Abstract

A scratch-off document may include a substrate. The substrate may include a front side and a backside with an information layer on the front side. An information layer may include an indicia component and a noise component. The noise component together with the indicia component may include a plurality of pile heights, and the indicia component may be visible when combined with the noise component. A scratch-off layer is included over the information layer so that the indicia component is not recognizable through the scratch-off layer.

Claims

1. A scratch-off document, comprising

a substrate comprising a front side and a backside;

an information layer on the front side, comprising;

an indicia component; and

a noise component;

wherein the noise component together with the indicia component comprise a plurality of pile heights;

wherein the indicia component is visible when combined with the noise component; and

a scratch-off layer over the information layer, wherein the indicia component is not recognizable through the scratch-off layer.

2. The document of claim 1 wherein the information layer comprises a toner.

3. The document of claim 1, wherein information layer comprises a halftone print.

4. A the document of claim 1, wherein the noise component comprises one or more of a dithered ink or an overlapping ink.

5. The document of claim 1, wherein the scratch-off layer comprises a phase-change ink.

6. The document of claim 1, wherein the scratch-off layer comprises a substantially transparent layer adjacent to the information layer and a substantially opaque layer over the substantially transparent layer.

7. The document of claim 1, wherein the information layer comprises a plurality of non-inked substrate areas;

wherein the scratch-off layer comprises a substantially transparent layer adjacent to the information layer and a substantially opaque layer over the substantially transparent layer; and

wherein a portion of the substantially transparent layer is in contact with at least a portion of the plurality of non-inked substrate areas.

8. The document of claim 1, wherein the scratch off layer comprises an image.

9. The document of claim 1, further comprising an infrared security component.

10. A method, comprising:

printing an information layer on a substrate, comprising printing an indicia component and printing a noise component;

wherein printing the noise component and printing the indicia component comprise printing a plurality of pile heights, and wherein the indicia component is optically visible in combination with the noise component; and

printing a scratch-off layer, wherein the indicia component is not recognizable through the scratch-off layer.

11. The method of claim 10, wherein the printing of the information layer comprises electrostatographic printing.

12. The method of claim 10, wherein the printing of the information layer comprises halftone printing.

13. The method of claim 10, wherein printing the indicia component comprises printing a plurality of indicia pile heights.

14. The method of claim 10, wherein the printing of the scratch-off layer comprises phase-change ink printing.

15. The method of claim 10, wherein printing the scratch-oft layer comprises printing a substantially transparent layer adjacent to the information layer and a substantially opaque layer over the substantially transparent layer.

16. The method of claim 10, wherein printing of the information layer results in a plurality of non-inked substrate areas;

and wherein printing the scratch-off layer comprises printing a substantially transparent layer adjacent to the information layer and a substantially opaque layer over the substantially transparent layer; and

wherein a portion of the substantially transparent layer is in contact with at least a portion of the plurality of non-inked substrate areas.

17. A method, comprising:

electrostatographically printing an information layer on a substrate, comprising;

electrostatographically printing a halftone indicia component and electrostatographically printing a halftone noise component;

wherein printing the noise component together with printing the indicia component comprise printing a plurality of pile heights, and wherein the indicia component is optically visible in combination with the noise component; and

phase-change ink printing a removable scratch-off layer, wherein the indicia component is not recognizable under the removable scratch-off layer.

18. The method of claim 17, wherein one or more of printing the noise component or printing the indicia component comprises printing one or more of dithered ink or overlapping ink.

19. The method of claim 17, wherein printing of the scratch-off layer comprises printing a substantially transparent layer adjacent to the information layer and a substantially opaque layer over the substantially transparent layer.

20. The method of claim 17, wherein printing the information layer comprises printing that results in a plurality of non-inked substrate areas;

and where printing the scratch-off layer comprises printing a substantially transparent layer adjacent to the information layer and a substantially opaque layer over the substantially transparent layer;

wherein an ink from the substantially transparent layer is in contact with at least a portion of the plurality of non-inked substrate areas.
