Enhanced Security of Scratch-Off Products Using Homogenous Inks or Dyes
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.
1 . A scratch-off product with enhanced security comprising:
a substrate;
indicia printed on a layer of the substrate;
a protect and release layer printed above the indicia;
a scratch-off coating printed above the protect and release layer, wherein
the scratch-off coating includes an upper opacity layer that has the same or a similar chemical composition as the indicia.
2 . The scratch-off product with enhanced security of claim 1 , wherein the substrate includes a lower opacity layer that covers the entirety of the substrate and the indicia has the same or a similar chemical composition as the lower opacity layer.
3 . The scratch-off product with enhanced security of claim 1 , wherein the protect and release layer covers the entirety of the substrate.
4 . The scratch-off product with enhanced security of claim 1 , wherein the upper opacity layer covers the entirety of the substrate.
5 . The scratch-off product with enhanced security of claim 1 , wherein the scratch-off coating further comprises an overprint layer printed above the upper opacity layer that has the same or a similar chemical composition as the indicia.
6 . The scratch-off product with enhanced security of claim 1 , further comprising a display layer that has the same or a similar chemical composition as the indicia.
7 . The scratch-off product with enhanced security of claim 6 , wherein the display layer is printed on the same layer as the overprint layer.
8 . The scratch-off product with enhanced security of claim 6 , wherein the display layer and the indicia are printed on the same layer.
9 . The scratch-off product with enhanced security of claim 6 , wherein the display layer is printed on the substrate.
10 . The scratch-off product with enhanced security of claim 1 , further comprising a layer printed on the backside of the substrate that has the same or a similar chemical composition as the indicia.
11 . The scratch-off product with enhanced security of claim 1 , wherein the indicia is comprised of a graphical image.
12 . A method of printing a scratch-off product with enhanced security, the method comprising:
feeding a substrate into a printing press;
printing indicia on a layer of the substrate;
printing a protect and release layer above the indicia;
printing a scratch-off coating above the protect and release layer, wherein
the scratch-off coating includes an upper opacity layer that has the same or a similar chemical composition as the indicia.
13 . The method of claim 12 , further comprising, printing a lower opacity layer on the substrate and printing the indicia using the same or a similar chemical composition as the lower opacity layer.
14 . The method of claim 12 , further comprising, printing a layer on the backside of the substrate that has the same or a similar chemical composition as the indicia.
15 . The method of claim 12 , further comprising printing the protect and release layer to cover the entirety of the substrate.
16 . The method of claim 12 , further comprising printing the upper opacity layer to cover the entirety of the substrate.
17 . The method of claim 12 , further comprising printing an overprint layer above the upper opacity layer using the same or a similar chemical composition as the indicia.
18 . The method of claim 13 , further comprising printing a display layer above the lower opacity layer using the same or a similar chemical composition as the indicia.
