Problems solved by technology

[0005] On the contrary, the tip of a line printer does not move, so once a field has been recorded, it cannot be re-recorded by overwriting the dot
Therefore, the line printer has a problem that the characteristics of each liquid discharger vary in the direction in which the liquid dischargers are arranged, resulting in uneven stripes

no. 1 Embodiment 1

[0153] The pixel formation process shown in FIG. 13 is the same as that in FIG. 12 , so it is omitted here. Like the first embodiment, the second embodiment also employs the first discharge control unit to control the discharge of ink droplets from at least two adjacent liquid dischargers so as to constitute pixel rows or pixels.

[0154] (second emission control unit)

[0155] In this embodiment, the head 11 has the above-mentioned discharge direction changing unit or the main control unit and the second control unit, the reference direction setting unit and the discharge angle setting unit, and the head 11 is used by applying the first control unit as described below. Two discharge control units to control the discharge of ink droplets.

[0156] The second discharge control unit selects a landing position (or more precisely, a target position) in a predetermined direction in the pixel area for each ink droplet discharged from the liquid discharger. The landing position is ...

Abstract

A liquid discharge apparatus having heads (11) with liquid dischargers including nozzles (18) aligned in parallel in a row. Each liquid discharger has a main controlling unit for discharging ink droplets from the nozzles (18) 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.

Description

technical field [0001] The present invention relates to a liquid discharge device comprising a plurality of heads having liquid dischargers including nozzles arranged in parallel; A method of draining liquids with multiple ports. More specifically, the present invention relates to a technique for individually setting droplet trajectories for each liquid discharger and enabling each liquid discharger to discharge droplets in an appropriate direction. Background technique [0002] One type of known liquid ejector is an inkjet printer. Known inkjet printers are of two types: 1) serial printers, in which the tip moves in the width direction of the recording medium and discharges droplets onto the recording medium as the recording medium moves in the feed direction; 2) line type A printer in which line headers are arranged across the width of a recording medium, and only the recording medium moves in a direction perpendicular to the width direction of the recording medium when ...
