摘要： An ejection control device includes a memory for storing a correspondence table between gray-scale data items and ejection pattern data items, each gray-scale data item determining the number of droplets to be ejected to a corresponding pixel so as to express a desired gray-scale level of the pixel, each ejection pattern data item determining the ejection timing of droplets; and a converter for converting each gray-scale data item of the corresponding pixel to the corresponding ejection pattern data item by referring to the table. In the table, the setting of the ejecting position can be freely adjusted. In particular, an ejection pattern having ejection data bits discretely distributed for one pixel range can be easily achieved. Moreover, compliance with system changes can be achieved simply by rewriting the table.

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： A liquid discharge apparatus having heads with liquid dischargers including nozzles aligned in parallel in a row. Each liquid discharger has a main controlling unit for discharging ink droplets from the nozzles of the liquid discharger, a secondary controlling unit for controlling the discharge of a droplet so that the droplet is discharged along at least one trajectory different from the trajectories of the droplets discharged from a liquid discharger controlled by the main controlling unit, and a secondary-control executing unit for individually setting whether or not the secondary controlling unit for each liquid discharger is operated. The liquid dischargers controlled by the secondary controlling unit discharge ink droplets along different trajectories compared to the ink droplets discharged by other liquid dischargers.

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.
