20110310404 | VOID PANTOGRAPHS AND METHODS FOR GENERATING THE SAME - A void pantograph and a method for generating the same are disclosed herein. The void pantograph includes a foreground portion based on a region of an image that is defined using a predetermined filter, and a background portion based on another region of the image that is defined using the predetermined filter. | 12-22-2011 |
20110310441 | METHOD FOR USING VOID PANTOGRAPHS - A method for using void pantographs involves generating a test sheet including multiple void pantographs, where each of the multiple void pantographs includes a pantograph foreground and a pantograph background. The test sheet is printed, and from the printed test sheet, at least one of the multiple void pantographs having a covert or semi-covert pantograph foreground and background is identified. The printed test sheet is scanned, and from the scanned test sheet, at least one of the multiple void pantographs having an overt pantograph foreground is identified. A workflow is developed for the at least one of the multiple void pantographs having both i) the covert or semi-covert pantograph foreground and background after printing, and ii) the overt pantograph foreground after scanning. | 12-22-2011 |
