    Abstract: A printing system (30, 40, 40′, 50, 50′) includes at least one ejector coupled to a reservoir (38) that is configured to contain a printing composition including a hydrocarbon having at least one unsaturated bond. The hydrocarbon is configured to at least one of polymerize or crosslink in the presence of a reactive species. The at least one ejector is configured to eject the printing composition onto a surface (34, 36, 10). The system (30, 40, 40′, 50, 50′) further includes a corona generator (32, 32′, 32″, 32′″) configured to generate the reactive species in situ. The corona generator (32, 32′, 32″, 32′″) is positioned with respect to the reservoir (38) such that the reactive species is exposed to the printing composition after the printing composition has been ejected onto the surface (34, 36, 10). The polymerizing and/or the cross-linking of the hydrocarbon is configured to form a polymer matrix (12) from the ejected printing composition.

    Abstract: A method of forming ionically-charged, colorant nanoparticles involves forming in-situ ionically-charged polyurethane monomers, and forming an emulsion including the ionically-charged polyurethane monomers and a colorant nanoparticle. The method further involves polymerizing or crosslinking the ionically-charged polyurethane monomers in the emulsion, where the polymerizing or crosslinking chemically attaches the ionically-charged polyurethane monomers to a surface of the colorant nanoparticle to form an ionically-charged encapsulation layer on the surface.

    Abstract: An ink forming method involves preparing a deagglomerated ink or a modified deagglomerated ink. The deagglomerated ink or the modified deagglomerated ink includes at least deagglomerated colorant particles and a liquid component. The deagglomerated colorant particles are chosen from pigment particles each encapsulated with a dispersant. The colorant particles have a particle size ranging from about 50 nm to about 500 nm. Prior to shipping and/or storing the deagglomerated ink or the modified deagglomerated ink, a portion of the liquid component is removed to form a concentrated ink that has a nonvolatile solids content ranging from about 40 wt % to about 90 wt % of the concentrated ink.

    Abstract: An ink composition includes a particulate pigment, a hydrocarbon vehicle, an organic polyamine and an organic polyacid. A ratio by weight percent of the organic polyamine to the organic polyacid in the hydrocarbon vehicle is sufficient to render a conductivity of the ink composition to equal to or less than 15 nanosiemens per centimeter. The ink composition is prepared by combining the particulate pigment with a composition that includes the hydrocarbon vehicle, the organic polyamine and the organic polyacid. The combination is subjected to conditions under which the particulate pigment becomes dispersed in the composition.
