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.
Claims12
A non-transitory memory resource storing machine- readable instructions stored thereon that cause a processor to:
- instruct a print engine to apply a primer layer on a first side of a substantially transparent substrate;
- instruct a print engine to apply a security ink layer to generate security information on the primer layer such that the security information is viewable from a second side of the substantially transparent substrate;
- and
- instruct a duplexer to return the substantially transparent substrate to the print engine to apply a release ink layer on the second side of the substantially transparent substrate.
A scratch-off structure, comprising:
- a substantially transparent substrate that includes a first side and a second side;
- a primer layer positioned on the first side of the substantially transparent substrate;
- a security ink layer to generate security information positioned on the primer layer such that the security information is viewable from the second side of the substantially transparent substrate;
- a first opaque background layer positioned on the security ink layer;
- a release ink layer positioned on the second side of the substantially transparent substrate, wherein the release ink layer includes a fatty acid ester having a plurality of hydroxyl substituents;
- and
- a second opaque background layer positioned on the release ink layer.
A system to cause production of a scratch-off structure at a printer, comprising:
- a duplexer component to alter a substantially transparent substrate from a first side to a second side to allow a print engine to apply layers on the first side and the second side;
- and
- a print engine to:
- apply a primer layer on the first side of the substantially transparent substrate;
- apply a security ink layer to generate security information on the primer layer such that the security information is viewable from the second side of the substantially transparent substrate;
- apply a first opaque background layer on the security ink layer;
- apply a release ink layer on the second side of the substantially transparent substrate;
- and
- apply a second opaque background layer on the release ink layer
- a corona discharge component to:
- apply a corona treatment to the second side of the substantially transparent substrate prior to the print engine applying the release ink layer on the second side of the substantially transparent substrate.
