14. An apparatus for generating a variable data pantograph comprising: a reception component which receives a variable data string associated with one or more pantograph characters; memory which stores a vocabulary of character representations, each of the character representations in the vocabulary including a foreground region including a font body image shape and a background region suitably sized and arranged for encompassing the foreground region; and a generation component which retrieves a selected one or more of the character representations from the vocabulary which are to form a variable data pantograph corresponding to the received variable data string, associates a respective target color with each of the one or more character representations, associates a first set of color separation control data with the respective target color for rendering the target color in the foreground region, and associates a second set of color separation control data with the respective target color for rendering the target color in the background region for each of the one or more character representations, whereby when the variable data pantograph is rendered as a function of the associated first and second sets of color separation control data of the respective one or more character representations in an original document, the foreground and background regions are similar in tone and the foreground and background regions are substantially less similar in tone in a copy of the original document to render the character visible.
