摘要： Disclosed is a liquid emitting apparatus for emitting a liquid pressurized by a pressure generated by a pressure generating element is emitted as liquid droplets onto a support. A controller (68) controls an emission controller (63) so that the current value of the pulse current supplied to a heating resistor (42a) will have a current value difference within ±10% with respect to the current value of the pulse current supplied to a heating resistor (42b). By so doing, variations in the position of deposition of an ink droplet i emitted with variable emitting directions may be suppressed to enable printing to a high-quality image in which deterioration in the image quality variations ascribable to color time variations or white streaks is prohibited.

摘要： With a liquid discharge device, a maximum of N liquid droplets are discharged so as to land within each pixel region for forming a pixel corresponding to the pixel region, a target landing position is selected at random for each liquid droplet, from M liquid landing position candidates, forming an array in the direction of an array of nozzles, determined such that at least a part of the landing liquid droplet region corresponding to each landing position candidate is included within the pixel region, and the discharge direction of the liquid droplet is controlled such that the liquid droplet lands at the determined target landing position. The liquid discharge device having such a configuration has the advantage of preventing occurrence of streaks between dot columns in a printed image due to irregularities in an array of discharge portions.
