LIQUID DISCHARGING METHOD, LIQUID DISCHARGING HEAD, AND LIQUID DISCHARGING APPARATUS
摘要:
A liquid discharging method includes applying pressure to liquid and discharging the liquid from a liquid discharging head. The viscosity of the liquid ranges from 8 to 20 millipascal seconds. The liquid discharging head includes a nozzle that discharges the liquid, a pressure chamber that causes a pressure change in the liquid so as to discharge the liquid from the nozzle, and a liquid supplying section that is in communication with, and supplies the liquid to, the pressure chamber. The pattern of the pressure change in the liquid varies to selectively control the amount of the liquid discharged from the nozzle between a predetermined amount and another smaller amount. The diameter of the nozzle ranges from 15 μm to 40 μm. The flow-channel length of the nozzle is set at a value that is smaller than the flow-channel length of the liquid supplying section multiplied by 0.2.
