Abstract
The present disclosure is drawn to printing systems. In one example, a printing system can include a pretreatment head and an inkjet print head. The pretreatment head can include a surface barrier discharge 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.
Claims15
A printing system, comprising:
- a pretreatment head comprising a surface barrier discharge plasma generator to apply a plasma treatment to a media substrate;
- and
- an inkjet print head positioned with respect to the pretreatment head to form a printed image on the media substrate after the plasma treatment.
A method of forming a printed image on a media substrate, comprising:
- plasma treating a surface of a media substrate with a surface barrier discharge plasma generator;
- and
- jetting an inkjet ink from an inkjet print head onto the pretreated surface of the media substrate to form a printed image on the media substrate.
A printed article, comprising:
- a media substrate having a surface modified by surface barrier discharge plasma generator to form cationic species, oxygen containing groups, or a combination thereof on the surface, wherein the media substrate is substantially devoid of fixer;
- and
- a printed image formed by jetting an inkjet ink on the modified surface of the media substrate, wherein the printed image comprises pigment particles in contact with the modified surface of the media substrate.
