Patent attributes
The liquid droplet ejection apparatus includes a droplet ejection control device controlling droplet ejection whereby droplets of liquid are ejected from ejection heads (“heads”) towards an ejection receiving medium together with relative movement caused by a conveying device, and a row of dots is formed by droplets of the liquid landing on the ejection receiving medium wherein at least some of the dots overlap in a main scanning direction substantially perpendicular to the relative movement direction. When a position between nozzles at which a droplet ejection time difference between adjacent dots in the main scanning direction in one head differs from a droplet ejection time difference between other adjacent dots, referred to as a specific time difference nozzle pair position in a corresponding head, the head is positioned so that the specific time difference nozzle pair position differs in the main scanning direction between at least two of the heads.
