Title:
LIQUID DROPLET DISCHARGING DEVICE AND LIQUID DROPLET DISCHARGING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/264242
Kind Code:
A1
Abstract:
Provided are a liquid droplet discharging device and a liquid droplet discharging method with which scattering of liquid droplets of a preliminary discharge can be effectively suppressed. The liquid droplet discharging device comprises: a liquid droplet discharging unit provided with a nozzle for discharging a liquid droplet having volatility; and a control means that controls a liquid droplet discharge operation from the nozzle by the liquid droplet discharging unit. The control means performs preliminary discharge control in which a first liquid droplet is discharged from the nozzle onto a three-dimensional recording medium for maintenance of the nozzle, and image formation control in which, on the basis of image data of an image to be formed, a second liquid droplet is discharged from the nozzle onto the three-dimensional recording medium so as to form an image on the three-dimensional recording medium. In the preliminary discharge control, the discharge operation is controlled so that the volume of the first liquid droplet is equal to or less than the volume of the second liquid droplet and the velocity of the first liquid droplet is faster than the velocity of the second liquid droplet.
