Definitions

  • the present invention relates to tamper resistant documents and, more particularly, to security documents having designated weakened areas for receiving an image thereon.
  • Security documents Documents which represent money or other value and have an added feature designed to prevent fraudulent use are known in the art as "security documents.” Such documents are sometimes also referred to as “tamper resistant documents.” Security documents include checks, money orders, auto titles, boat titles, birth certificates, death certificates, and like documents of value.
  • a device was used to simultaneously produce a distinctively inked and embossed image of a predetermined amount to be paid on a preselected area of a security document.
  • the device included type having parallel serrations thereon which mated with a sawtooth platen. When the type and platen engaged with one another they acted to severely emboss the paper therebetween and further served to extract ink from an intervening ribbon to produce the inked and embossed image. This method was time consuming and, hence, was not adaptable to the speed of computer driven office machinery.
  • a security document is produced having a designated weakened area which is capable of subsequently receiving an image in an automated printing device such as a dot matrix, a daisy wheel or a chain impact printer, or a laser, an inkjet or a thermal transfer non-impact printer. Thereafter, any attempt to remove or alter the image applied to the weakened area of the document will further weaken the area causing premature failure, thereby providing a visible indication of attempted alteration of the document.
  • an automated printing device such as a dot matrix, a daisy wheel or a chain impact printer, or a laser, an inkjet or a thermal transfer non-impact printer.
  • a security document comprises a substrate of material having a given thickness and including a weakened area for subsequently receiving an image thereon.
  • the weakened area is susceptible to failure upon attempted removal of the image subsequently received thereon.
  • the weakened area on the substrate may comprise a plurality of lines of weakening.
  • the lines of weakening may be formed in a parallel pattern, a diamond-shaped pattern, or any other similar type pattern.
  • a portion of the lines of weakening may comprise cut lines which extend substantially through the entire thickness of the substrate.
  • the lines of weakening may also comprise score lines which extend only partially through the thickness of the substrate.
  • the lines of weakening may additionally comprise a combination of both cut lines and score lines. It is further contemplated that the lines of weakening may comprise a plurality of embossed lines of weakening.
  • the weakened area may alternatively comprise an area of reduced thickness on the substrate formed for example by calendering, grinding or abrading the surface fibers at that area.
  • the area of reduced thickness may additionally include cut lines, score lines and/or embossed patterns formed therein.
  • a pressure-sensitive, color-forming layer may be placed on the weakened area.
  • the color-forming layer may include a colorless color former capable of forming a color, and a color developer capable of developing the colored form of the color former on the application of pressure on the pressure-sensitive, color-forming layer. Any attempt to alter a subsequently received image by the application of pressure will result in a smudge on the weakened area which will be immediately visible.
  • the color-forming layer may comprise frangible microcapsules containing solvent only, dispersed throughout the layer together with minute particles of a colored dye, also dispersed within the layer. Any attempt at alteration will release solvent from the microcapsules, dissolving dye particles and causing penetration and spread of a visible colored solution within and on the document, thereby providing a visible indication of attempted alteration of the document.
  • the security document may comprise a check, money order, auto title, boat title, birth certificate, death certificate, or like document of value.
  • a method for forming a security document.
  • the method comprises the steps of providing a substrate of material having a given thickness, and forming an area of weakness on the substrate for subsequently receiving an image thereon.
  • the area for receiving the image thereon may be preprinted with a uniform solid ink color or have other indicia preprinted thereon.
  • the area of weakness on the substrate is susceptible to failure upon attempted removal of the image subsequently received thereon, thereby providing an indication of attempted alteration of the document.
  • the step of forming an area of weakness may comprise the step of creating a plurality of lines of weakening in an area on the substrate.
  • the lines of weakening may be formed by cutting lines into the substrate which extend substantially through the entire thickness of the substrate.
  • the lines of weakening may also be formed by creating score lines which extend only partially through the thickness of the substrate.
  • the lines of weakening may further be formed by creating a combination of score lines and cut lines in the substrate. It is additionally contemplated that the lines of weakening may be formed by creating a pattern of embossments in the substrate.
