The present disclosure relates to a methodology, apparatus and product, of combining a void pantograph security feature with a faux watermark feature creating a resilient void pantograph digitally manipulated in an electronic format and printed through any digital platform from high resolution output devices such as but not limited to film/plate image setters used in standard offset printing, high speed commercial digital ink or toner based presses and printers, and low resolution output devices such as all ink/toner based desktop printers, multifunction printers, in which the amalgamation of the two features authenticate the other feature to produce a document security feature which is self authenticable. Such electronic format can conveniently be issued on-demand onto plain paper using any digital output device driven by an executable software, print driver and/or printer firmware application.
