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.

Claims

1. A game card comprising:

a card substrate having an upper surface and a lower surface;

a play indicia affixed to said upper surface of said card substrate;

a removable elastomeric coating secured to said upper surface of said card substrate over said play indicia; and

a removable confusion pattern interposed between said removable coating and said play indicia wherein said removable confusion pattern is removed when said removable coating is removed.

2. The card of claim 1 wherein a release coat is interposed between said play indicia and said removable coating and wherein said removable confusion pattern is located on said release coat.

3. The card of claim 2 wherein said removable confusion pattern is printed on the upper surface of said release coat.

4. The card of claim 1 wherein said removable confusion pattern is printed with an ink that provides substantially the same appearance as said play indicia when the card is candled.

5. The card of claim 1 wherein said removable confusion pattern has substantially the same print characteristics as said play indicia.

6. The card of claim 1 wherein said removable confusion pattern is printed with an ink which is substantially the same color as the ink used to print said play indicia.

7. The card of claim 1 wherein said removable confusion pattern is printed with an ink that provides substantially the same appearance as said play indicia when the card is candled.

8. The card of claim 1 wherein said removable confusion pattern is a uniform opaque coating.

9. The card of claim 8 wherein said removable confusion pattern is printed with an ink which is substantially the same color as the ink used to print said play indicia.

10. The card of claim 1 wherein said removable confusion patterns is printed in an ink having substantially the same bleed characteristics as said play indicia.

11. The card of claim 1 wherein said removable confusion pattern is printed with an ink including visible materials which form a solution or a dispersion with at least one solvent.

12. The card of claim 11 wherein said play indicia are printed with an ink including visible material which form a solution or a dispersion with at least one solvent.

13. The card of claim 11 wherein said visible materials are the same color as said play indicia.

14. The card of claim 13 wherein said solvents include alcohols, ketones, acetate, esters, alaphtics or amine solutions.

15. The card of claim 11 wherein said confusion pattern ink has substantially the same density as said play indicia.

16. The card of claim 11 wherein said play indicia are printed with varying ink densities.

17. The card of claim 16 wherein said confusion pattern is printed with varying ink densities.

18. The card of claim 16 wherein said ink includes a gray or black grind base.

19. The card of claim 17 wherein said ink is substantially the same color as the ink of the play indicia.

20. The card of claim 1 additionally including a permanent confusion pattern interposed between said play indicia and said upper surface of said card substrate.

21. The card of claim 20 wherein said permanent confusion pattern is printed with an ink including visible materials which form a solution or a dispersion with at least one solvent.

22. The card of claim 21 wherein said visible materials are the same color as said play indicia.

23. The card of claim 22 wherein said removable confusion pattern has substantially the same print characteristics as said play indicia.

24. The card of claim 22 wherein said removable confusion pattern is printed with an ink that provides substantially the same appearance as said play indicia when the card is candled.

25. The card of claim 21 wherein said solvents include alcohols, ketones, acetate, esters, alaphtics or amine solutions.

26. The card of claim 21 wherein said ink includes a gray or black grind base.

27. The card of claim 20 additionally including an opaque primer layer interposed between said permanent confusion pattern and said play indicia.

28. The card of claim 27 wherein said permanent confusion pattern is printed on said upper surface of said card substrate.

29. The card of claim 20 wherein said permanent confusion pattern is printed with an ink having substantially the same density as said play indicia.

30. The card of claim 20 wherein said permanent confusion pattern is a uniform opaque coating.

31. The card of claim 1 wherein said removable confusion pattern is printed with an ink having substantially the same density as said play indicia.

32. The card of claim 31 wherein said play indicia are printed with varying ink densities.

33. The card of claim 32 wherein said confusion pattern is printed with varying ink densities.

34. A game card comprising:

a card substrate having an upper surface and a lower surface;

a play indicia affixed to said upper surface of said card substrate;

a removable coating secured to said upper surface of said card substrate over said play indicia;

a permanent confusion pattern interposed between said play indicia and said upper surface of said card substrate wherein said permanent confusion pattern includes a substantially opaque ink; and

a removable confusion pattern interposed between said play indicia and said removable coating wherein said removable confusion pattern is removed when said removable coating is removed.

35. The card of claim 34 wherein said permanent confusion pattern is printed in an ink having substantially the same bleed characteristics as said play indicia.
