Printer 19 actually prints the void pantograph test sheet 23.Īfter printing the void pantograph test sheet 23 of 130 cells, for the example, a specific pantograph 31 is identified on the sheet which appears to best hide the “copy” or other void message. Test sheet 23 is generated by the processor 17 and printed by printer 19, for example. Thus, for example, cell 31 would be identified as cell E 9 in test sheet 23. Each cell is identified according to the number of its row 27 and the letter of its column 25. The sheet 23 of 130 different void pantographs is divided into 130 cells. Each cell contains a different void pantograph generated according to the present invention. 2 is a graphical representation 23 of 130 cells. 1, is a system that can be used to generate void pantographs.įIG. 11, copied by the machine of interest.Ī system 15 having a computer 17, a visual display 18, a printer 19 and a scanner/copier 21 communicating with the processor 17, as illustrated in FIG. 12 is a graphical illustration of the void pantograph of FIG. 11 is a graphical representation of a void pantograph selected for a particular machine with an interference pattern andįIG. 10 is a graphical representation of the multiple void pantographs of FIG. 9 is a graphical representation of a sheet of multiple void pantographs, generated for testing įIG. 8A and 8B is a flowchart representing the process by which a pantograph is generated for a specific printer įIG. 7 is a representation of another foreground/background pattern selection įIGS. 6 is a graphical representation of an alternate foreground/background pattern selection įIG. 5 is a graphical representation of one of the foreground/background pattern combinations of FIG. 4 is a graphical representation of the foreground and background patterns and their possible combinations, utilized to generate the void pantographs įIG. 3 is a graphical depiction of various dot configurations and sizes utilized in the present invention įIG. 2 is a graphic illustration of a plurality of pantographs generated by the system of FIG. 1 is a pictorial illustration of a computer printing system utilizing the present invention įIG. The exact nature of this invention, as well as the objects and advantages thereof, will become readily apparent from consideration of the following specification in conjunction with the accompanying drawings in which like reference numerals designate like parts throughout the figures thereof and wherein:įIG. By using different combinations of two different dot patterns to generate the foreground patterns and two different dot patterns to generate the background patterns, the number of different pantographs that can be generated is almost limitless. The background dot patterns are generated by varying the dot size and dot placement on an x-y grid. The foreground dot patterns are generated by varying the dot size, and dot placement in an x-y grid. The present invention provides a method of generating a large, almost limitless, number of different void pantographs, quickly and easily, which can be tested on the printer and copier combination of interest, allowing selection of a VP that works best for that combination.Ī large number of different void pantographs are generated for testing with a particular make and model of machine in order to select the void pantograph that works best with a particular make and model machine. The designing of VPs for the mobile printing world of today, which involves electro photographic printing methods presents an almost insurmountable problem because of the great variety of printing machines. Void pantographs are traditionally designed for use with a specific printing technology, such as flexo, gravure, offset or screen printing, for example. Void pantographs (VPs) have been an important part of the security printing industry for quite a while. The present invention relates to void pantographs and more particularly, pertains to a method of generating a very large number of different void pantographs.
