摘要： A liquid jet recording method for recording on a recording material with liquid droplets discharged through plural scanning nozzles arranged in a width measured in a direction of main scan. The recording method includes a first main scan by relative movement between the nozzles and the recording material, in which pixels are recorded with numbers of droplets through a nozzle, the numbers of droplets corresponding to respective tone signals. The method also includes a sub-scan by relative movement between the nozzles and the recording material in a direction crossing with a movement direction of the first main scan. The method further includes a second main scan in which the pixels are recorded with numbers of droplets through a different nozzle, the latter numbers of droplets corresponding to tone level signals. The sub-scan and second main scan steps are repeated to record a tone image by discharging plural droplets for a pixel.

摘要： A fluid ejection head comprises a heater disposed in a fluid path. A bubble is generated by supplying electric power to the heater, and ink is ejected in a direction substantially parallel to a face of the heater. The fluid path is shaped to have a first part with a constant-sectional area adjacent to an ejection orifice a second part located behind the first part and containing the heater. The cross-sectional area of the second part increases by twice as large as the cross-sectional area of the ejection orifice, a length (A) between an end of the first part of the fluid path and a top end of the heater is greater than or equal to half of the height Ph of the ejection orifice, and a shortest gap between the ejection orifice and the heater is less than or equal to a sum of a half of the height Ph of the ejection orifice and a length (L) of the first part of the fluid path.

摘要： A line of ink nozzles in an ink-jet recording head is inclined obliquely from a scanning line, and one pixel is formed by a plurality of ink droplets discharged from different ink nozzles. Thus, a high halftone recording image without stripes (banding) due to a variation of a discharged ink volume or unevenness of recording image density, can be obtained. Moreover, since there is a large degree of freedom in designing an amount of the discharged ink volume, high packing density of ink nozzles can be easily achieved.

摘要翻译： 喷墨记录头中的一排墨嘴​​从扫描线倾斜倾斜，一个像素由从不同墨喷嘴排出的多个墨滴形成。 因此，可以获得由于排出的墨水量的变化或记录图像浓度的不均匀性而产生无条纹（带状）的高的半色调记录图像。 此外，由于在设计排出的油墨量的量方面存在很大的自由度，因此可以容易地实现油墨喷嘴的高堆积密度。

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： 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.
