Liquid ejecting apparatus and liquid ejecting method
Abstract:
A liquid-ejecting-apparatus includes a nozzle that ejects liquid with a viscosity of 50 mPa·s or higher; a pressure-chamber communicating with the nozzle; a pressure-change-portion that changes a pressure of the liquid in the pressure-chamber; and a controller that controls the pressure-change-portion. The controller executes first control of decreasing the pressure of the liquid in the pressure-chamber, hence pulling a center portion of a meniscus toward the pressure-chamber, and forming a liquid-membrane with the liquid at an inner-wall-surface of the nozzle; and second control of, in a state in which the liquid-membrane is formed at the inner-wall-surface of the nozzle, increasing the pressure of the liquid in the pressure-chamber, hence inverting a shape of the center portion of the meniscus to a protruding shape protruding toward an opening of the nozzle and forming a liquid-column, and further, ejecting the liquid-column so as not to contact the liquid membrane.
