Abstract

In one example of the disclosure, a substantially transparent substrate is provided at a printer. A primer layer is applied upon a first surface of the substrate. A security ink layer that includes security information is applied upon the primer layer. An opaque background ink layer is applied upon the security ink layer. A corona treatment is applied to a second surface, located on an opposite side of the substrate relative to the first surface. A release ink layer is applied upon the corona-treated second surface. An opaque cover image ink layer is applied upon the release ink layer.

First claim

What is claimed is:

1. A method for producing a scratch-off structure, comprising:
providing a substantially transparent plastic substrate by a printer;
applying a primer layer upon a first surface of the substrate;
applying a security ink layer that includes security information upon the primer layer;
applying an opaque background ink layer upon the security ink layer;
applying a corona treatment to a second surface, located on an opposite side of the substrate relative to the first surface;
applying a release ink layer upon the corona-treated second surface;
applying an opaque cover image ink layer upon the release ink layer;
wherein each of the security ink layer, the opaque background ink layer, and the opaque cover image layer includes a colored ink, and
wherein the release ink layer includes an ink with release properties such that, when the opaque cover image ink layer is scratched with a hard surface, the release ink layer and the opaque cover image layer break into fragments to reveal the substantially transparent substrate, and the security information of the security ink layer becomes visible through the substantially transparent plastic substrate.

2. The method of claim 1 , wherein each of the security ink layer, the opaque background ink layer, the release ink layer, and the opaque cover image layer includes an electrostatic ink applied at the printer.

3. The method of claim 1 , wherein applying the security ink layer includes creating an image in mirror-image format.

4. The method of claim 1 , wherein applying the opaque background ink layer includes creating an image in mirror-image format.

5. The method of claim 1 ,
wherein the printer includes a duplexer component, and
wherein the printer applies the primer layer, applies the security ink layer, and applies the opaque background ink layer occur as sequential impressions upon a first side of the substantially transparent substrate, and
wherein the printer applies the release ink layer and applies the opaque cover image ink layer occur as sequential impressions upon a second side of the substrate.

6. The method of claim 5 , wherein the substantially transparent substrate is a sheet substrate, and wherein the printer applies sequential impressions upon the first side of the substrate and applies sequential impressions upon the second side of the substrate utilizing a same print engine.

7. The method of claim 5 , wherein the substantially transparent substrate is a web substrate, and wherein the printer applies sequential impressions upon the first side of the substrate utilizing a first print engine and applies sequential impressions upon the second side of the substrate utilizing a second print engine in line with the first print engine.

8. A scratch-off structure comprising the following layers in order:
a first layer including a first opaque image;
a second layer including security information;
a third layer that is a primer layer applied upon a first surface of a substantially transparent substrate;
a fourth layer that is the substantially transparent plastic substrate;
a fifth layer that is a release layer; and
a sixth layer that includes a second opaque image;
wherein the substantially transparent substrate has a second surface on an opposite side of the substrate relative to the first surface, and wherein the second surface is a corona-treated surface.

9. The scratch-off structure of claim 8 , wherein each of the first layer, the second layer, and the sixth layer includes a colored electrostatic ink.

10. The scratch-off structure of claim 8 , wherein the sixth layer includes a colored electrostatic ink, and wherein the fifth layer includes an electrostatic ink with release properties such that, when the sixth layer is scratched with a hard surface, the fifth and sixth layers break into fragments to reveal the substantially transparent fourth layer.

11. The scratch-off structure of claim 8 , wherein the fifth layer includes an additive that causes the fifth layer to be more removable, relative to electrostatic inks of the first layer and the sixth layer, when exposed to a mechanical force, the additive including at least one from the set of a fatty acid ester having a plurality of hydroxyl substituents, a fatty acid amide having a plurality of hydroxyl substituents, and a mixture of fatty acid esters, and a mixture of fatty acid amides.

12. A memory resource storing instructions that when executed are to cause a processing resource to cause production of a scratch-off structure by a printer, comprising:
a first surface module that when executed
causes application of a primer layer upon a first surface of substantially transparent plastic substrate;
causes application of a security electrostatic ink layer that includes security information upon the primer layer;
causes application of an opaque background electrostatic ink layer upon the security electrostatic ink layer;

a second surface module that when executed
causes application of a corona treatment to a second surface, located on an opposite side of the substrate relative to the first surface;
causes application of a release electrostatic ink layer upon the corona-treated second surface; and
causes application of an opaque cover image electrostatic ink layer upon the release electrostatic ink layer.

13. The memory resource of claim 12 ,
wherein each of the security electrostatic ink layer, the opaque background electrostatic ink layer, and the opaque cover image electrostatic layer is to include a colored ink, and
wherein the release electrostatic ink layer includes an ink with release properties such that, when the opaque cover image electrostatic ink layer is scratched with a hard surface, the release electrostatic ink layer and the opaque cover image electrostatic layer break into fragments to reveal the substantially transparent substrate, and the security information of the security ink electrostatic layer becomes visible through the substantially transparent plastic substrate.
