INK JET RECORDING HEAD AND INK JET RECORDER |
摘要 |
Ink stored in an ink tank (11) is filled in a pressure room (14) via a supply path (12) and a supply port (13). A piezo-actuator (15), when applied with a drive voltage by a drive voltage control unit (16), vibrates a diaphragm (17) which in turn changes the volume of the pressure room (14) to eject ink in the pressure room (14) from a nozzle (18) toward a form (2), the diameter of the nozzle (18) being set to within 20 to 40 mu m and the viscosity of the ink to within 2 to 6 mPa•s, thereby stably ejecting droplets of not larger than 25 mu m in diameter and providing a high-quality image. When a drive waveform voltage is corrected in accordance with an environmental temperature detected by a temperature detector (19) to set an ink viscosity to within 2 to 15 mPa•s, a high-quality image can be maintained.
