Abstract:
1. A droplet information measuring method, comprising: disposing a first droplet and a second droplet separated from the first droplet at a first distance on a measuring apparatus, the first distance being the distance between the centers of the first droplet and the second droplet; determining a first drying time by measuring a drying time at which the first droplet and the second droplet evaporate from the measuring apparatus; disposing a third droplet and a fourth droplet separated from the third droplet at a second distance on the measuring apparatus, the second distance being the distance between the centers of the third droplet and the fourth droplet; determining a second drying time by measuring a drying time at which the third droplet and the fourth droplet evaporate from the measuring apparatus; comparing the first distance to the second distance and comparing the first drying time to the second drying time; and determining a drying time of the first droplet in a condition in that evaporation of the first droplet is not affected by vapor evaporated from the second droplet, when the first distance is different from the second distance, and when the first drying time is equal to the second drying time.
