Abrégé
(EN) A method and system for creating game cards incorporates a removable scratch- off coating to hide printed symbols. The card is constructed so that the scratch-off coating is selectively retained by the card, in the form of symbols, when the scratch-off coating is removed. The selective retention of scratch-off coating material to the card is accomplished by incorporating into the card, between the substrate and the scratch-off coating, a clear release coat laser-engraved to form symbols. A laser creates the desired symbols in the release coat. The laser may be manually controlled or computer-controlled using software and drivers for the laser assembly. When the scratch-off coating material is applied to the card during construction, it adheres directly to the substrate in the form of symbols. When a player rubs the scratch-off coating material, it releases from the release coat and remains adhered to the substrate to create the symbols.
