  • Patent number: 8394462
    Abstract: Described herein are methods for applying multiple layers of a composition to an article. Also presented are articles produced by the methods described herein. The methods include applying a first composition to the outer surface of a game card to produce a first layer, applying a second composition to the outer surface of the first layer to produce a second layer, applying an ink to the outer surface of the first layer, or the outer surface of the second layer, or both, so as to form an image, and applying a third composition to the outer surface of the second layer to produce a third layer.

  • Patent number: 5997044
    Abstract: Information can be retrieved from documents such as game cards and document security can be improved by printing electronic circuits or circuit elements on the ticket. Conductive or semiconductive ink can be printed on the document by using gravure, relief, planographic, letter press or flexographic methods to form the circuit elements. In one lottery ticket embodiment the circuit elements are printed over play indica and under a scratch-off coating so that they are removed when the ticket is played. An electronic verification machine can then be used to determine which portions of the scratch-off coatings covering the play indicia have been removed. A second group of circuit elements can also be printed under the play indicia which improves security by blocking light that may be shined through the ticket and by being tested, along with the first group of circuit elements, for integrity by the electronic verification machine.

  • Patent number: 5667250
    Abstract: Security of game cards such as instant lottery tickets can be improved by locating a confusion pattern below a primer layer on the game cards substrate and by locating another confusion pattern on a release coat above the game card play indica. Game card security can be further enhanced by using confusion pattern ink that bleeds through the game card in response to the application of various solvents.

  • Patent number: 5641167
    Abstract: The playability of an instant bingo game card or similar type game cards can be enhanced by providing for improved marking of numbers on a player card portion of the bingo card. In one approach, a space is provided along side each number in which a mark is printed and a scratch-off coating is applied over the mark. In a second approach, a microencapsulated pressure sensitive dye is applied over each number and by simply rubbing a particular number can be marked.

In one embodiment the circuit elements are printed over play indica and under a scratch-off coating so that they are removed when the ticket is played. An electronic verification machine can then be used to determine which portions of the scratch-off coatings coveting the play indicia have been removed. A second group of circuit elements can also be printed under the play indicia which improves security by blocking light that may be shined through the ticket and by being tested, along with the first group of circuit elements, for integrity by the electronic verification machine.
