    摘要： A liquid discharge apparatus (1) includes a liquid discharge head (34a, 34b) including a plurality of nozzles (104) to discharge liquid droplets, a plurality of individual liquid chambers (106) communicating with the plurality of nozzles (104), and a plurality of pressure generators (112) to generate a pressure that pressurizes liquid in the plurality of individual liquid chambers, and a head drive controller (509) to output, to the plurality of pressure generators (112), a drive waveform including one pulse or two or more pulses selected according to a droplet size. In a case that the drive waveform includes the two or more pulses, the drive waveform includes a final pulse at an end of the two or more pulses. The final pulse includes a first expansion waveform element, a first contraction waveform element, a second expansion waveform element, a second contraction waveform element, and a third expansion waveform element for expanding the plurality of individual liquid chambers, the third expansion waveform element being subsequent to the second contraction waveform element. A time period from a start of the first contraction waveform element to a start of the second expansion waveform element is less than 0.5 Tc. A time period from the start of the first contraction waveform element to a start of the second contraction waveform element is within a range from 0.5 Tc to 0.6 Tc.

    摘要： An ink-jet recording method is characterized in that an ink drop of an ink of 5 to 20 mPa·s is ejected toward a recording medium from the nozzle of an ink-jet head to form a main drop and satellites from the ejected ink drop and a condition that the main drop speed at a position 1 mm away from the nozzle surface is 5 m/s or more and the distance from the position of the main drop 1 mm away from the nozzle surface to the rearmost satellite is 500 μm or less is set by adjusting the drive voltage of the head to thus record an image on the recording medium. An ink for ink-jet recording used for the above ink-jet recording method is also disclosed.

    摘要： An apparatus for ejecting very small droplets according to the present invention comprises a first ink ejector (100) and a second ink ejector (200). The first ink ejector is controlled to eject a main droplet (12) and a satellite droplet (13) in accordance with one ink ejection signal such that the main droplet collides with an ink droplet (14) ejected from the second ink ejector. A trajectory of a united droplet (15), formed by the collision of both droplets, is different from a trajectory of the main droplet, and the united droplet flies toward an ink catcher (30). Only the satellite droplet having very small volume lands on a paper.

    摘要： An inkjet printing apparatus and method of operating an inkjet printhead provides an inkjet orifice of the printhead that is located within a predetermined spacing of less than 1000 micrometers, and more preferably in a range of 50 to less than 500 micrometers for printing high resolution images. Electrical drive signals are provided to the printhead, the drive signals being adapted to enable the printhead to generate a droplet. In response to the drive signals, a free droplet is formed between the orifice and a receiver member and deposits a droplet upon the receiver member substantially without presence of any satellites.

    摘要： For improving stable ink droplet ejection at high speed, an ink jet recording apparatus comprises an ink jet head having one or more ink jet units each including a nozzle (11) for ejecting ink droplets; an ink chamber (5) in communication with said nozzle on the one hand and ink supply means (6, 7) on the other hand; an elastic diaphragm (8) forming at least a portion of a wall of said ink chamber; an actuator (8, 10) responsive to drive signals so as to selectively deform said diaphragm and alter the volume of said ink chamber; and abutment means (91, 15) arranged outside of said ink chamber opposing said diaphragm with a gap being formed between said diaphragm and said abutment means when the former is not deformed. The recording apparatus further comprises drive means including an ejection signal generator for applying a first drive signal to said actuator to eject an ink droplet from said nozzle; a timer responsive to said ejection signal generator for generating a timing signal at a predetermined interval after receiving the first drive signal; and a complementary signal generator responsive to said timing signal for applying a second drive signal to said actuator to displace said diaphragm into contact with said abutment means.
