    摘要： For both reducing the ligament length and satellite droplet problems associated with producing high velocity ink droplets from an ink jet head printing at relatively high ink jet head-transport speeds, the ink jet head is driven by composite waveform including independent and successive first, second, and third electrical pulses (332,334,336), each having an exponential leading edge and a step-like trailing edge, the pulses having amplitudes, pulse widths (T 1 ,T 3 ,T 5 ), and dead times (T 2 ,T 4 ) between pulses, for causing the ink jet head to eject three successive ink droplets, each of increased velocity (V,, V 2 , V 3 ) relative to the preceding droplet, for causing the droplets to merge in flight to form a single or ultimate droplet (344) having a predetermined velocity (V4).

    摘要： A recording head is provided with a pressure chamber communicated with a nozzle orifice. A pressure generating element generates pressure fluctuation in ink contained in the pressure chamber. A drive signal generator generates a drive signal for driving the pressure generating element such that a main ink droplet and a satellite ink droplet accompanied with the main ink droplet are ejected to form an ink dot on a recording medium. The main ink droplet has a first volume, and the satellite ink droplet has a second volume which is larger than the first volume. Altematively, the main ink droplet is ejected with a first speed, and the satellite ink droplet is ejected a second speed which is faster than the first speed.

    摘要： An imaging apparatus capable of inhibiting inadvertent ejection of a satellite ink droplet (22) and method of assembling same. The imaging apparatus comprises a print head transducer (160) including a pair of sidewalls (180/190) defining a chamber (170) therebetween, the chamber having the ink body (200) disposed therein. The transducer is in fluid communication with the ink body for inducing a first pressure wave (300) in the ink body in order to eject an ink droplet (20). A waveform generator (80) is connected to the transducer for supplying voltage waveforms (290/330) to the transducer, so that the transducer induces pressure waves in the ink body. However, the first pressure wave has a reflected portion (310) formed by the first pressure wave reflecting from the sidewalls. The reflected portion is sufficient to otherwise inadvertently eject unintended satellite ink droplets. Thus, a sensor (320) is in fluid communication with the ink body for sensing the reflected portion and is connected to the transducer for inducing a second pressure (360) wave in the ink body. The second pressure wave has an amplitude and phase damping the reflected portion of the first pressure wave in order to inhibit inadvertent ejection of satellite ink droplets.

    摘要： A density difference correction signal (718) is generated for correcting a density difference upon forward path printing and backward path printing by density difference correction signal generating apparatus (102B) to store the generated density difference correction signal (718) in an unevenness correction RAM (717). A predetermined correction line in a HS table memory (511) is selected depending upon the density difference correction signal (718). By the selected correction line, the density correction of the image data (704) of forward path printing and backward path printing is performed to output the image data (706).