  • the step of forming an area of weakness may alternatively comprise the step of reducing the thickness of the substrate at an area on the substrate by calendering, grinding or abrading the surface fibers at that area.
  • the area of reduced thickness may additionally include cut lines, score lines and/or embossed patterns formed therein.
  • a pressure-sensitive, color-forming layer such as described above with respect to the first aspect of the present invention, may be placed over the weakened area.
  • a method for producing a plurality of security documents.
  • the method comprises the steps of: providing a continuous strip of paper having a given thickness; perforating the continuous strip at spaced apart locations thereon to define two or more successive security documents; forming an area of weakness on each of the documents for subsequently receiving an inked image thereon; and, thereafter, applying an inked image on at least one of the documents over its area of weakness.
  • the step of forming an area of weakness on each of the documents may comprise the step of creating a plurality of lines of weakening in an area on each of the documents.
  • Fig. 1 generally illustrates a portion of a security document 10 (also referred to herein as a tamper resistant document), for example a check, a money order, an auto title, a boat title, a birth certificate, a death certificate, or like document of value, which comprises a sheet of paper 12 of a given thickness that bears the usual printed matter on its front surface or face.
  • the security document 10 includes an area for receiving an image 14, such as an amount to be paid.
  • the area for receiving the image 14 comprises a weakened area 16, i.e., the area 16 is purposely weakened prior to receiving the image 14 of the amount to be paid, to thwart unauthorized alteration of the document 10.
  • the area 16 Prior to being weakened, the area 16 may have a uniform solid ink color or have other indicia preprinted thereon. As will be discussed in further detail below, if alteration of the image 14 produced on the area of weakness 16 is attempted, the area 16 will prematurely fail, thereby providing a clear indication that an attempt has been made to alter the document 10.
  • the area of weakness 16 may comprise a plurality of lines of weakening 18 positioned adjacent to one another with paper strips 19 interposed therebetween, as shown in Fig. 1.
  • the lines of weakening 18 may comprise scorelines 20, as illustrated in Fig. 2a, which are cut or otherwise formed in the paper 12 and extend only partially through the thickness of the paper 12.
  • the scorelines 20 may also extend from the upper surface 12a of the sheet of paper 12, as shown in Fig. 2a. While not explicitly shown in the drawings, the scorelines 20 may alternatively extend from the lower surface 12b of the sheet of paper 12, or may extend from both the upper and lower surfaces 12a and 12b of the paper 12.
  • the lines of weakening 18 may also comprises cut lines 22, as shown in Fig. 2b, which extend substantially through the entire thickness of the sheet of paper 12.
  • the lines of weakening 18 may additionally comprise a combination of both score lines 20 and cut lines 22, as shown in Fig. 2c. It is additionally contemplated that the lines of weakening 18 may comprise a plurality of embossed or crushed lines 23, shown in Fig. 2d, or perforated lines (not shown).
  • the lines of weakening 18 may be formed in various alternative patterns in addition to the vertical pattern 21, shown in Fig. 1.
  • Fig. 3a shows the lines of weakening 18 formed parallel to one another and at an angle so as to form a slant pattern 18a.
  • Fig. 3b the lines of weakening 18 are formed parallel to one another in a horizontal pattern 18b
  • Fig. 3c the lines of weakening 18 are formed in a curved pattern 18c.
  • the lines of weakening 18 are formed in a diamond-shaped pattern 18d
  • Fig. 3e the lines 18 are formed in a checkered or square-shaped pattern 18e. It should be apparent that other patterns not explicitly shown or discussed herein may also be employed.
  • the lines of weakening 18 shown in Figs. 1, 2a-2d, and 3a-3e may be formed in the sheet of paper 12 by employing, for example, conventional cutting, scoring or embossing tools, or by employing low profile dies.
  • Well-known knurling tools may likewise be employed to form the diamond-shaped pattern 18d, shown in Fig. 3d, or the checkered pattern 18e, shown in Fig. 3e. It should be apparent that any other well-known process for forming closely spaced cut lines, score lines, and/or embossed patterns may be employed to form the lines of weakening 18.
