Abstract:
A method of measuring a wetting property of a nozzle plate in a droplet expelling device having a number of nozzles formed in the nozzle plate, and an actuator system for expelling a droplet of a liquid from each of the nozzles includes applying an amount of liquid onto a surface of the nozzle plate, capturing a digital image of the nozzle plate with the liquid applied thereon, and analyzing the digital image for determining the wetting property from a distribution of the liquid on the nozzle plate. The amount of liquid is applied onto the nozzle plate by expelling liquid through the nozzle.
