摘要： An ink jet printing apparatus and an ink jet printing method are provided which, when printing small ink droplets at high resolution, can make white lines caused by an “end dot deflection” less visually conspicuous. To that end, an ink jet print head used has a plurality of nozzle substrates H1100 so arranged that an overlapping region in which the printable areas of respective nozzle substrates partly overlap is formed. According to a print density to be achieved, each of the nozzles H1105 corresponding to the overlapping region is controlled for ejection/non-ejection of ink. With this method, it is possible to print as many dots as most match the intensity of the “end dot deflection” phenomenon that varies according to the print density. This enables a blank line to be filled with an appropriate number of dots at all times, regardless of the width of the blank line.

摘要： A liquid ejection head includes a liquid path; an ejection outlet forming member which constitutes a part of a wall of the liquid and which forms an ejection outlet for ejecting a droplet of liquid; a heat generating element, provided at a position opposing to the ejection outlet of the wall of the liquid flow path, for generating a bubble in the liquid by application of heat to the liquid; a restrictor portion, provided at a recessed portion of the ejection outlet, wherein the recessed portion is recessed from a plane in which the ejection outlet is formed, wherein the liquid forms a meniscus and is retained in the ejection outlet such that the restrictor portion is within the liquid, wherein an area So of an opening of the restrictor portion and a surface Sh of the heat generating element satisfy So≦Sh. According to this invention, a central portion of the meniscus opposed to the fine opening at the ejection outlet bulges, and the liquid is ejected in this state. Namely, very small amount of the liquid can be ejected, since not all of the liquid in the recess portion in the ejection outlet is ejected.

摘要： Two lines extending in the main scanning direction build a set of lines (L1, L2) each of which is formed by a plurality of dots. Assignment is alternately executed to preceding scanning and subsequent scanning so as to allow each of the lines (L1, L2) formed by a number of pixels (P1, P2, P4, P3, P5, P6, P8, P7, - - - ) to extend along a snake movement-like route. Thus, dots located adjacent to each other in the auxiliary scanning direction are not formed by same scanning, and a quantity of ink spreading on a recording medium without penetration of the ink through the latter can be reduced. Consequently, there few arises stripe and fluctuation in density, whereby an excellent quality of image having sharp edge portions can be obtained without any occurrence of a problem attributable to the presence of unfixed ink.

摘要翻译： 沿主扫描方向延伸的两条线构成一组由多个点形成的线（L1，L2）。 交替执行分配到先前的扫描和随后的扫描，以便允许由多个像素（P1，P2，P4，P3，P5，P6，P8，P7，...）形成的每条线（L1，L2） 沿着蛇运动的路线延伸。 因此，在辅助扫描方向上彼此相邻的点不是通过相同的扫描形成的，并且可以减少在没有通过后者的油墨渗透的记录介质上扩散的油墨量。 因此，几乎没有出现条纹和密度波动，由此可以获得具有尖锐边缘部分的优异的图像质量，而不会出现由于存在未定影油墨而引起的问题。

摘要： In a driving method of an ink-jet recording head, heat is generated by applying a drive signal to a heating element, and this heat is applied to ink to generate a bubble and discharge the ink through a discharge outlet. The drive signal comprises a first drive signal for storing foaming energy in the ink, and a second drive signal for generating a bubble in the ink. The second drive signal has a signal time shorter than the boundary foaming time at which foaming energy decreases in a case of performing foaming only by the second drive signal. The first drive signal is applied prior to the second drive signal in order to compensate for a decrease in foaming energy.

摘要： An image corresponding to a single sheet of recording paper is divided into three decomposed images 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.
