摘要： PROBLEM TO BE SOLVED: To make poor ejection inconspicuous even if a partial liquid ejection part causes a defect such as nonejection.
SOLUTION: The ejection direction of a droplet, which is ejected from each liquid ejection part, can be changed into a plurality of directions. Control is performed so that a pixel can be formed by ejecting the droplets in the respective different directions from at least the two different liquid ejection parts which are positioned in the vicinity of each other. Any one droplet arrival target position is determined from among a plurality of droplet arrival target positions in the arrival of the droplet in one pixel area, and the droplet is made to reach the determined droplet arrival target position, Thus, the control is performed so that the droplet arrival positions can be made different from one another each time the droplet is ejected. Additionally, when N droplets reach one pixel area so as to form one pixel, the control is performed so that the N droplets per cycle can be ejected from each liquid ejection part by sending out an ejection signal for the ejection of the N droplets per cycle to at least the two different liquid ejection parts positioned in the vicinity of each other, and any one droplet arrival position for each of the N droplets per cycle is determined from among the M different droplet arrival positions.

摘要翻译：要解决的问题：即使部分液体喷射部分导致诸如不注意的缺陷，也使不良喷射不显眼。解决方案：从每个液体喷射部喷出的液滴的喷射方向可以改变为多个方向。执行控制，使得可以通过从位于彼此附近的至少两个不同的液体喷射部分在各个不同的方向上喷射液滴来形成像素。在液滴到达一个像素区域中的多个液滴到达目标位置中确定任何一个液滴到达目标位置，并使液滴达到确定的液滴到达目标位置。因此，执行控制使得每次液滴喷射时，液滴到达位置可以彼此不同。另外，当N个液滴到达一个像素区域以形成一个像素时，执行控制，使得每个循环的N个液滴可以从每个液体喷射部分喷射出来，每个循环每次喷出N个液滴至少位于彼此附近的两个不同的液体喷射部件，并且从M个不同的液滴到达位置中确定每个循环中的每个N个液滴的任何一个液滴到达位置。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To control unevenness of density resulting from variation in characteristics at a liquid ejecting section without lowering the print speed and without increasing the memory. SOLUTION: In the density control method of a liquid ejector comprising a head juxtaposed with a plurality of liquid ejecting sections each having a nozzle, forming a dot by ejecting a liquid drop from the nozzle at the liquid ejecting section onto an object and capable of representing a halftone by dot arrangement, a density measurement pattern of a constant density is formed for all pixel strings in the main scanning direction, its density is read out, and then the density information of each pixel string and the relation between the number of ejected liquid drops and the density are determined. Upon receiving an ejection instruction signal, the number of liquid drops being ejected actually from the liquid ejecting section is differentiated from pixel string to pixel string based on the density information of that pixel string and the relation between the number of ejected liquid drops and the density thus controlling the density of a pixel string corresponding that ejection instruction signal.

摘要： PROBLEM TO BE SOLVED: To reduce stripe nonuniformity even when there are variations in discharge characteristics for each liquid discharger by performing correction depending on the discharge characteristics for each liquid discharger. SOLUTION: A liquid discharge apparatus is provided with a head 11 with a plurality of liquid dischargers having nozzles (dischargers A, B and the like) aligned in parallel in a specific direction. Each liquid discharger has a main controlling unit for controlling the discharge of droplets so that the ink droplets are discharged from the nozzles of the liquid discharger, a secondary controlling unit for controlling the discharge of droplets so that the droplets are discharged along at least one trajectory different from the trajectories of the droplets discharged from a liquid discharger controlled by the main controlling unit, and a secondary control-executing unit for individually setting whether or not the secondary controlling unit for each liquid discharger is operated. The liquid dischargers A and B controlled by the secondary controlling unit discharge ink droplets along different trajectories (the discharger A in the direction of the third from left, and the discharger B in the direction of the sixth from left) from the trajectory (fourth from left) of the ink droplets discharged by other liquid dischargers.
