Definitions

  • the invention generally relates to a security sheet or document having one or more enhanced watermarks.
  • Watermarks which are recognizable images or patterns in paper that appear as various shades of lightness/darkness when viewed by transmitted light or by reflected light atop a dark background, have provided protection against counterfeiting security documents for hundreds of years.
  • watermarks and their engaging designs are the most readily recognized security feature available to the general public for the authentication of security documents such as banknotes.
  • the present invention addresses this need by providing enhanced and thus more counterfeit-resistant watermarks in paper and paper-like materials.
  • the present invention provides a security sheet or document having one or more enhanced watermarks, as defined in independent claim 1.
  • the film-like or foil-like security element(s) is a micro-optic security device that projects one or more synthetic images such as the MOTION TM micro-optic security device, which is described in, for example, U.S. Patent No. 7,333,268 .
  • Such devices display colored images on a transparent or tinted background and thus are well suited for use in combination with underlying printed information. It has been observed that these security devices appear to provide the watermark(s) with a multi-tonal appearance. As will be readily appreciated by those skilled in the art, multi-tonal watermarks present an even greater challenge to a counterfeiter.
  • micro-optic devices such as the MOTION TM device may also offer a machine detectable/readable feature in the form of enhanced IR-brightness, especially when measured in transmission.
  • enhanced IR-brightness is intended to mean IR-transmission levels of at least 5% greater than (preferably, more than 10% greater than) the IR-transmission levels of the background paper. IR-transmission levels may be measured by using an optical sensor with a sensitivity at or above 830 nanometers (nm) and by projecting an IR light source with a wavelength greater than 800 nm through the sample.
  • the micro-optic device be made using one or more IR-transparent elements (e . g ., an IR-transparent ink) and contain no IR-absorbing elements ( e . g ., IR-absorbing inks). It is also preferred that no IR-absorbing elements be present in areas close to the device on the front and reverse side of the paper layer(s).
  • the micro-optic device is a security thread ( e . g ., MOTION TM security thread) that contains no IR-absorbing elements.
  • the micro-optic security thread is made using an IR-transparent ink ( e .
  • the inventive security paper is a multi-ply paper that comprises:
  • the second paper layer is windowed, the one or more through windows in the second paper layer being in register with either the upper or face portion or the lower or back portion of the one or more watermarks.
  • the use of two paper layers and optionally one or more overlying or underlying through windows allows for a greater contrast between the one or more watermarks and the background.
  • the one or more overlying or underlying through windows act in a manner similar to that of an electrotype, occupying paperless regions or regions of thinner paper which results in brighter-than-background regions in each paper/watermark region.
  • one or more security elements in the form of one or more color-imparting substances are contained within the first and/or second regions of the one or more watermarks.
  • the one or more color-imparting substances include both dyes and pigments ( e . g ., ultra-fine particle size pigments).
  • the security sheet or document does not include one or more film-like or foil-like security elements.
  • the resulting watermarks have a tonality ( i . e ., color scheme or range of tones) in a color or shade different from that of the bulk region of the material which surrounds the watermark.
  • the inventive watermarks serve to increase the perception and resistance to simulation of existing watermarks.
  • the inventive sheet or document comprises: a fibrous sheet material including one or more watermarks; and means for enhancing the one or more watermarks by rendering them visually enhanced, machine detectable/readable, or both.
  • the watermarks may be formed in the fibrous sheet material using known methods and techniques.
  • the watermarked sheet material may be manufactured on a cylinder mold papermaking machine (using an embossed wire cloth, or by applying a thin piece of metal, generally in the form of an image or letter, to the wire cloth), or on a Fourdrinier papermaking machine (using a dandy roll).
  • the film-like or foil-like security element(s) used in the practice of the present invention is limited only by its film-like or foil-like structure, with contemplated structures having total thicknesses ranging from about 15 to about 100 microns (preferably, from about 15 to about 50 microns).
  • the film-like or foil-like structures may take any shape including, but not limited to, bands, strips, stripes, threads, or patches. They may display or project information that is humanly perceivable either directly or with the aid of a device and/or embody information that is detectable/readable by machine.
  • the structures may be segmented into regions, with the information being displayed or projected or otherwise contained in some or all of these regions being the same or different.
  • the security element(s) is a micro-optic structure.
  • such structures project one or more synthetically magnified optical images, and generally comprise: (a) a light-transmitting polymeric substrate; (b) an arrangement of micro-sized image icons located on or within the polymeric substrate; and (c) an arrangement of microlenses.
  • the icon and microlens arrangements are configured such that when the arrangement of icons is viewed through the arrangement of microlenses, one or more synthetically magnified optical images are projected. These projected images may show a number of different optical effects.
  • Such structures are described in U.S. Patent No. 7,333,268 to Steenblik et al. , U.S. Patent No.
  • the structure being formed from a polymeric substrate prepared using one or more essentially colorless polymers selected from the group including, but not limited to, polyester, polyethylene, polyethylene terephthalate, polypropylene, polyvinyl carbonate, polyvinylidene chloride, and combinations thereof.
