Abstract
The present disclosure is drawn to printing systems. In one example, a printing system can include a first excimer irradiation source positioned to irradiate a media substrate. Additionally, an inkjet print head can be positioned with respect to the excimer irradiation source to form a printed image on the media substrate after irradiation with the excimer irradiation source.
Claims14
A printing system, comprising:
- a first excimer irradiation source positioned to irradiate a media substrate, wherein the first excimer irradiation source has power metrics and is posited at a distance from the media substrate to provide electromagnetic radiation at the surface of the media substrate at a surface power density of from 20 mW/cm2 to 80 mW/cm2 and
- an inkjet print head positioned with respect to the excimer irradiation source to form a printed image on the media substrate after irradiation with the excimer irradiation source.
A method of forming a printed image on a media substrate, comprising:
- pre-treating a portion of a surface of a media substrate with electromagnetic radiation emitted from a first excimer irradiation source, wherein the first excimer irradiation source has power metrics and is posited at a distance from the media substrate to provide electromagnetic radiation at the surface of the media substrate at a surface power density of from 20 MW/cm2 to 80 mW/cm2;
- and
- jetting an inkjet ink from an inkjet print ad onto the media substrate to form a printed image on the portion.
A system for a printed article, the printed article comprising:
- a media substrate having a modified surface formed by exposure to electromagnetic radiation emitted from a first excimer irradiation source to form cationic species, acid groups, oxygen containing groups, or a combination thereof on the surface, wherein the media substrate is substantially devoid of printed fixer,
- wherein the first excimer irradiation source has power metrics and is posited at a distance from the media substrate to provide electromagnetic radiation at the surface of the media substrate at a surface power density of from 20 mW/cm2 to 80 mW/cm2;
- and
- a digitally printed image on the modified surface, including pigment particles in contact with the modified surface of the media substrate.
