Definitions

  • the present invention relates to document security, a method and apparatus executed by a software program on a computer system for digitally producing fixed and unique variable counterfeit-deterring security covert (hidden) and overt (not hidden) features in a printed form using inks of like color corresponding to the substrate color.
  • Examples of such methods and products include currency or banknotes that are printed on special paper having a unique feel or texture, embedding images and/or moire patterns in the original documents that are nearly invisible to the naked eye but which become apparent upon photocopying, printing originals in multiple colors and with fine details that are not easily reproduced, and placing difficult-to-reproduce watermarks or holographic images on the originals.
  • copy-protected media such as paper, generally has a fine printed pattern that makes up a light "colored" background on the paper. This background is typically formed by a pattern of dots, lines, screen structures or the like. Within the background pattern, additional information can be printed that is mostly hidden by the background pattern when viewed by a casual observer.
  • the additional information typically includes a security warning such as the word "VOID” or "COPY".
  • the security warning becomes prominent on the copy such that even a casual observer will notice it.
  • the original document is easily distinguishable from its copied version by virtue of a warning such as "VOID” or "COPY” being prominently displayed on the copied version.
  • a warning such as "VOID” or "COPY” being prominently displayed on the copied version.
  • advancing computer scanning and photocopying technologies have rendered many of the above-described document protection methods substantially less effective and have forced the use of advanced, more expensive and complicated document protection techniques, such as holographs and specialty inks and paper. It is useful to note that with respect to the general field of document protection, it has been the standard practice to incorporate the security features as the final layer or step in the printing operation.
  • the present invention is directed at a document security feature printed onto a print surface of a document, comprising a covert and/or an overt security feature printed with inks/toners having a color that corresponds to the coloration of the receiving substrate.
  • the security feature is substantially less visible and/or invisible to the unaided eye wherein the security feature is revealed to the eye by manipulating said document to reveal said security feature.
  • the present invention is directed at a method to authenticate, track and/or trace a document as an original document, comprising supplying a document to authenticate, track and/or trace and placing on each half-tones line, dash, or dots of any shape on a layer of said document to define a security layer by manipulating and positioning it directly under and/or beside and/or in overlapping relation to any another half-tones line, dash and/or dot of any shape printed on any of the layers above such security layer.
  • the present invention comprises a method to encode containing a visual image as an original document comprising placing one or more half-toned lines, dashes and/or dots on top of one another to provide a security layer, characterized that said one or more half-toned lines, dashes and/or dots positioned on top of one another define a security layer, said security layer thereby encoding said document based upon the number of dots and/or the sequencing and/or positioning of said dots, followed by placement of an image layer
  • the present invention comprises a covert and/or overt security feature printed onto a printable surface wherein said covert and/or overt security feature is computer generated, comprising placing a security feature comprising a line pattern, artwork, line art, picture and/or text onto a substrate layer that is digitally converted into half-tones ranging in density between one to one hundred percent using lines, dashes and any shape dots. The luminosity of said security feature is adjusted by the process of adding or subtracting to the half-tones lines, dashes and/or dots on top
  • Figure 1 is a perspective view of a printed security feature of one embodiment of the present invention
  • Figure 2 is a perspective view of another printed security feature of one embodiment of the present invention
  • Figure 3 is a perspective view of another printed security feature of one embodiment of the present invention.
  • Inks of like color are defined herein as white inks on white substrates (such as standard paper but also include all printable synthetic materials such as but not limiting to plastic, vinyl, PVC, Teslin®, Tyvek®, Polyart®, etc.) and opaque inks on opaque substrate, clear inks on clear substrates, red inks on red substrates and so on and so forth.
  • white inks on white substrates such as standard paper but also include all printable synthetic materials such as but not limiting to plastic, vinyl, PVC, Teslin®, Tyvek®, Polyart®, etc.
  • opaque inks on opaque substrate clear inks on clear substrates
  • red inks on red substrates and so on and so forth are defined herein as white inks on white substrates (such as standard paper but also include all printable synthetic materials such as but not limiting to plastic, vinyl, PVC, Teslin®, Tyvek®, Polyart®, etc.) and opaque inks on opaque substrate, clear inks on clear substrate
  • like color inks can be any Cyan Magenta Yellow and Black inks/toners used for full color process printing and/or spot colors known within the Pantone Matching System® and/or custom colors tailor- made including white, opaque and clear to correspond to the natural coloration of substrate.
