    摘要: Described is a color inkjet printer for optimum bleed prevention in a printer utilizing multiple black and color pens wherein there is provided one print cartridge for dispensing black ink onto the printing medium and at least one print cartridge for dispensing color ink onto the printing medium. The cartridge for dispensing black ink contains an ink with little or no surface active agent while the cartridge for dispensing color ink contains a sufficient amount of surface active agent to reduce bleed between the colors. Moreover, the cartridge for dispensing black ink contains an ink which reacts with at least one and more preferably all inks contained in the cartridge for dispensing color ink. This reaction reduces bleed on images where the black print is adjacent to the color print to an acceptable level without requiring the black ink to contain surface active agents that would lead to inferior quality black text on the plain paper print medium. The reaction may be initiated by pH changes, reaction between the actual colorants, or reaction between one of the colorants and a component in the other ink.

    摘要: Ink and fixer compositions for printing on hydrophobic media. The ink compositions include a water soluble dye and a vehicle, the vehicle includes water, a glycol ether, a humectant, and a non-ionic surfactant. The fixer compositions include a fixing agent and a vehicle, the vehicle includes water, a glycol ether, a humectant, and a non-ionic surfactant. Methods of printing on hydrophobic media. The methods include the steps of providing an ink that includes a water soluble dye and a vehicle, the vehicle including water, a glycol ether, a humectant, and a non-ionic surfactant; providing a hydrophobic print medium; and depositing the ink on the hydrophobic print medium. The method of printing may further include steps of applying heat to the hydrophobic print medium during and/or after the ink deposition step. The method of printing may yet further include steps of providing a fixer that includes a fixing agent and a vehicle, the vehicle including water, a glycol ether, a humectant, and a non-ionic surfactant; and depositing the fixer on the hydrophobic print medium before, after, or both before and after the ink is deposited.

    摘要: A fixer fluid having reduced kogation. The fixer fluid includes at least one phosphate ester surfactant and at least one cationic polymer, wherein the fixer fluid is formulated so that the at least one phosphate ester surfactant does not precipitate with the at least one cationic polymer. The at least one phosphate ester surfactant may be an anionic phosphate ester surfactant or an amphoteric phosphate ester surfactant. If the at least one phosphate ester surfactant is an anionic phosphate ester surfactant, it may have greater than or equal to approximately 2 moles of ethylene oxide per mole of the phosphate ester surfactant. The present invention also relates to an inkjet ink having reduced kogation and a method of producing a fixer fluid having reduced kogation.

    摘要: The present invention provides a dynamic adjustment of the printed fluid volume for underprinting and/or overprinting pigment-based inks (or other inks) for speeding up the drying time of the pigment-based ink or improving its adherence to a medium. The invention identifies a characteristic in the printer that affects the optimum volume of under/overprinted fluid to be printed, such as pen temperature, operating frequency, operating life, ambient temperature, and ambient humidity, and varies the printed volume of the under/overprinted fluid accordingly.
