摘要： An ink is ejected at the same timing from ejection orifices in a number corresponding to an ink quantity 7% or less of an ink quantity ejected from all the ejection enabled ejection orifices of a plurality of ejection orifices of a recording head, and the ink ejection period from all the ejection enabled ejection orifices is set to be 70% or more of the driving period. Since the quantity of an ink ejected per unit time is minimized, and the negative pressure level generated in a common ink chamber can be set to be closest to normal pressure, the amplitude of a refill oscillation is minimized to stabilize ejection, and the driving frequency can be further increased.
摘要翻译：在与喷墨孔相同的时刻，墨水以对应于从记录头的多个喷射口的所有喷射口喷出口喷出的墨量的7％以下的墨量喷射，喷墨所有喷射启动喷射口的时间段被设定为驾驶时间的70％以上。由于每单位时间喷射的墨量最小化，并且可以将普通墨水室中产生的负压水平设定为最接近正常压力，因此使再充电振动的振幅最小化以稳定喷射，驱动频率可以进一步增加。

摘要： In the case of printing in three-value level utilizing two kinds of inks mutually different densities for one color (higher and lower density inks), it is assumed that a reflection density of a region having a predetermined area when solid print is performed only by the lower density ink, and that when solid print is performed only by the higher density ink are expressed ODt and ODn, respectively. Since the granular appearance of the ink dots is expressed in terms of reflection density of one dot, the granular appearance of a lower density ink dot at a portion of image formed only by the lower density ink dots and the granular appearance of a higher density ink dot at a portion of image formed by the higher and lower density ink dots are expressed in terms of values of ODt and (ODn-ODt) divided by the number of pixels included in the above region, respectively. Accordingly, by making the reflection density ODt to be approximately one half of the reflection density ODn, the granular appearance produced by the lower density ink dot at the highlighted portion and the granular appearance produced by the higher density ink dot at the portion where the higher density ink dots scattered in the lower density ink dots can be made substantially equal to each other. For this purpose, it is preferable that a dye concentration of the lower density ink is to be about one fourth of that of the higher density ink.
