    摘要: Throughput of ink jet printers can be increased by using multiple print heads, each of which independently prints an image or text on a continuous roll of print media. Independently controlled printer carriages supporting the print heads simultaneously print images onto media since the printer carriages are separated by a distance that is substantially to equal to at least one dimension of the image to be printed.

    摘要: A first roller has a first roller center line; a second roller has a second roller center line. Fluid-ejection mechanisms eject fluid onto the media as the media is rolled past the rollers, and include first mechanisms and second mechanisms. The first mechanisms include first and second printheads, at least substantially equally between which a first positioning line is defined. The second mechanisms include third and fourth printheads, at least substantially equally between which a second positioning line is defined. The fluid-ejection mechanisms are disposed opposite to the roller and are positioned such that the first and second positioning lines are located between the first and second roller center lines, the first and the third printheads are not completely located between the first and the second roller center lines, and the second and the fourth printheads are completely located between the first and the second roller center lines.

    摘要: A multiple ink jet printing system comprising a plurality of rows of dark dye nozzles and light dye nozzles. Each row of dark dye nozzles is coupled to a supply of dark dye ink, and each row of light dye nozzles is coupled to a supply of light dye ink. Each of the rows of dark dye nozzles and light dye nozzles are arranged substantially parallel to each other, and at least one row of dark dye nozzles is separated from the next row of dark dye nozzles by at least one row of light dye nozzles.

    摘要: The present invention is a single-pass, bi-directional printer where two color maps are being employed. One color map is used for left to right printing and the second color map is used for printing right to left. The use of two color maps allows the quantity and placement of individual ink droplets to be adjusted, according to their order of application, to minimize the directional related color hue shift typically experienced with bi-directional inkjet printers.
