    Abstract: A copy-evident document and a method of printing a copy-evident document wherein a void pantograph is created including a first set of halftone elements and a second set of halftone elements different in modulation from the first set of halftone elements. An overlay including a white image with a plurality of halftone hole locations is preferably formed, wherein the halftone elements of the void pantograph are converted to the plurality of halftone hole locations. The overlay is then preferably merged with a background image, such that portions of the background image are visible at the halftone hole locations of the overlay when printed. The merged image is then printed on print media, wherein the portions of the background image that are printed are printed at locations where the holes locations are present in the overlay creating a copy-evident feature.