  • the area of weakness 16 may be formed in the sheet of paper 12 by reducing the thickness of the paper 12 in that area 16, as shown in Fig. 4. This may be accomplished by grinding or abrading the surface fibers in that area 16.
  • score lines 20 and/or cut lines 22 may also be formed in the area 16, as shown in Fig. 4.
  • the area of weakness 16 may comprise a pattern of embossments, such as a plurality of circular embossed regions 24a, shown in Fig. 5a, or a plurality of diamond-shaped embossed regions 24b, shown in Fig. 5b.
  • a pattern of embossments such as a plurality of circular embossed regions 24a, shown in Fig. 5a, or a plurality of diamond-shaped embossed regions 24b, shown in Fig. 5b.
  • Other embossed patterns not explicitly shown or discussed herein may also be employed.
  • a plurality of successive security documents 10, which are detachably connected in sequence, are produced on a continuous sheet of paper 25, as shown in Fig. 6.
  • Each document 10 includes an area of weakness 16 for subsequently receiving an image created thereon.
  • a computer controlled impact printer 40 such as shown in Fig. 6, which includes a printer head 42 and a standard printing ribbon 44, may be employed to form the desired printed numerals and characters on each of the documents 10.
  • the printer 40 and the feed of the security documents 10 can be controlled automatically by the computer. After the documents 10 are printed, they can then be separated from one another via perforation lines 26. While Fig.
  • FIG. 6 schematically illustrates use of an impact printer for creating an inked image on each of the areas of weakness 16 of the documents 10, it should be apparent that other conventional printers, such as non-impact laser printers could likewise be used to create a toned image on each of the areas 16. It should also be apparent that a plurality of separate security documents 10, each including an area of weakness 16 for subsequently receiving an image thereon, may be individually fed to a computer controlled printer (not shown) for forming the desired printed numerals and characters thereon.
  • any attempt to alter the applied image on the area of weakness 16 of the security document 10, such as by use of an eraser or an ink eradicator, will further weaken at least a portion of the paper strips 21 located between the lines of weakening 18, causing premature failure of one or more of the paper strips 21.
  • the damaged paper strips 21 will of course be immediately visible. Consequently, unauthorized alteration of the inked image on the area of weakness 16 will be extremely difficult to accomplish without the alteration being clearly obvious.
  • an area of weakness 16' is formed on a security document 10' for subsequently receiving an inked image thereon.
  • the area 16' Prior to being weakened, the area 16' may be preprinted with a uniform solid ink color or have other indicia preprinted thereon.
  • the area of weakness 16' preferably comprises a plurality lines of weakening 18' which may comprise score lines, cut lines, or embossed lines, formed in the same manner as discussed above with regard to the lines of weakening 18.
  • the area of weakness 16' may also include embossed patterns, similar to those shown in Figs. 5a and 5b, or may comprise an area of reduced thickness.
  • the color-forming layer 30 contains a first chemical substance, a developer, and a second chemical substance which is a color former. Either or both of the first and second chemical substances may be held immobilized in frangible capsules. When the capsules are broken by the application of pressure by a printer, the color former unites with the developer to form a colored material which provides a visible message as determined by the pattern of application of self-contained, or autogenous color-forming material.
  • an impact printer such as shown in Fig. 6, may be used to print the desired numerals and characters in the area 16', and the pressure of the printer on the capsules in the layer 30 causes the encapsulated chemical (assuming only one of the two chemicals is encapsulated) to be released and react with the other chemical to form the printed numerals and characters.
  • Any subsequent attempt at alteration by the application of pressure of any kind, such as by an eraser 32, as shown in Fig. 9, will release more of the encapsulated chemical in layer 30, and this will react with the other chemical and form a smudge 34 around the original printing, and, of course, will be immediately visible.
  • the color forming layer 30 may comprise frangible microcapsules containing solvent only, dispersed throughout the layer together with minute particles of a colored dye, also dispersed within the layer. Any attempt at alteration will release solvent from the microcapsules, dissolving dye particles and causing penetration and spread of a visible colored solution within and on the document 10', thereby providing a visible indication of attempted alteration of the document 10'.
