摘要： An imaging member comprising a substrate, an electrically insulating swellable, softenable layer on the substrate, the softenable layer having particulate migration marking material located at least at or near the surface of the softenable layer spaced from the substrate, and a protective overcoating comprising a film-forming resin, a portion of which extends beneath the surface of the softenable layer. This migration imaging member may be prepared with the aid of a material which swells at least the surface of the softenable layer to allow the film-forming resin to penetrate beneath the surface of the softenable layer.

摘要： Methods of leveling ink on substrates and apparatuses useful in printing are provided. An exemplary embodiment of the methods includes irradiating ink disposed on a first surface of a porous substrate with radiation emitted by at least one flash lamp. The radiation flash heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the first surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate from the first surface.

摘要： A method of leveling a curable phase-change ink on a surface includes printing the curable phase-change ink onto a transfer surface, pressing the transfer surface onto a print substrate with sufficient pressure to level the ink, and exposing the curable phase-change ink to radiation through the transfer surface to cure the phase-change ink. A method for leveling a region of a printed surface includes printing curable phase-change ink onto a surface, pressing a leveling surface onto the print surface to contact a region of the curable phase-change ink, and exposing the curable phase-change ink through the leveling surface to radiation to cure the phase-change ink.

摘要： A system for heated gas fusing of toner on non-porous substrates is provided. The system uses (1) an extended fusing zone held at lower temperatures than needed for a roll nip or radiant fuser, and (2) a very low melt toner which can be fused at greatly reduced temperatures compared to conventional toners. In one form, the system is realized through (a) the use of heated gas as the low temperature extended zone fusing technology, and (b) the use of ultra-low melt (ULM) toner—which requires significantly reduced temperature compared to conventional toner. On non-porous packaging substrates the use of heated gas can limit the substrate temperature to 100° C.

摘要： Alignment of an ejector module in a printhead is achieved along a lateral direction by arranging first and second partially overlapping pluralities of nozzles, determining an alignment pair between first and second nozzles within their respective pluralities, and assigning the alignment pair as boundaries for print actuation. The first and second ejector modules are disposed in a printhead array along a lateral direction and include first and second nozzles eject fluid on command. The first nozzles are disposed with a first spacing therebetween in the first ejector module. The second nozzles at one end of the second ejector module that overlap the first nozzles are disposed with a second spacing that differs from the first spacing. An alignment pair between first and second nozzles of their respective pluralities is determined to minimize an alignment spacing between each other as compared to remaining nozzles. The first and second alignment nozzles are assigned as first and second boundaries for print actuation.

摘要： A marking apparatus is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Marking material, such as ink, toner, etc., is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. At sufficient velocity, and with appropriate marking material, the marking material may be kinetically fused to the substrate. A multiplicity of channels for directing the propellant and marking material allow for high throughput, high resolution marking. Multiple marking materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.
