Definitions

  • the present invention relates generally to the field of lottery tickets, and more particularly to security measures for instant scratch-off lottery tickets.
  • scratch-off lottery games tempt certain unscrupulous individuals to "prescreen" tickets to determine which tickets are winners. For example, such individuals look for ways to covertly determine the play indicia under the scratch-off layer without leaving an indication that the ticket has been tampered with. If a store clerk or other individual can determine a winning ticket in this manner, he can easily remove the ticket from sale to the general public for later "purchase” by an accomplice. Such events seriously degrade the integrity and public perception of the lottery game as a fair game of chance.
  • This patent describes a system and method for electronic verification of tickets.
  • Electronic circuits are printed on the tickets, for example as a component of the scratch-off coating, and any attempt to alter the coating in order to determine the underlying play indicia results in a change in the electronic signature of the ticket.
  • a verification machine is used to apply an excitation signal to the ticket, and a validation circuit is used to determine if the returned signal is a valid signal.
  • U.S. Pat. No. 8,366,153 describes a scratch-off lottery ticket that is provided as a substrate having at least one play area with play indicia provided thereon.
  • a scratch-off layer is disposed over the play indicia and, after purchasing the ticket, a player removes the scratch-off layer to reveal the play indicia, which indicates whether the ticket is a winning ticket.
  • a luminescent material is provided on the ticket. This luminescent material is disposed relative to the scratch-off layer and the play indicia such that any removal of the scratch-off layer to reveal the underlying play indicia is rendered optically apparent upon

  • phosphorescent compound added to a layer underlying the scratch-off material, such as to the generally clear protective coating that is applied over the play indicia.
  • a fluorescent ink layer may be printed under the scratch-off layer, or a luminescent compound may be added to the ink compound used to print the play indicia.
  • a scratch-off lottery ticket wherein luminescent markers or tags are dispersed throughout one or more initial primer layers applied in a printing process to the ticket substrate.
  • an excitation source such as an IR light
  • these markers or tags illuminate and reveal fraudulent attempts to remove or breach the overlying scratch-off layers.
  • the present inventor has determined that the luminescent markers can be added during the printing run of the tickets without adding additional processing steps or time, which is an important consideration in high-speed ticket runs necessary to meet the increasing demand for instant scratch-off iottery tickets.
  • a substrate which is typically a paper stock, is supplied to the printing press line, the substrate having a front face and a back face. Any one of well-known primer materials are printed onto the front face of the substrate.
  • Conventional primer materials are typically supplied in aqueous form with particulates suspended therein. Upon drying, the particulates form a coating or layer that is well-suited for acceptance of subsequently applied printed indicia or ink layers.
  • Game play indicia is printed on the primer layer in a designated game play area. This play indicia determines whether or not the ticket is a winning ticket according to the rules and theme of the Iottery game.
  • One or more scratch-off layers are then applied over the play indicia in the play area.
  • the primer layer further includes a particulate luminescent material homogeneously dispersed throughout. This material is selected such that the luminescent particle size and additive amount is non-disruptive to the primer printing process.

  • One or more primer material layers are printed onto the front face, wherein the primer material includes a particulate luminescent material homogeneously dispersed throughout when dried.
  • the particulate luminescent material has a particle size and additive amount relative to the primer material such that the particulate luminescent material does not add processing or material drying time to the primer material layer as compared to primer material without the particulate luminescent material.

Abstract

La présente invention concerne un billet de loterie à gratter et un procédé de production associé, un matériau d'apprêt étant appliqué comme une couche séchée sur une face avant d'un substrat de billet, des indices de jeu étant imprimés sur la couche d'apprêt dans une zone de jeu désignée, et une couche à gratter étant appliquée sur les indices de jeu. La couche d'apprêt comprend un matériau luminescent particulaire dispersé de manière homogène sur toute sa surface, ledit matériau luminescent particulaire ayant une taille de particules et une quantité ajoutée par rapport à la couche d'apprêt telles que le matériau luminescent particulaire ne requiert pas de traitement ou de temps de séchage de matériau supplémentaires à l'application de la couche d'apprêt. Des tentatives frauduleuses d'enlèvement de la couche à gratter pour révéler les indices de jeu sous-jacents sont rendues optiquement apparentes par la luminescence du matériau luminescent particulaire lors d'une excitation subséquente de la zone de jeu par une source d'excitation.
