Abstract
An image formation device includes a support, a fluid ejection device, and a first porous element. The support is to support movement of a substrate along a travel path, while the fluid ejection device is located along the travel path to deposit droplets of ink particles within a liquid carrier onto the substrate to at least partially form an image on the substrate. The first porous element is located downstream along the travel path from the fluid ejection device to be in contact against the substrate to remove, via electroosmotic flow through the first porous element, at least a portion of the liquid carrier from the substrate.

An image formation device comprising:
- a support to support movement of a substrate along a travel path;
- a fluid ejection device along the travel path to deposit droplets of ink particles within a liquid carrier onto the substrate to at least partially form an image on the substrate;
- and
- a first porous element located downstream along the travel path from the fluid ejection device to be in contact against the substrate to remove, via electroosmotic flow through the first porous element, at least a portion of the liquid carrier from the substrate.
An image formation device comprising:
- a support to support movement of a substrate along a travel path;
- a fluid ejection device along the travel path to deposit droplets of ink particles within a liquid carrier onto the substrate to at least partially form an image on the substrate;
- and
- a first porous element downstream along the travel path from the fluid ejection device;
- a contact zone in which the first porous element is to be in movable contact against the substrate, during application of an electric field across the substrate and the first porous element, to cause electroosmotic flow of the liquid carrier through the first porous element to remove at least a portion of the liquid carrier from the substrate.
A method comprising:
- moving a substrate along a travel path;
- depositing, via a fluid ejection device, droplets of ink particles within a liquid carrier onto the substrate to at least partially form an image on the substrate;
- and
- engaging the substrate with a first porous element, while applying an electric field across the substrate and a belt, to cause electroosmotic removal of at least a portion of the liquid carrier from the substrate.
