Abstract: Each of pixels (No. 1 to N) of recorded image is formed by a plurality of dots composed with ink droplets ejected from a plurality of different orifices (No. 1 to M) at individual different main-scannings (No. 1, 2, 3 and so on). With this recording process, the variation of ink ejection characteristics between a plurality of orifices in a recording head can be reduced in forming pixels.

Abstract: Record is made to a record sheet (2) while a recording head (1) having a predetermined number of discharge ports arranged thereon is obliquely moved relative to the record sheet (2) and the recorded regions (21,22) are sequentially crossed to record the entire image on the record sheet. The pixels on the vertical and horizontal lines of the record sheet (2) are recorded by the predetermined number of different discharge ports.

Abstract: Disclosed is a recording apparatus for performing recording using an ink-jet recording head (1) for discharging an ink from an array of a plurality of orifices, including a drive unit for driving the recording head (1) on the basis of a recording signal to cause a first orifice of the plurality of orifices to discharge an ink at a first timing, and to cause a second orifice to discharge an ink at a second timing, and a moving unit for moving the recording head (1) and a recording medium (2) relative to each other by an amount corresponding to a distance between the first and second orifices during a time interval between the first and second timings by the drive unit. There is also disclosed a recording method.

Abstract: An image corresponding to a single sheet of recording paper is divided into three decomposed images(1,2,3) each having the substantially same expansion as that of the image, and one of the decomposed images is recorded on the recording paper while a drum is rotated and the recording head is continuously moved at a distance corresponding to a width of the recording head. Subsequently, other decomposed images are successively recorded on the recording paper. Thus, recording of the respective decomposed image is performed at a predetermined time interval kept between two continuous recordings. The foregoing time interval can be used as a time required for ink permeation into the recording medium.

Abstract: It is an object to provide an ink-jet recording apparatus capable of always obtaining an image having a high quality without difficulty for a user by precisely detecting a cause which deteriorates image quality and by efficiently resolving the cause. The cause of the deterioration in image quality is detected on the basis of a difference S between image data G intended to be recorded and read data Y which is obtained by reading the image that is recorded on a recording medium (S = G - Y), thereby determining a processing method for resolving the cause. The determined processing method is executed and, thus, normal recording is always possible.
