摘要： PROBLEM TO BE SOLVED: To prevent a striking interference of liquid droplets ejected to overlap each other on a recording medium. SOLUTION: Nozzles are arranged so that at least a part of dots formed by striking the liquid droplets including organic pigment fine particles on the recording medium overlaps in a main scanning direction. First and second nozzles which strike the dots adjacent to each other in the main scanning direction on the recording medium, and a third nozzle adjacent in a sub scanning direction to the first nozzle are arranged so that a sub scanning directional distance between the first and second nozzles becomes at least an integral multiple of not smaller than 2 of a sub scanning directional distance between the first and third nozzles. Thus a striking time difference between the ejected liquid droplet from the first nozzle and the ejected liquid droplet from the second nozzle is made long, so that the striking interference of both ejected to overlap each other is prevented. At the same time, the nozzles are arranged so that a distance in the main scanning direction between the first and third nozzles becomes at least a distance of not smaller than the maximum dot diameter of the liquid droplet ejected to the recording medium from the first nozzle.

摘要翻译：要解决的问题：为了防止喷射的液滴在记录介质上彼此重叠的明显干扰。解决方案：排列喷嘴，使得通过将包括有机颜料微粒在内的液滴撞击在记录介质上的至少一部分点在主扫描方向上重叠。在记录介质上沿主扫描方向相邻的点和与副扫描方向相邻的第三喷嘴相对于第一喷嘴的第一和第二喷嘴被布置成使得第一和第二喷嘴之间的副扫描方向距离喷嘴成为第一和第三喷嘴之间的副扫描方向距离的至少不小于2的整数倍。因此，来自第一喷嘴的喷出的液滴和来自第二喷嘴的喷射的液滴之间的显着的时间差被制造得很长，从而防止了两个喷射的撞击干扰彼此重叠。同时，喷嘴被布置成使得第一和第三喷嘴之间的主扫描方向上的距离至少为不小于从第一喷嘴喷射到记录介质的液滴的最大点直径的距离。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an image formation apparatus which can prevent image deformation caused by overlapped dots with short recording time. SOLUTION: An organic pigment solvent dissolved in an aqueous solvent is caused to pass through a channel as a laminar flow. In the laminar flow process, droplets including organic pigment fine particles generated in the process of changing the hydrogen-ion exponent of the solution are discharged, thereby forming a first dot 102 and a second dot 112 so that they are overlapped with each other. First, an ink droplet 100 having a diameter D1a which forms the first dot 102 is discharged. When a predetermined time is elapsed, the ink droplet 100 is permeated into the recording paper, and the diameter on the recording paper surface becomes D1b. When the ink droplet 110 which forms the second dot 112 is discharged in this state, the ink droplet 100 and the ink droplet 110 are not mixed with each other. Moreover, mixture of the inks does not occur also in the recording paper since ink permeated into the recording paper is retained in an image receiving layer in the recording paper.

摘要： PROBLEM TO BE SOLVED: To enable to surely recover a nozzle, and to suppress the amount of consumption of ink caused by recovering operation. SOLUTION: A solvent for an organic pigment dissolved in an aqueous solvent is passed through a flow path as a laminar flow, and liquid droplets containing organic pigment finely divided particles formed in a process in which the hydrogen ion index of a solution is changed in the laminar flow process are hit. By the nozzle in a printing head, hitting the liquid droplets is performed at a droplet hitting point 102 at a timing Ta in the previous image 100, and hitting the liquid droplets is performed at a droplet hitting point 112 at a timing Tc in the next image 110. When the sum of a non-working time T1 from Ta to the present time Tb and a non-working predetermined time T2 from Tb to Tc exceeds a preliminary delivering reference time, a preliminary delivering is performed. As not only the past non-working time but also the non-working predetermined time are calculated, and whether the preliminary delivering is performed or not is judged by summing them up, abnormality of delivering and generation of non-delivering can be prevented in the midway of imaging. Two preliminary delivering reference times are provided, and one is a time by generating abnormality of delivering and the other is a time by generation of non-delivering.
