    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 plurality of recording heads capable of ejecting inks of different colors is reciprocated relative to a recording material to print ink dots on the recording material while effecting main scanning in the forward and the backward pass thereof. A plurality of thinning patterns produced by preparing m.times.n unit picture element groups and arraying these unit groups in such a manner that the groups avoid mutually adjoining and assume a mutually complementary relation is used to effect a plurality of rounds of main scanning in the forward and the backward pass over an area which can be printed by one round of main scanning, record a thinned image, and complete the recording of an image. The array of picture element groups in the thinning patterns is determined so that the groups may mutually adjoin relative to the direction of main scanning.

    摘要: In a color ink jet recording system for performing color image recording on a recording medium using a plurality of recording heads and different color inks, the thinning ratio for at least one (e.g., black K) of the recording heads is set to be different from the thinning ratio for the remaining recording heads (e.g., cyan C, and the like). The total implantation quantity of the black ink can be twice the normal quantity without increasing the number of times of scan operations, and without causing boundary blur, and the print density of black can be increased.

    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.
