Liquid ejecting method, liquid ejecting head, and liquid ejecting apparatus

摘要

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 20 mPa·s, wherein 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, and wherein the opening area of the nozzles on the side in which the liquid is ejected is 1/10 or less of the opening area of the opening of the supply unit on the pressure chamber side.

1. A liquid ejecting method, comprising:
ejecting a liquid from a liquid ejecting head, wherein the viscosity of the liquid is in a range from 6 mPa·s to 20 mPa·s, wherein the liquid ejecting head includes:
a nozzle plate with a nozzle which ejects the liquid;a pressure chamber which applies a pressure variation to the liquid in order to eject the liquid from the nozzle;a supply unit which communicates with the pressure chamber and supplies the liquid to the pressure chamber from a liquid storage chamber; anda vibration plate disposed opposite from the nozzle plate, the vibration plate including a laminate of a support substrate and an elastic member, the elastic member forming a portion of the pressure chamber, the supply unit, and the liquid storage chamber,wherein a length of the nozzle is in a range from 40 μm to 100 μm and a diameter of the nozzle is more than 10 μm,an opening area of an opening of the nozzle on the side in which the liquid is ejected is 1/20 or more of an opening area of an opening of the supply unit, anda cross-sectional area of the pressure chamber in a direction transverse to a flow of the liquid from the supply unit is less than three times a cross-sectional area of the supply unit in the direction transverse to the flow of the liquid.
