US Patent 7380907 Liquid ejection apparatus and liquid ejection method

The number of liquid droplets ejected toward a region outside a medium, which becomes a necessary evil when forming dots all the way to the edges of the medium by ejecting liquid droplets, can be decreased without greatly impairing the formation of dots at the edges. A liquid ejection apparatus for ejecting a liquid, includes: a liquid ejection section for ejecting liquid droplets toward a medium in order to form dots on the medium; wherein the liquid ejection section ejects, toward a vicinity of an edge of the medium, the liquid droplets of a number that has been thinned out by a suitable number; and wherein at least a portion of the liquid droplets ejected after thinning does not land on the medium.
