Abstract
An image formation device includes at least one frame portion supporting at least one emitter to emit airborne charges, at least one radiation element to emit radiation, and a fluid ejection device to deposit droplets of ink particles within a non-aqueous fluid carrier onto a substrate. Upon relative movement between the at least one frame portion and the substrate, the emitted airborne charges are to electrostatically fix, and the at least one radiation element is to emit radiation to cause at least further fixation of, the deposited particles relative to the substrate.
Claims15
An image formation device comprising:
- at least one frame portion:
- a fluid ejection device supported by the frame portion and configured to deposit droplets of ink particles and resin within a non-aqueous fluid carrier onto a substrate to at least partially form an image on the substrate;
- at least one emitter supported by the at least one frame portion and configured to, upon relative movement between the frame portion and the substrate, emit airborne charges to fixate the ink particles onto the substrate by causing the ink particles to move, via attraction relative to the substrate, through the fluid carrier toward the substrate to electrostatically fix the ink particles relative to the substrate;
- and
- at least one radiation source supported by the at least one frame portion and configured to emit radiation to further fixate the ink particles onto the substrate by polymerizing the resin to chemically fix the ink particles relative to the substrate.
An image formation device comprising:
- a conveyance element to move a substrate along a travel path;
- a fluid ejection device configured to deposit droplets of ink particles and resin within a dielectric, non-aqueous fluid carrier onto the substrate to form at least a portion of an image on the substrate;
- at least one charge source configured to emit airborne charges to fixate the ink particles onto the substrate by causing the ink particles to move, via attraction relative to the substrate, through the fluid carrier toward the substrate to electrostatically fix the ink particles relative to the substrate;
- at least one radiation source configured to further fixate the ink particles onto the substrate by at least partially polymerizing the resin to chemically fix the ink particles relative to the substrate.
A method of image formation comprising:
- providing at least one frame portion supporting at least one charge source, at least one radiation source to emit radiation, and a fluid ejection device;
- performing relative movement between the at least one frame portion and a substrate;
- while performing the relative movement, depositing droplets of ink particles and resin within a non-aqueous fluid carrier from the fluid ejection device onto the substrate to at least partially form an image on the substrate;
- while performing the relative movement, and after the droplets have been deposited, emitting airborne charges from the at least one charge source to fixate the ink particles onto the substrate by causing the ink particles to move, via attraction relative to the substrate through the fluid carrier toward the substrate to electrostatically fix the ink particles relative to the substrate;
- and
- while performing the relative movement, and after emitting the airborne charges, emitting radiation from the at least one radiation source to further fixate the ink particles onto the substrate by polymerizing the resin to chemically fix the ink particles relative to the substrate.
