Abstract:
1. A liquid ejection apparatus for ejecting a liquid, comprising: a liquid ejection section for ejecting liquid droplets toward a medium in order to form dots on said medium; wherein said liquid ejection section ejects, toward a vicinity of an edge of said medium, said liquid droplets of a number that has been thinned out by a suitable number; wherein at least a portion of the liquid droplets ejected after thinning does not land on said medium; wherein an image formed on said medium is constituted by raster lines that are arranged in parallel to one another at a predetermined interval in a direction intersecting the direction of said raster lines, each of said raster lines being made of a multitude of dots arranged on a straight line; wherein the liquid droplets are thinned out by a predetermined thin-out number from an edge of said raster line; and wherein said thin-out number of the liquid droplets is changed in the direction intersecting the direction of said raster lines based on a predetermined change pattern, and said thin-out number is periodically changed in the direction intersecting the direction of said raster lines.
