CA 2091723
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.
La présente invention vise à rehausser la sécurité des cartes de jeu, notamment des billets de loterie instantanée, grâce à l'ajout d'un motif de nature à créer la confusion sous le primaire appliqué sur le substrat de la carte de jeu et à l'ajout d'un autre motif semblable sur la couche à enlever, au-dessus de l'identification du jeu. La réalisation du motif à l'aide d'une encre qui traverse la carte de jeu à l'application de divers produits solvants permet de rehausser encore davantage la sécurité des cartes de jeu.
