Title:
PRINTING DEVICE, CONTROL DEVICE, AND PRINTING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/024342
Kind Code:
A1
Abstract:
This printing device comprises: an inkjet head provided with a plurality of nozzles and a plurality of piezoelectric elements; a camera that captures an image of a droplet that is ejected from one of the plurality of nozzles and that lands on a target surface; and a control device that, on the basis of the image, acquires droplet brightness, which is the brightness of the droplet, and an orthographic projection shape, which is the shape of the orthographic projection of the droplet onto the target surface, calculates the volume of the droplet on the basis of on the droplet brightness and the orthographic projection shape, and adjusts a voltage applied to at least one of the plurality of piezoelectric elements on the basis of the calculated volume.
