    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: A recovery method for recovering proper operation of an ink jet recording head having a plurality of discharge ports and a plurality of thermal energy generating elements each corresponding to each of the discharge ports includes providing a recovery device for performing recovery according to a first recovery mode for only applying pressure to the discharge ports to effect suction of ink from the discharge ports while the discharge ports are capped by a capping device, and a second recovery mode for concurrently applying pressure to the discharge ports and driving the thermal energy generating elements to forcibly exhaust ink from the discharge ports while the discharge ports are capped by the capping means. The method also includes selectively performing recovery according to one of the first recovery mode and the second recovery mode.
