Title:
インクジェットプリンタ用パレット選択方法
Document Type and Number:
Japanese Patent JP3561521
Kind Code:
B2
Abstract:
The invented method involves the coding of color and black print image data for communication of the same from a printer server or driver to an ink-jet printer. The coding is such that true black or process black can be selected by the driver and can be used by a printer capable of producing both, i.e. an ink-jet printer equipped with a black ink pen and a tri-color ink pen. An invented print protocol permits one of a variety of color palettes to be selected on a print page basis. If the selected palette includes true black (K), then, for areas wherein only true black will be printed, the communication sequence in which the codes are sent to the printer requires none of the color selection coding. A four-plane, as well as other, palettes are described, with the four-plane palette including true black (K), cyan (C), magenta (M) and yellow (Y). Each of the four color planes in each palette is assigned a unique binary bit by the preferred coding method, thereby simplifying and reducing coding and decoding overhead for both the driver and the printer.
