    Abstract: A method may include with a raster image processor, creating pretreatment plane rasterized image data from source image data and, with a plasma emitter, selectively applying a plasma treatment to a surface of a print media based on the pre-treatment plane rasterized image data. A printing device may include a raster image processor to execute an image analysis module to create pre-treatment plane rasterized image data from source image data and a plasma emitting device to selectively apply a plasma treatment to a surface of a print media based on the pre-treatment plane rasterized image data.

    Abstract: The present disclosure is drawn to printing systems. In one example, a printing system can include an electrode having a plurality of electrode protrusions associated therewith and a conductive plate. The electrode and conductive plate can be positioned with respect to one another to generate an electric field therebetween and to allow a media substrate to be positioned therebetween to be exposed to the electric field. Additionally, an inkjet print head can form a printed image on the media substrate after exposure to the electric field.

    Abstract: In an embodiment, an ink erasing system includes an erase fluid dispenser to apply erase fluid to a surface of a print medium. The system includes a plurality of nonadjacent pairs of electrodes positioned across a width of the print medium. The system also includes a controller to direct the erase fluid dispenser to apply the erase fluid in an erase region on the print medium, and to alternately electrify the nonadjacent pairs of electrodes to generate a moving electric field through the erase region.
