Abstract
Disclosed is a printing apparatus for a 3D surface, which performs printing by ejecting a droplet onto a 3D surface and controlling an electric field on an impact path of the droplet, the printing apparatus including: a ejecting environment information provider configured to provide ejecting environment information between a nozzle and an impact point; and a controller configured to predict a result of printing on an actual substrate by accumulating previous printing results according to printing conditions and the ejecting environment information into a database, and perform the printing on the 3D surface while changing the printing conditions provided by the database based on the ejecting environment information provided by the ejecting environment information provider.
