  • Card with integrated overprinting
    Patent number: 5569512
    Abstract: Cards and methods of securing hidden symbols on cards are disclosed. The cards, such as instant-win lottery tickets, utilize continuous overprint inks that mask the boundaries between their "secure" and "unsecure" portions to inhibit unscrupulous players from successfully tampering with them. By reformulating the overprint inks to permit a single set to be applied to both portions of a card, more vibrant and aesthetically-pleasing graphics may be displayed as well while utilizing fewer printing stations during the printing process.
