Inkjet printing using pigmented and dye-based inks

摘要

An inkjet printing system and method for printing using both pigmented inks and dye-based inks. A supply of pigmented ink of a certain color is provided, along with another supply of dye-based ink of the same color. A pigmented nozzle array controllably deposits drops of the pigmented ink of the certain color, while a dye-based nozzle array controllably deposits drops of the dye-based ink of the same color. A region of a media is printed with the color by depositing, as governed by a controller, drops from the pigmented supply and drops from the dye-based supply on different subregions of the region.
