The method of claim 2 wherein the generating a pantograph background comprises combining two different dot patterns selected from the multiple combinations of dot size and dot placement on an X-Y grid.Ĩ. The method of claim 2 wherein the generating a pantograph foreground comprises combining two different dot patterns selected from the multiple combinations of dot size and dot placement on an X-Y grid.ħ. The method of claim 4 wherein the generating a pantograph foreground comprises combining two different dot patterns selected from the multiple combinations of dot size and dot placement on an X-Y grid.Ħ. The method of claim 1 wherein the generating a pantograph background comprises combining two different dot patterns selected from the multiple combinations of dot size and dot placement on an X-Y grid.ĥ. The method of claim 1 wherein the generating a pantograph foreground comprises combining two different dot patterns selected from the multiple combinations of dot size and dot placements on an X-Y grid.Ĥ. The method of claim 1 further comprising: printing the plurality of different void pantographs assessing visual blending of the foreground and background in the plurality of printed pantograph patterns scanning the printed pantograph patterns using a selected copy machine and assessing the degree that the foreground pantograph pattern stands out in the scanned copy.ģ.
A method of generating a number of different void pantographs, the method comprising: (1) generating a dot pattern for a pantograph foreground by selecting from multiple combinations of dot size and dot placement on an X-Y grid (2) generating a dot pattern for a pantograph background by selecting from multiple combinations of dot size and dot placement on an X-Y grid (3) varying either the pantograph foreground or background pattern by changing dot placement and/or dot size while maintaining the other pantograph pattern static (4) combining the foreground and background pattern to generate a void pantograph and repeating steps (1) to (4) a plurality of times to generate a plurality of different void pantographs.Ģ.
