摘要： Since the large amount nozzle arrays are disposed at first columns and the small amount nozzle arrays are disposed at second columns on both sides of the shifting directions along the main scan direction, the deflection of the ink droplet caused by the first air flows is totally reduced.

摘要： A recording apparatus and a recording method for controlling and driving a recording head so that an image region formed by a first ink is located between alternate image regions formed by a second ink and that the ends of a region onto which a liquid is ejected are located with substantially the same interval as the end-to-end interval of the image region of the first ink, and are shifted to a plurality of locations. A plurality of timings of ejecting the liquid corresponding to the plurality of locations are stored in a memory device. Of these timings an optimum one is selected and input according to the result of recording and then the liquid is ejected at the optimum timing during recording. This ensures that even when plain paper is used as the recording medium, the liquid is ejected at the optimum timing at those positions in a boundary area between the ends of the image region of the first ink and the alternate image regions of the second ink which do not result in bleeding of the first and second inks. Hence, the adjustment of the ejection positions of the liquid and the first and second inks can easily be made.
摘要翻译：一种用于控制和驱动记录头的记录装置和记录方法，使得由第一墨水形成的图像区域位于由第二墨水形成的交替图像区域之间并且喷射有液体的区域的末端位于具有与第一墨水的图像区域的端到端间隔基本上相同的间隔，并且被移位到多个位置。将与多个位置对应的液体喷射的多个定时存储在存储装置中。在这些定时中，根据记录结果选择和输入最佳的定时，然后在记录期间以最佳定时喷射液体。这确保即使当使用普通纸作为记录介质时，在第一墨水的图像区域的端部与第二墨水的交替图像区域之间的边界区域中的那些位置处的最佳定时喷射液体，不会导致第一和第二种墨水渗色。因此，可以容易地进行液体和第一和第二墨水的排出位置的调整。

摘要： An ink-jet recording apparatus of the present invention is for eliminating the difference in printed results generated from an offset between the positions to which a main drop and satellite drop of ink are discharged respectively, and generated also from the difference in the ejecting order of processing liquid with respect to ink. The apparatus is constructed such that in a scanning operation in which a satellite ink drop Da2 is dropped onto a main ink drop Da1 ejected from the ink head section in a superimposed manner, the processing liquid Sa falls after the ink dot formed on the recording paper 16 is expanded to some extent, whereas in a scanning operation in which the satellite drop Db2 is dropped at a position offset from the position of the main drop Db1, the processing liquid Sb is first ejected, and those ink drops Db1 and Db2 are discharged thereafter, so as to suppress expansion of the ink dot, making thus a dot having substantially the same size with that formed in the above scanning case.
摘要翻译：本发明的喷墨记录装置用于消除从主墨滴和卫星墨滴分别排出的位置之间的偏移产生的打印结果的差异，也是从喷墨顺序的不同而产生的相对于油墨处理液体。该装置被构造成使得在卫星墨滴Da2以重叠的方式从墨头部分喷射的主墨滴Da1上落下的扫描操作中，处理液Sa落在记录纸上形成的墨点之后 16扩展到一定程度，而在从主液滴Db1的位置偏离的位置下降卫星滴Db2的扫描动作中，首先喷射处理液Sb，喷出墨滴Db1，Db2 此后，抑制墨点的膨胀，从而形成与上述扫描情况下形成的点大致相同的点。

摘要： An ink jet recording head is provided with one heat generating member in each of ink flow paths, and the discharge port thereof is arranged on the extended line extending in the normal direction from the center of the main surface of the heat generating member to the surface of the substrate. Then, on the surface of the substrate, non-bubbling area is provided on the center within the projected area having the discharge port projected thereon. Bubble brought to the boil by the heat generating member pushes out ink from the discharge port by the pressure exerted by the bubble, while being communicated with the outside. With the structure thus arranged, it is made possible to enhance the precision of discharge direction of the liquid droplet discharged from the discharge port.
