Abstract

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.
