Abstract:
1. A method of rendering a pantograph on a printing device including one or more colorants comprising: a) defining a foreground region associated with the pantograph, the foreground region defining a pattern associated with one or more characters; b) defining a background region associated with the pantograph, the background region suitably sized and arranged for encompassing the foreground region; c) selecting a target color for rendering the foreground region and background region of the pantograph, and generating a first color space representation of the target color, the first color space representation associated with the one or more colorants; d) applying a first UCR/GCR strategy to the background region for rendering the target color within the background region using the one or more colorants, and applying a second UCR/GCR strategy to the foreground region for rendering the target color within the foreground region using the one or more colorants, whereby the foreground region is less discernable by a naked eye after the pantograph is rendered with the printing device relative to a reproduction by a copier of the pantograph rendered with the printing device, the copier including a scanner which scans the pantograph in a second color space, distinct from the first color space, whereby the reproduction includes the foreground region discernable by the naked eye; and e) rendering the foreground region and background region on the printing device.
