Methods for securing variable indicia on instant (scratch-off) tickets |
| abstract |
A security-enhanced document, such as an instant lottery ticket, includes a substrate. Indicia is provided on the substrate, and a scratch-off-coating (SOC) layer is applied over the indicia to maintain the indicia unreadable until removal of the SOC layer. The indicia is printed onto the substrate as pigmented particles. One or more opacity film layers may be provided over or under the pigmented particle indicia. |
