Patent ID: 7045012

Claim:
A liquid jetting apparatus for jetting a liquid to be applied to a substrate, comprising: a first droplet jet head disposed at a first distance from a center of rotation of the substrate, said first droplet jet head having a first nozzle train positioned at a first angular orientation relative to a radial direction of the substrate; a second droplet jet head disposed at a second distance from said center of rotation of the substrate, said second droplet jet head having a second nozzle train positioned at a second angular orientation relative to said radial direction of the substrate; and a third droplet jet head disposed at a third distance from said center of rotation of the substrate, said third droplet jet head having a third nozzle train positioned at a third angular orientation relative to said radial direction of the substrate; wherein said second distance is greater than said first distance and said third distance is greater than said second distance; and wherein said first angular orientation is different from said second angular orientation and said third angular orientation is different from said second angular orientation.
