1. A scratch-off document comprising:
- a substrate;
a toner layer printed on the substrate, the toner layer comprising a plurality of background layer pixels of a toner having a first color and a plurality of messaging layer pixels of a toner having a second color, wherein the first pixels and the second pixels are positioned in a side-by-side relation; and
a scratch-off layer covering the toner layer, the scratch-off layer comprising;
a first mass of a first solid ink that covers the messaging layer pixels,a second mass of a second solid ink printed over or under the first mass in a distraction pattern so that the scratch-off layer exhibits a non-uniform pile height and does not provide a uniform surface.

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.

9. A document comprising:
-
a substrate; a toner image printed on the substrate, the toner image comprising a plurality of background layer pixels of a toner having a first color and a plurality of messaging layer pixels of a toner having a second color, wherein the background layer pixels and the messaging layer pixels pixels are positioned in a side-by-side relation so that the toner image exhibits an average thickness; and a substantially opaque solid ink image covering the toner image, the solid ink image comprising; a first mass of a solid ink that covers the messaging layer pixels, a second mass of a solid ink printed in a distraction pattern over or under at least a portion of the first mass so that the solid ink image exhibits a non-uniform pile height and does not provide a uniform surface, wherein; the distraction pattern exhibits an average thickness that is at least as large as the average thickness of the toner image, and the second solid ink and the messaging layer pixels comprise different shades of the same color; and wherein the toner image exhibits a property of adhesion to the substrate that is substantially higher than a property of adhesion of the solid ink image, such that the solid ink image may be removed from the substrate by scratching with a hard object without removing the toner layer. - View Dependent Claims (10, 11, 12, 13, 14, 15, 19, 20)

16. A method of printing a scratch-off document, the method comprising:
-
printing a toner layer by; printing a message on a substrate, the message comprising a plurality of pixels of a first toner, and printing a background on the substrate at positions adjacent to the pixels of the message; printing a first layer of a solid ink onto the toner layer, wherein the first layer has a substantially even thickness; and printing a second layer of a solid ink over the first layer so that second layer exhibits a distraction pattern, so that the first layer and the second layer form a scratch-off layer having a textured surface. - View Dependent Claims (17, 18)
