Abstract (en)
[origin: EP0568814A2] Security of game cards such as instant lottery tickets can be improved by locating a confusion pattern (32) below a primer layer (14) on a game cards substrate (12) and by locating another confusion pattern (34) on a release coat (24) above a game card play indica (20). 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.
