摘要： Characteristics of a droplet ejection apparatus are change depending on the shape or cone angle of the main ink ejection chamber of the apparatus, or on the diameter of the ejection aperture of main ink ejection chamber. Accordingly, operation of the droplet ejection apparatus varies with the shape, angle, or diameter of main ink ejection chamber. The shape of the aperture according to the present invention is circular or regular polygonal so that surface waves are synthesized at the central portion of the ejection aperture. Moreover, the cone angle of the main chamber is set to 65° or less from the plane vertical to the droplet ejecting direction and the diameter of the ejection aperture is set to a value 1.25 times or more larger than a desired droplet diameter.

摘要： A drive method and a drive of an ink-jet recording head which is capable of improving recording speed widely, and which is capable of materializing high quality recording without extending recording time even though the number of gradations increase, are provided. One-printing period T is divided into a plurality of segment T1, T2. The method and device cause plural kinds of drive-voltage-waveform SD1 to SD6 to be generated in accordance with size of an ink-drop in every respective segment T1, T2. The method and device select arbitrary drive-voltage-waveforms from among the plural kinds of drive-voltage-waveforms SD1 to SD6 supplied in every respective segment T1, T2 to supply to a vibration generator in every respective segment T1, T2. Thus it becomes possible to obtain a plurality of gradations during one-printing period T. It is capable of obtaining high quality printing image while improving recording speed widely. Further, printing time is not extended even though the number of gradations increase.
