Abstract: A method for producing a device wherein, in a first production step, a translucent substrate is prepared, and wherein, in a second production step, a transparent material is printed onto the translucent substrate by a printing method. In the second production step, applications in the form of droplets of transparent material are arranged on the translucent substrate. In the second production step, an element which is formed from multiple applications and further applications is generated. The droplets to generate the element are deposited circularly in concentric rings, and the outermost deposited droplets have a first diameter, and the droplets deposited at a center have a second diameter that is different from the first diameter to build up a lens-like light-directing structure.

Abstract: The invention relates to a print head for printing optical structures on a substrate comprising an ejection device for ejecting at least one droplet of a printing ink towards the substrate in order to build up the optical structure, wherein the print head comprises a measurement means for contactless measuring at least one physical parameter of the at least one deposited droplet.
