  • Patent number: 10469706
    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.

  • Patent number: 8371616
    Abstract: A false positive testing device (FPTD) that contains a coating based on a one hundred percent solids varnish and a transparent reagent, that uses oxidative free radical polymerization as a drying mechanism, and that can be transferred to various types of porous substrates by conventional lithographic offset printing and/or dry offset printing. The substrates with the FPTD can be verified by using common currency detection protocols, such as testing with ultraviolet lights and/or counterfeit detection iodine based pen/pad stamps.

  • Patent number: 8355179
    Abstract: The present disclosure relates to a printed multi-tonal document with enhanced copy evident distortions security features and a method of printing such document. The document may include a multi-tonal background screen image area including a first set of halftone elements and a multi-tonal foreground hidden warning text and/or graphic screen image area including a second set of halftone elements, wherein the first set of halftone elements may be smaller in size than the second set of halftone elements. The multi-tonal foreground hidden warning text and/or graphic image area, when electronically copied, may appear different from the background of the copy of the document.

  • Patent number: 8355180
    Abstract: 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.

  • Publication number: 20090245613
    Abstract: The present disclosure relates to electronic digital files with document security features to prevent duplication of documents. The method may include selecting a source image previously designed, where a specified tone is used to indicate a background area and another specified tone(s) is/are used to indicate at least one security feature(s) area. The method may also include selecting one or more corresponding tiles and/or one or more corresponding functions for (i) the background area and (ii) the at least one security feature(s) area, generating a converted electronic digital file from the source image with the desired security feature(s) and saving the converted electronic digital file in a format suited for use as a stand-alone graphic image or incorporated into other programs ready for output onto the output device.
