Beschreibung
Zusammenfassung:	A method and printing system for printing a three-dimensional structure, in particular an optical component, by depositing droplets of printing ink side by side and one above the other in several consecutive depositing steps by means of a print head. In each depositing step a plurality of droplets is ejected simultaneously by a plurality of ejection nozzles of the print head. The print head is moved relative to the deposited droplets in a moving step performed between at least two consecutive depositing steps in such a manner that the droplets deposited in the same position in the at least two consecutive depositing steps are ejected at least partly from two different ejection nozzles.
