    Abstract: The present disclosure is drawn to plasma treatment heads. In one example, a plasma head can include a dielectric barrier formed of a dielectric material. The dielectric barrier can have a treatment surface and an interior surface opposite of the treatment surface. A first electrode can be embedded within the dielectric barrier beneath the treatment surface. A second electrode can also be embedded within the dielectric barrier beneath the treatment surface and spaced laterally apart from the first electrode. A plurality of injection holes can penetrate through the dielectric plate from the interior surface to the treatment surface. The plurality of injection holes can be located between the first electrode and second electrode.

    Abstract: The present disclosure is drawn to printing systems. In one example, a printing system can include a pretreatment head, an inkjet print head, and a post-treatment head. The pretreatment head can include a first plasma generator to apply a plasma treatment to a media substrate. The inkjet print head can be positioned with respect to the pretreatment head to form a printed image on the media substrate after the plasma treatment. The post-treatment head can include a second plasma generator positioned with respect to the inkjet print head to treat the printed image on the media substrate.

    Abstract: The present disclosure is drawn to material sets, methods and printed articles and container supports. In one example, a material set can include a particulate fusible build material a particulate fusible build material having an average particle size ranging from about 0.01 μm to about 200 μm. The material set can also include a fusing ink including a fusing agent in a first liquid vehicle, wherein the fusing agent fuses the particulate fusible build material when exposed to electromagnetic energy or thermal energy. The material set can also include a binding ink including a binding agent in a second liquid vehicle, wherein the binding agent temporarily binds the particulate fusible build material when exposed to moderate temperatures ranging from ambient to 150° C.
