摘要： The present invention relates to a method of operating a droplet ejection device comprising an ejection unit arranged to eject droplets of a liquid and comprising a nozzle formed in a nozzle face, a liquid duct connected to the nozzle, and an electromechanical transducer arranged to create an acoustic pressure wave in the liquid in the duct, wherein a step of detecting visco-elastic liquid in the duct by analyzing in the frequency domain a signal S, of acoustic pressure fluctuations decaying in the duct after the ejection of a droplet obtained from the transducer. The invention further relates to a droplet ejection device, a printing system and a software product suited for or capable of performing said method.
