  • Patent number: 9016818
    Abstract: An ink jet recording method includes a first process in which a coloring ink is recorded on a recording medium using an ink jet head so as to form a first image, a second process in which a background ink is recorded using the ink jet head so as to form a background image that covers the first image, and a third process in which a coloring ink is recorded using the ink jet head so as to form a second image, and a drying process is included between the first process and the third process.

  • Patent number: 7784895
    Abstract: A liquid discharging apparatus includes upstream side nozzle group, a downstream side nozzle group, and a transport mechanism. The downstream side nozzle group is located on a downstream side in a transport direction as compared with the upstream side nozzle group. The transport mechanism transports a medium in the transport direction to the upstream side nozzle group and to the downstream side nozzle group. The upstream side nozzle group and the downstream side nozzle group each are formed of a plurality of nozzle columns that are arranged in the transport direction. Each of the nozzle columns is formed so that a plurality of nozzles that discharge liquid are arranged in a direction that intersects with the transport direction. A transport speed varies in accordance with the number of nozzle columns used.
