Definitions

  • the present disclosure relates in general to methodologies for securing scratch-off lottery tickets and commercial tickets/coupons against assisted and unassisted mechanical lifts and reapplication, as well as a method for protecting against the fraud of recycling losing tickets by the reprinting of a
  • the term 'mechanical lift' refers to a process that uses a flat blade (e.g., X-Acto chisel blade # 7) or other device to peel back a portion of a Scratch-Off-Coating (SOC) to reveal previously hidden indicia. The SOC is then glued back into place such that it is not obvious that the integrity of the coating has been breached.
  • a flat blade e.g., X-Acto chisel blade # 7
  • SOC Scratch-Off-Coating
  • Another form of fraud involves completely removing the SOC, viewing the indicia, and then reprinting a new SOC on the non-winning products (via silk screen or other printing methodology) that is similar in appearance to the original SOC such that an unsuspecting customer would purchase the modified product assuming it is pristine.

  • a visually distinguishable design is applied over the scratch- off coating and onto the background area. Attempts to !ift and replace/reapply the SOC results in misregistered (i.e., misaligned) portions of the design, thereby providing a visual indication of attempts to remove and reapply or tamper with the scratch-off coating.
  • the design is generated and applied such that reapplying the scratch-off coating causes the portions of the design over the scratch-off coating to be misaligned with the portions of the design extending onto the background area.
  • the design may vary broadly within the scope and spirit of the invention, and in a particular embodiment is selected from the group consisting of photographs, fingerprint patterns, water flow patterns, or a series of lines, such as a Benday pattern series of lines.

  • protection of the integrity of the SOC can be provided by alterations to the release material associated with the SOC rather than by an elaborate overprint.
  • Scratch-off tickets typically employ a release coating layer beneath the SOC opaque and decorative layers.
  • the release layer causes any coatings placed over it to easily scratch-off.
  • the physical nature of the scratch-off coating varies from manufacturer to manufacturer (e.g., wax base, UV coating, etc.) and has been documented in numerous other patents as well as many public domain documents and is not essential to the present description.
  • the release layer is specified as a continuous film providing a foundation from which all subsequent layers of ink film will scratch-off, allowing for the one-time reveal that is typical of scratch-off tickets.
  • the problem with this homogeneous continuous release film is that it provides an excellent base for SOC mechanical lifts and/or replacement of the SOC by devious means.
  • a release film with partial coverage causes the SOC to release easily from some areas and not at all from others, thereby making it difficult if not impossible to lift or reprint the SOC even with mechanical assists.
  • the release film 200 is applied as illustrated in FIG. 5 with a pattern of dots (holes) 201 in which no release film is present.
  • the dots 201 are small enough they will not hinder the normal scratching process or obscure the imaged indicia.
  • the presence of a non-continuous release film with holes large enough to prohibit lifting of the SOC will greatly hinder or render impossible mechanical lifting of the SOC due to the dotted areas with no release that would effectively block a sharp X-Acto or razor blade from raising a smooth film.
  • the pattern of dots (holes) 201 would also make it extremely difficult to reapply a new SOC to the scratched off area(s) due to registration problems with the SOC overprint and the multiplicity of dots.
  • the dot pattern is described in for this particular embodiment.
  • FIG. 6 illustrates an irregular or rough SOC film 202, printed on a ticket substrate 103, above the win or lose indicia 252, with opaque and decorative overprints 253 printed on top of the irregular release film 202.
  • the irregular release film surface 202 when initially applied and not completely cured allows for subsequent SOC ink film layers to flow into the irregular surfaces forming a homogeneous and opaque covering 253.
  • the irregularities in the release film may be generated by planned deformities in the Flexographic printing plate (or other type of printing) that applies the release film to the ticket substrate 103.
  • the rough/irregular surface of the release film 202 is not so irregular that it significantly impacts removal of the SOC by normal consumer scratching with a relatively blunt coin or other object.
  • the rough/irregular surface of the release film 202 functions as a series of 'speed bumps' that repeatedly catch the sharp edge of the X-Acto or razor blade typically used in mechanical lifts causing the blades to jerk and not lift a continuous patch.
  • the irregular release film surface 202 does allow removal of the majority of the SOC 253 with blunt coins and other objects (e.g., fingernail), it does allow for microscopic parts of the SOC 253 to remain.
  • the release film coating thickness can be varied, producing a series of plateaus, which halt or disrupt any mechanical lifting attempts.
  • the release film 203 is applied in multiple levels, resulting in a series of planes to which the SOC ink film(s) 253 are applied.
  • the multiple levels of release coating could be achieved by altering the line screen on a single Flexographic printing plate or by the application of multiple printing plates.
  • Krylon clear spray contains keytones, petroleum distillates, toluene, naphthalene, acetone, and ethyl 3-ethoxypropionate. Dyes exist that responds to one of these ingredients. These dyes could be applied as an overcoat to the ticket's scratch area and serve as an obvious indication of attempted "assisted lift" tampering.
  • FIG. 8 provides an exemplary illustration of this embodiment.
  • the lottery ticket 100 has special dyes 255 that are sensitive to one of the key ingredients in the assisted lift medium (e.g., Krylon).

Abstract

L'invention concerne un procédé et un substrat associé permettant d'empêcher et de détecter le retrait frauduleux d'un film à gratter (SOC) d'un substrat constitué d'au moins une zone à gratter et une zone d'arrière-plan entourant la zone à gratter. Un film à gratter est appliqué sur la zone à gratter. Un motif visuellement discernable est appliqué sur le film à gratter et sur la zone d'arrière-plan. Les tentatives de soulèvement et de rempacement/réapplication du SOC créent des parties mal enregistrées (à savoir mal alignées) dans le motif, ce qui permet d'obtenir une indication visuelle indiquant une tentative de retrait et de réapplication du SOC ou une manipulation frauduleuse du SOC.
