  • Patent number: 8440010
    Abstract: In an inkjet recording system using an ink in which a coloring material is dispersed in a solvent with a dispersing agent, printing density is improved by causing aggregation of the coloring material contained in the ink that has been ejected onto a printing medium. In an inkjet printing method, printing is performed by ejecting one of first and second inks onto a printing medium, and then successively ejecting the other ink so as to overlay it on the one ink. The first ink includes a first solvent, a coloring material, and a dispersing agent. The second ink includes at least a second solvent capable of changing solubility of the dispersing agent to cause aggregation of the coloring material when it is mixed with the first ink. For example, when one of the first and second solvents includes a water-insoluble organic solvent, the other can include a water-soluble organic solvent.

    Abstract: An inkjet printer includes an inkjet printhead having a plurality of color planes for ejecting a plurality of different inks. Each color plane has a nozzle row defined in a nozzle face of the printhead and each nozzle in a respective color plane is supplied with a same ink. The printhead is plumbed such that a first color plane ejecting a first ink having a relatively low luminance is sandwiched between second and third color planes ejecting respective second and third inks having a relatively high luminance A plurality of ink reservoirs are in fluid communication with the printhead, the ink reservoirs containing the first, second and third inks. An amount of surfactant in the first ink is at least 0.4 wt % greater than an amount of surfactant in the second and third inks.
