Abstract:
1. A method of discharging droplets comprising: discharging a liquid material from a plurality of droplet discharge heads forming a discharge head assembly and causing the discharge head assembly and a substrate as a landing target for the liquid material to move relative to each other to thereby deposit the liquid material on the substrate; feeding a to-be-treated substrate and removing a treated substrate to and from a droplet discharge apparatus provided with the discharge head assembly; performing a weight measurement discharge from one of the droplet discharge heads included in the discharge head assembly substantially concurrently with the feeding and removing; performing a dummy discharge from the rest of the droplet discharge heads included in the discharge head assembly concurrently with the performing of the weight measurement discharge from the one of the droplet discharge heads; and measuring the weight of the liquid material discharged in the weight measurement discharge.
