Abstract: In one embodiment, a scratch-off product with enhanced security comprises printing indicia and one or more other layers of the scratch-off product using inks and/or dies having the same or a similar chemical composition as the indicia to protect against attempts to view the hidden indicia without scratching-off the scratch-off coating. Printing the indicia and one or more layers of the scratch-off product using inks having the same or a similar chemical composition substantially reduces and/or eliminates the signal-to-noise ratio of the indicia relative to the other portions of the scratch-off product. In one embodiment, some or all of the layers of the scratch-off product are printed to cover the entirety of the scratch-off product increasing the efficiency of printing scratch-off products.
