a document formatted content layer including the pantograph background pattern of the selected test pantograph; 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.
