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.
