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.
Claims16
A method for producing a scratch-off structure, comprising:
- providing a substantially transparent plastic substrate at 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;
- and
- applying an opaque cover image ink layer upon the release ink layer.
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 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.
A memory resource storing instructions that when executed are to cause a processing resource to cause production of a scratch-off structure at 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.