  • the micro-optic security device is in the form of a surface-applied elongate strip or thread, or a partially embedded elongate security strip or thread that is present in window regions of a second paper layer ( i . e ., windowed thread).
  • the strip or thread in this embodiment covers all or part of the watermark(s).
  • the micro-optic security device e . g ., the MOTION TM device
  • the micro-optic security device is designed such that when registered with the watermark, synthetic images projected thereby are combined with the watermark design.
  • the synthetic image(s) generated by each patch or thread may coordinate or link in with the watermark design.
  • the synthetic image(s) may also complete the watermark design(s) or locate within the design(s). This may be a one-sided or two-sided feature. In other words, complete information intended to be conveyed to the viewer is not supplied solely by the watermark or synthetic image(s), but requires that both be viewed simultaneously.
  • the MOTION TM patch when viewed at the optimal (perpendicular) viewing angle using visible spectrum-transmitted light, projects a synthetic image in the form of a coat of arms that overlays (in register) the watermark design in the form of a shield.
  • the synthetic image and the watermark design are no longer in register with each other, and one would see the watermark design (shield and numeral 30) within the patch and the synthetic image would transition or switch from the coat of arms to, for example, an array of numerals.
  • An inherent benefit in the exemplary embodiments of the present invention which employ a partially or fully overlying or underlying film-like or foil-like security element such as the MOTION TM micro-optic security device is the increased durability of each watermark. Covering all or part of the watermark(s) with an applied film, foil, band, strip, stripe, thread, or patch serves to physically protect the watermark(s) from damage during circulation and handling, thus increasing its durability.
  • these watermarks may be made larger and that the total area within each watermark occupied by reduced fiber density regions ( i . e ., first regions) may be increased and that these regions may be made even thinner.
  • these reduced fiber density regions may be produced with thicknesses as low as 10 to 15 microns, with total thicknesses ranging from about 10 to about 60 microns.
  • the total area occupied by these reduced fiber density regions within each such watermark ranges from about 5 to about 75 percent (%) of the total area of the watermark, preferably from about 20 to about 60%.
  • the total area occupied by each such watermark within a banknote measuring approximately 10,000 mm 2 may range from about 5 to about 25%, which denotes an increase in size compared to conventional watermarks of about 5%.
  • micro-optic devices such as the MOTION TM device may also offer a machine detectable/readable feature in the form of enhanced IR-brightness, especially when measured in transmission.
  • the micro-optic device be made using one or more IR-transparent elements (e . g ., an IR-transparent ink) and contain no IR-absorbing elements ( e . g ., IR-absorbing inks). It is also preferred that no IR-absorbing elements be present in areas close to the device on the front and reverse side of the paper layer(s).
  • this embodiment of the inventive method does not serve to disrupt fiber distribution around the surface applied security thread, resulting in a higher density fiber distribution with increased substrate density and stiffness which resists security thread deformation, distortion and creasing.
  • the fibrous web 26 is passed through the press, main and secondary dryer and calender sections of the paper-making machine. While in the secondary dryer section of the paper-making machine, the web 26 is exposed to temperatures and/or pressures sufficient to activate the security thread's adhesive coating, causing it to firmly bond the thread in the fibrous sheet material, with the security thread continuously exposed on a front or upper surface of the sheet material partially or fully covering the formed watermark(s), while concealed from view on a back or lower surface of the sheet material.
  • FIG. 6 A cylinder mold process for making a two-ply embodiment of the fibrous sheet material of the present invention is shown in FIG. 6 .
  • this process which employs two cylinder paper machines 36a, 36b, interconnected by pick-up felt 38, two paper webs 40, 42, are formed simultaneously, squeezed together in the area of roller 44, and then fed together to the press, dryer and calender sections of the paper-making machine.
  • the resulting fibrous sheet material has the same physical characteristics as those noted above for sheet materials made using a Fourdrinier process.
  • FIG. 6 shows cylinder paper machines of the wet vat type
  • cylinder paper machines of the dry vat type may also be used to make the fibrous sheet material of the present invention.
  • the inventive fibrous sheet material may be wound up and stored or directly introduced into another machine (e.g. , a printing machine) for further processing.
  • the inventive security paper is a multi-ply paper that comprises:
  • the watermarks are formed by well-known techniques on, for example, a cylinder mold papermaking machine or a Fourdrinier papermaking machine (using a dandy roll).
  • a range of fiber types can be used in making the paper, including synthetic or natural fibers or a mixture of both.
  • fibers or planchettes may be added via random addition to the papermaking furnish, or selectively placed in-line in the position of the see-though security element. In addition, or alternatively, such inclusions could be concentrated in specific cross-direction areas of the paper.
  • These frame-like areas may be treated with the transparentizing material(s) on the papermaking machine, in an off-line web process such as rewinding or respooling, in a dedicated off-line web process prior to sheet cutting, or on individual sheets.
  • the transparentizing material(s) saturates the paper in the applied areas replacing air in the interstices between fibers.
  • This material(s) may be curable or non-curable. Treated areas of the watermarked paper layer allow for the transmission of visible light, thereby framing and thus enhancing the visual perception of watermark(s).
