Painting device, painting arrangement, method for painting a curved surface of an object, and use of an inkjet device for painting an aircraft

A method for painting a curved surface of an object, comprising:

• ejecting paint material from a paint material ejection device, wherein the paint material ejection device comprises a plurality of paint material ejection sub-devices, wherein the sub-devices are adapted to eject different paint materials onto the surface of an object to be painted, and wherein the plurality of sub-devices are adapted to eject paint materials for forming a three-dimensional texture on the surface of the object to be painted;
• wherein the three-dimensional texture is arranged as a riblet structure;
• mechanically guiding the paint material ejection device along a curved surface of an object by a guide device;
• and
• controlling the paint material ejection device and the guide device by a control device in such a way that by guiding the paint material ejection device along a predefinable path, and by predefinable ejection of paint from the paint material ejection device along the predefinable path a curved surface of an object to be painted is painted.
