Abstract
A droplet discharge method is for discharging a liquid into a plurality of drawing regions partitioned on a substrate from a plurality of nozzles formed in a droplet discharge head while moving the droplet discharge head relative to the substrate. The droplet discharge method includes dividing the nozzles into a plurality of nozzle groups so that the nozzles in one of the nozzles groups face the same drawing region, correcting an amount of the liquid discharged from the nozzles so that an average value of an amount of the liquid discharged from the nozzles constituting the nozzle groups is substantially uniform among the nozzle groups, and discharging the liquid from the nozzles while the droplet discharge head is moved relative to the substrate.

A droplet discharge method for discharging a liquid into a plurality of drawing regions partitioned on a substrate from a plurality of nozzles formed in a droplet discharge head while moving the droplet discharge head relative to the substrate, the droplet discharge method comprising:
- dividing the nozzles into a plurality of nozzle groups so that the nozzles in one of the nozzles groups face the same drawing region;
- correcting an amount of the liquid discharged from the nozzles so that an average value of an amount of the liquid discharged from the nozzles constituting the nozzle groups is substantially uniform among the nozzle groups;
- and
- discharging the liquid from the nozzles while the droplet discharge head is moved relative to the substrate.
A droplet discharge device comprising:
- a droplet discharge head including a plurality of nozzles configured and arranged to discharge droplets of a liquid into a plurality of drawing regions partitioned on a substrate;
- a movement unit configured and arranged to move the droplet discharge head relative to the substrate;
- and
- a correction unit configured to divide the nozzles into a plurality of nozzle groups so that the nozzles in one of the nozzles groups face the same drawing region, and to correct an amount of the liquid discharged from the nozzles so that an average value of an amount of the liquid discharged from the nozzles constituting the nozzle groups is substantially uniform among the nozzle groups.
