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.
Claims15
A printing system, comprising:
- a pretreatment head comprising a first plasma generator to apply a plasma treatment to a media substrate;
- 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 post-treatment head comprising a second plasma generator positioned with respect to the inkjet print head to treat the printed image on the media substrate;
- and
- wherein one or both of the first plasma generator or second plasma generator is a surface barrier discharge plasma generator.
A method of forming a printed image on a media substrate, comprising:
- plasma treating a surface of a media substrate;
- 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;
- and
- plasma treating the printed image after printing,
- wherein one or both of plasma treating the surface of the media substrate or plasma treating the printed image is performed utilizing a surface barrier discharge plasma generator.
A printed article, comprising:
- a media substrate having a surface modified by a first plasma generator to form cationic species, oxygen containing groups, or a combination thereof on the surface;
- 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, and wherein the inkjet ink comprises a polyurethane dispersion that has been cross-linked by exposure to free radicals generated by a second plasma generator, wherein one or both of the first plasma generator or second plasma generator is a surface barrier discharge plasma generator.
