    摘要: An ink jet apparatus includes an ink jet head having in energy generator which car, generate energy employed for discharging ink as a droplet from a discharge port, and a control unit for controlling the energy generated from the energy generator so as to remove ink droplets, which adhere to a discharge port surface, by spreading the meniscus of the ink projecting from the discharge port on the discharge port surface. The apparatus is therefore capable of removing floating ink mist particles which adhere to the ink jet head.

    摘要: An ink jet recording apparatus and ink jet recording method record using different kinds of ink each having the same series color and a different density. The jet recording apparatus includes a converting unit for converting an input image density signal into an output image density signal, a binary unit for converting the output image density signal into binary data, an inverting unit for inverting the binary data, and a distributing unit for the binary data inverted and binary data to be inverted to drive data for an ink discharge unit and drive data for another ink discharge unit. Density unevenness and texture which arise from an image process, particularly a binary process, can be prevented. Different kinds of ink, each of which has the same series color and a different density, are respectively scanned so as not to overlap on the same pixel. Density unevenness due to ink soaking can be suppressed because different kinds of ink each having the same series color and a different density are not shot at the same position.

    摘要: An image formation apparatus provided according to the present invention does not generate any printing density streaks in low density areas of an image and is therefore capable of outputting stabilized images without any density unevennesses and density streaks in any tonality. The apparatus is structured so as to correct density signals in accordance with a correction table 1 for indicating the recording characteristics of each of the recording elements of the head and the recording characteristics indicated by this correction table 1, and to drive the recording head in accordance with a correction table 2, which does not allow the fore-going corrections to be made when the density signals are lower than a given density, and the density signals corrected by this correction table 2.
