US Patent 7147296 Ejection control of quality-enhancing ink

This invention is a printing method of forming dots on a print medium by ejecting a colored ink and a quality-enhancing ink. This method generates dot data representing a state of dot formation of the color dot and the transparent dot at each pixel based on the color dot recording rate table and the transparent dot recording rate table. The transparent dot recording rate table is configured to require a less process load for generation of the dot data than the color dot recording rate table.