  • a white ink on a white substrate is employed to create a white paper that has been impregnated with a first layer security feature thereby producing a white security paper.
  • Figure 1 is a perspective view of a printed security feature of one embodiment of the present invention.
  • a printed security feature 10 is positioned as the first layer, while containing a covert and/or over security feature.
  • the substrate color 12 will therefore preferably correspond to the ink color of the security layer 10, and preferably comprises white ink on white paper. In the context of the above illustration it should therefore be understood that the color of the substrate 12 corresponds to the color of the security layer.
  • Inks herein should also be understood as inks used for all standard dry or wet offset by screen, flexo- and gravure-printing, letterpress or by "Dl" direct image press, inks used for all ink-jet printers, inks used in all ink based digital press such as the "HP Indigo”. Inks are also defined as toners such as toners used for all laser printers/copiers and digital presses for instance the "Nexpress”, “IGen”, “Xeikon” etc.
  • All inks/toners described above may also have other attributes such as optically variable characteristics in "exposed” conditions such as ultra-violet dull for ultra-violet inks/toners, infrared dull for infrared inks/toners, temperature sensitive for thermochromic inks and light sensitive for photochromic or glow-in-the dark inks/toners.
  • the method of the present invention includes printing a security covert and/or overt features with like color inks as the first layer and then overprint this layer with the "normal" visible portion of the document such as preferably printing the security layer with "white” inks onto "white” paper then overprinting this layer with the normal visible image of the document so on and so forth.
  • Figure 2 is a perspective view of another printed security feature of one embodiment of the present invention.
  • the layer of like color inks containing the security features 14 can be printed during the same time as the visible portion 16 of the document or at a separate time using any press, digital press, inkjet and/or laser printers and/or type and hand written by overprinting on a substrate 12 that was previously printed with the security feature using like color inks corresponding to it's substrate.
  • the security feature can be line patterns, artwork, line art, picture and/or text digitally converted into half-tones using lines, dashes and any shape dots and the luminosity (by adding or subtracting to the half-tones lines, dashes and/or dots) may be adjusted according to the image that will be printed on top of this layer.
  • one or more half-toned lines, dashes or dots can all be optionally positioned to print one on top of the other to create a multidimensional security layer underneath the image, as depicted in Figure 3.
  • This multi- dimensional layer as depicted by tiers 18a, 18b and 18c, can further be utilized to encode a document based on the number of dots per tier and the sequencing and positioning of each dot.
  • each half-tones line, dash and/or dot can also optionally be manipulated and positioned directly under and/or beside and/or partly covered in relation to any another half-tones line, dash and/or dot printed on any of the layers above itself for the purpose of encoding the document and thus the final printed document can be tracked, traced and authenticated.
  • each half-tone line, dash and/or dot on the security layer is preferably positioned directly under and/or partly covered in relation to any other half-tone line, dash and/or dot printed using any printing inks including inks with optically variable characteristics (such as ultra violet, inferred inks etc.), on any of the layers above itself, and pending the placement, the "like color” inks used on the security layer, the "like color” inks can be customized to have special chemical and physical properties so that it can also have a interaction with the inks above creating a unique "color signature" on that part of the cover and/or over security features specified to the document.
  • any printing inks including inks with optically variable characteristics (such as ultra violet, inferred inks etc.)
  • An advantage of the present invention is that the method and process will produce variable security features for the digital print platform (such as all digital print output devises as in a digital press such as the HP Indigo, Nexpress, IGen, Xeikon, and/or laser printers/copiers and/or ink-jet printers) and that the method and process may generate a variable feature for each printed document.
  • Another advantage of the present invention is that the method and process will produce self-validating original documents. Authentication is visual by examining the document under normal conditions and/or under "exposed" conditions (such as if the like color ink also has optically variable properties such as ultra violet dull by exposing the document to ultra violet lights).
