Abstract: The present invention is drawn to ink-jet ink compositions, methods, and systems for increasing the bleed and smear fastness and optical density of a printed image. Specifically, an aqueous ink-jettable ink composition is disclosed which exhibits a decrease in pH upon exposure to radiation, followed by precipitation of the ink colorant. The composition can include an ink vehicle, an effective amount of an ink colorant having pH dependent solubility properties, and an effective amount of a photo-initiated acid generator. The method includes the steps of formulating the composition, jetting the ink composition from an ink-jet pen onto a substrate, and exposing the ink-jetted ink on the substrate to radiation wherein the ink-jet ink composition exhibits reduced pH, followed by precipitation of the colorant. Additionally, the system can include an ink-jet ink pen containing the ink-jettable ink composition, a substrate configured for accepting a printed image from the ink-jet pen, and an energy source configured for irradiating the printed image such that a decrease in pH is realized resulting in precipitation of the ink colorant.

Abstract: An ink jet inkset is provided for image printers, in particular large format printers, for printing on both porous, non-porous, and hybrid glossy media. The inket contains a black ink and one or more color inks, said color ink composition comprises at least one water-soluble dye and a vehicle comprising at least one co-solvent and at least two different surfactants, a non-ionic surfactant and a fluoro-surfactant. The total surfactant concentration ranges from about 0.05 to 6 wt % of the ink composition. The non-ionic surfactant is present in a range of about 0.05 to 3 wt % of the ink composition, while the fluoro-surfactant is present in a range of about 0.001 to 3 wt % of the ink composition. The ink formulation that works well with porous, non-porous, and hybrid glossy media and provides substantially instant ink drying and light fastness of the ink. Further, the ink formulation evidences excellent image quality. The ink can also pass harsh pen material compatibility tests. The ink does not puddle on the surface of the orifice plate in the default pen, yet has low viscosity. The ink is excellent in pen reliability such as long decap time, no decel, no kogation, and good drop directionality.

Abstract: At least one of the following compounds is included on a surface layer of a print medium and in an inkjet ink formulation to be printed thereon: potassium iodide, sodium iodide, sodium thiosulfate, potassium thiosulfate, and sodium thiocyanate. The addition of at least one of these compounds to both the print medium and the inkjet ink can improve light fastness on the order of eight to thirteen times or more on porous glossy media. These additives are particularly effective with water-soluble dyes, including such dyes as Reactive Black 31 (Pacified) (RB31), Direct Blue 199 (DB199), Magenta 377 (M377), and Direct Yellow 132 (DY132).
