Abstract:
Provided is a liquid ejecting method, including ejecting a liquid from a liquid ejecting head, wherein: the viscosity of the liquid is in a range from 6 mPa·s to 15 mPa·s, the liquid ejecting head includes: nozzles which eject the liquid; a pressure chamber which applies a pressure variation to the liquid in order to eject the liquid from the nozzles; and a supply unit which communicates with the pressure chamber and supplies the liquid to the pressure chamber, the volume of the supply unit is more than ⅕ of the volume of the pressure chamber and is less than ½ of the volume of the pressure chamber, and the channel length of the pressure chamber is equal to or more than the channel length of the supply unit and is equal to or less than twice of the channel length of the supply unit.
