Abstract

A device comprising a supply, a first portion, a second portion, and a third portion. The supply is to supply a metallized, non-absorptive media along a travel path, which is electrically connectable to a ground element, the metallized media to carry a first polymer structure. The first portion along the travel path is to receive droplets of ink particles within a dielectric, non-aqueous carrier fluid on the first polymer structure on the media to form an image. The second portion is to apply an adhesion-promoting surface treatment, onto the ink particles and the first polymer structure, comprising UV ozone, plasma, or chemical additive. The third portion is to apply, via heat and pressure, a second polymer structure onto the ink particles and the first polymer structure to produce a media assembly.

First claim

a supply to supply a metallized, non-absorptive media along a travel path, which is electrically connectable to a ground element, the metallized media to carry a first polymer structure;
a first portion along the travel path to receive droplets of ink particles within a dielectric, non-aqueous carrier fluid on the first polymer structure on the media to form an image; and
a second portion to apply an adhesion-promoting surface treatment onto the ink particles and the first polymer structure, the surface treatment comprising an UV ozone treatment, a plasma treatment, or a chemical treatment; and
a third portion to apply, via heat and pressure, a second polymer structure onto the ink particles and the first polymer structure to produce a media assembly.

2. The device of claim 1 , wherein the plasma treatment comprises one of an atmospheric corona discharge treatment, an oxygen plasma treatment, a nitrogen plasma treatment, and argon plasma treatment.

3. The device of claim 1 , wherein the chemical treatment comprises at least one of a silane treatment, a titanate treatment, and a zirconate material.

4. The device of claim 1 , wherein the adhesion-promoting surface treatment is to substantially increase a peel-strength of the second polymer structure relative to the both the first polymer structure and the ink particles of the media assembly.

5. The device of claim 1 , comprising:
a fourth portion upstream from the first portion to receive an electrically charged, semi-liquid image-receiving holder onto the media, wherein the image-receiving holder comprises a binder material and the droplets are substantially binder-material-free, and wherein the image-receiving holder comprises at least a portion of the first polymer structure.

6. The device of claim 5 , comprising:
a fifth portion between the first portion and the second portion, and including a charge generation portion to emit airborne charges to charge the ink particles to move, via attraction relative to the grounded media, through the carrier fluid toward the media to become electrostatically fixed relative to the first polymer structure and the media.

7. The device of claim 1 , wherein the first portion comprises a receiving structure to removable receive a fluid ejection device, which comprises a drop-on-demand fluid ejection device to eject the droplets of ink particles within the dielectric carrier fluid to be received on the non-absorptive media.

8. The device of claim 1 , comprising at least one of:
a first liquid removal portion downstream along the travel path from the first portion to mechanically remove at least a portion of the carrier fluid from the media; and
a second liquid removal portion downstream from the first liquid removal portion and including:
a heated air element to direct heated air onto at least one of the carrier fluid and the media; or
a radiation device to direct at least one of IR radiation and UV radiation onto at least the carrier fluid and media.

9. A device comprising:
a control portion;
a media supply to supply a non-absorptive media along a travel path and to which a ground element is to be electrically connected; and
a series of stations arranged along the travel path of the media in which each station is to provide one color ink of a plurality of different color inks onto the media, and wherein each station comprises:
a first portion in which the control portion is to cause a fluid ejection device to deliver droplets of ink particles within a dielectric, non-aqueous carrier fluid on the media to form at least a portion of an image; and
a second portion including a charge generation portion to emit airborne charges to charge the delivered ink particles, via attraction relative to the grounded media, to move through the carrier fluid toward the grounded media to become electrostatically fixed relative to a first polymer structure and media; and

a third portion to apply a peel-strength-promoting surface treatment, onto the ink particles and the first polymer structure, the surface treatment comprising an UV ozone treatment, a plasma treatment, or a chemical treatment, the chemical treatment comprising at least one of a silane material, a titanate material, and a zirconate material; and
a fourth portion to apply heat and pressure to secure a second polymer structure to the ink particles, the first polymer structure, and the grounded media to produce a media assembly comprising the formed image.

10. The device of claim 9 , comprising:
a fifth portion upstream from the first portion to receive an electrically charged, semi-liquid image-receiving holder onto the grounded media prior to receipt of droplets, wherein the image-receiving holder comprises a binder and the droplets are substantially binder free.

11. The device of claim 9 , comprising:
at least one liquid removal portion downstream from at least a last respective station and including at least one of:
a mechanical removal structure to physically remove carrier fluid on the first polymer structure and the media; and
an energy transfer mechanism to cause evaporation of carrier fluid on the first polymer structure and the media.

12. A method comprising:
