Patent ID: 8031367

Claim:
A liquid ejection device constructed to eject a liquid to an ejection object, the liquid ejection device comprising: an ejection head structured to have a nozzle array including multiple nozzles aligned in a specific direction crossing a scanning direction; a dot data generator configured to generate dot data from given data, where the dot data represents a dot creation state corresponding to droplets of the liquid to be ejected in each unit set on the ejection object; and a liquid ejector configured to make multiple scans of the ejection head with the nozzle array in the scanning direction in a common printing area according to the generated dot data and eject droplets of the liquid to the ejection object to create dots, wherein the dot data generator has a specific print mode that generates corrective dot data by skipping a virtual dot array created by at least 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.
