Abstract

The present invention discloses a liquid ejecting device that ejects a maximum of N liquid droplets so as to land on each pixel area to form a pixel corresponding to the pixel area, from among M liquid candidate drop positions that form an array along the nozzle arrangement direction Randomly select the target drop position of each droplet, determine the target drop position so that at least a part of the drop drop area corresponding to each candidate drop position is included in the pixel area, and control the ejection direction of the droplet so that the droplet falls at the determined target drop position. A liquid ejecting device having such a structure has an advantage of preventing streaks from being generated between dot matrixes of a printed image due to irregularities in the arrangement of the ejecting portions.

Description

technical field

[0001] The present invention relates to a liquid ejecting device and a liquid ejecting method for ejecting liquid droplets, and more particularly, to a liquid ejecting device and a liquid ejecting method capable of providing improved image quality. Background technique

[0002] In general, a conventional inkjet printer is a liquid ejecting device including a head in which ink ejecting portions each having a nozzle are arranged in a line. With this type of inkjet printer, a small liquid droplet (ink droplet) is ejected from each ink ejection portion of the head onto a recording medium such as printing paper set facing the end face of the nozzle to form a conventional circular dot on the recording medium , so that an image pixel is formed from a single point or multiple points. Also, the image pixels are two-dimensionally arranged to form images or characters.

[0003] On the other hand, for an inkjet printer, liquid droplets with some irregularities are ejec...
