    摘要: This ink jet recording apparatus makes it possible to reduce the requisite number of times that preliminary ejection is performed for the purpose of ejection recovery through suction, which must be effected to such a degree as to make color mixing on the recording paper sufficiently inconspicuous. With a plurality of recording heads using inks of different lightnesses, ejection recovery is performed successively on the recording heads in accordance with the descending order of ink lightness. In addition, the number of preliminary ejections after ejection recovery to be performed on the next recording head is also controlled, thereby attaining a still greater effect. In a method aspect, the present invention includes an initial discharge step for discharging ink from a recording head, interrupting the discharge of ink for an appropriate period set in accordance with the ink lightness, and discharging ink again from the discharge ports of the recording head after the interruption.

    摘要: A recording scan is performed through a relative reciprocation of color recording heads on a recording material. The recording heads can record with higher recording density than that of input image date. A plurality of pixels (2.times.2)are formed for each pixel of input image data. A mixed color image is recorded by multiple scans of the recording heads, in such a manner that pixels thereof (2.times.2) are not subjected to superposition of ink of two colors or more during a scan of the recording heads. Thus, it is possible to prevent an occurrence of variations in mixed color, and to record a high quality color image without increasing a recording time. Further, an amount of ink of one color may be reduced when recording a second one of the scans.

    摘要: A recording head having a plurality of ink discharge element lines arranged thereon is moved in a direction different from the direction of arrangement of the ink discharge elements to conduct a main scan, and at the end of the main scan, a recording medium is moved by a predetermined width in a direction different from the main scan direction to record an image. A record area of the recording head is divided into a plurality (n) of areas and each unit image area on the recording medium is main scanned n times by using the n divided areas of the recording head and thinned images with a print factor of 1/n are sequentially recorded to complete the record of the unit image area. The print factor for the pixels in the boundary area of adjacent unit image areas is lower than the print factor to the entire unit image area in at least one of the n main scans. Thus, the number of pixels recorded by the same main scan in the boundary area is increased. A high quality image without a joint stripe is attained even for a recording medium having a relatively high ink absorption speed.
