Abstract:
A scratch-off document may include a substrate bearing a toner image and a scratch-off layer covering the printed content. The scratch-off layer may include a mass of a first solid ink and a mass of a second solid ink printed over the first solid ink in a distraction pattern. The toner image is formed of a toner that adheres to the substrate, while the scratch-off layer is made of a wax-based or other solid ink that may be removed from the substrate by scratching without removing the toner image. The distraction pattern includes varying pile heights that distract a viewer from any pile height variations that may exist in the toner image.
