Abstract

See full text

A method of generating a large number of different void pantographs quickly and easily enables selecting a void pantograph that works best with a particular copy machine make and model. The background patterns are generated by varying the size of the dots and placement of the dots on an X-Y grid. The foreground pattern is generated by varying the size of the dots and placement of the dots on an X-Y grid. The foreground and background patterns may be generated by combining two separate patterns. A foreground pattern is combined with multiple background patterns to produce the different void pantographs. A full page of void pantographs having a similar density is tested on a copy machine to determine which one works the best.
