Abstract

Abstract A piece of printed material has preprinted, hidden data and includes a structure which prevents premature or unauthorized revealing of the hidden lottery or gaming data. For example, an instant scratch-off lottery ticket according to the invention includes a substrate, an ink layer disposed on the substrate, the ink layer including hidden lottery data. An ink-receptive layer is provided between the ink layer and the substrate and includes a first security mechanism for preventing unauthorized detection of the hidden data. A second security mechanism is disposed between the ink-receptive layer and the substrate which further prevents unauthorized detection of the lottery data.
