20090096825 | Ejection Device and Ejection Method with Uneven Liquid Ejection Control Effect - A liquid ejection device of the invention is constructed to eject a liquid to an ejection object. The liquid ejection device has a dot data generator configured to generate dot data from given image data, where the dot data represents a dot creation state in each pixel set on the ejection object. The liquid ejection device also has a liquid ejector equipped with a nozzle array including multiple nozzles aligned in a specific direction substantially perpendicular to a scanning direction. The liquid ejector makes multiple scans of the nozzle array in the scanning direction in a common printing area according to the generated dot data and ejects the liquid to the ejection object to create dots. The dot data generator has a specific print mode that generates corrective dot data by skipping a virtual dot array created by one scan from a group of dot arrays to be created by the multiple scans of the nozzle array, in order to prevent a potential contact with a dot array to be created by another scan. This arrangement desirably prevents unevenness of liquid ejection caused by a meandering scan of at least either the liquid ejector or the ejection object. | 04-16-2009 |
