The method as defined in claim 2 wherein after printing and scanning the method further comprises: identifying a plurality 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 and selecting, for the segmenting step, at least one of the plurality of the multiple void pantographs having a most distinguishable pantograph foreground compared to its corresponding pantograph background after scanning.ħ. The method as defined in claim 4, further comprising identifying with statistical significance a printer used to print the at least one of the multiple void pantographs from the analysis.Ħ. The method as defined in claim 2 wherein analyzing the at least one region of interest includes associating image characteristics of the at least one of the multiple void pantographs with previously stored image characteristics of an other void pantograph previously printed with at least one printer.ĥ. The method as defined in claim 2 wherein analyzing the at least one region of interest includes: performing a pattern recognition process on the at least one region of interest and from the pattern recognition process, identifying with statistical significance a printer used to print the at least one of the multiple void pantographs.Ĥ. The method as defined in claim 1 wherein prior to developing the workflow, the method further comprises: segmenting 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, thereby identifying at least one region of interest for the at least one of the multiple void pantographs and analyzing the at least one region of interest wherein the workflow is based upon the analysis.ģ.
A method for using void pantographs, the method comprising: generating a test sheet including multiple void pantographs, each of the multiple void pantographs including a pantograph foreground and a pantograph background printing the test sheet identifying from the printed test sheet at least one of the multiple void pantographs having a covert or semi-covert pantograph foreground and background scanning the printed test sheet identifying from the scanned test sheet at least one of the multiple void pantographs having an overt pantograph foreground and developing a workflow 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.Ģ.
