Abstract (en)
[origin: WO2011117687A1] A method and associated substrate provide for deterring and detecting fraudulent removal of a scratch-off coating (SOC) from a substrate that is formed with at least one scratch-off area and a background area surrounding the scratch- off area. A scratch-off coating is applied to the scratch-off area. A visually distinguishable design is applied over the scratch-off coating and onto the background area. Attempts to lift and replace/reapply the SOC results in misregistered {i.e., misaligned) portions of the design, thereby providing a visual indication of attempts to remove and reapply or tamper with the scratch-off coating.
