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： In forming an image with plural recording heads corresponding to plural inks of different densities, the image data are so distributed that the image is formed with the ink of low density until the image density reaches a predetermined density level, but is formed with the inks of low and high densities when the image density exceeds the predetermined density level, and the distributed data are corrected according to the detection of temperature relating to the recording heads, whereby a desired recorded image can be obtained even in the presence of a variation in the head temperature. Also the image data are distributed in such a manner that, when the remaining amount of one of the plural inks becomes low, the recording is conducted with the remaining ink, whereby a desired image can be obtained even when the remaining amount of one of the plural inks with different densities becomes low.

摘要： An ink jet recording apparatus which performs recording using a plurality of types of inks which are different in nature such as level of thickness, improved to attain excellent gradation of recorded image with a reduced number of ink types which are prepared beforehand. In one form, a clear ink which does not contain any dye is mixed with an ink which contains dye so as to form an ink blend of a density which can be set by varying the mixing ratio. The ink blend thus formed is supplied to a recording head. The invention also provides an ink jet recording apparatus which permits inks of different compositions to be blended within the recording apparatus so a to enable selection of ink composition which is optimum for the image to be recorded or purpose of use.

摘要： A liquid jet head is provided with discharge ports for discharging liquid, liquid flow paths conductively connected with the discharge ports, air bubble generating areas for creating air bubbles in the liquid, and movable members arranged to face the air bubble generating areas, each having a free end in a position relatively near to the discharge port with respect to a fulcrum thereof. This movable member is inclined to position the free end of the movable member to release the air bubble generating area partly to the discharge port so as to enable the tangential line of the free end of the movable member on the side of the air bubble generating area or the extended line thereof to reach directly the discharge port formation area having the discharge port on the liquid flow path side before the creation of air bubble on the air bubble generating area, and with this position as reference, the movable member is displaced following the creation of air bubble on the air bubble generating area. With this arrangement, the liquid discharging efficiency and speed are significantly enhanced as compared with the conventional liquid jet head, and due to more stabilized discharge of droplets from the discharge ports, the quality of recorded images is improved.
