Abstract: A printer is configured for printing with conductive ink for applying a conductive pattern to a surface including a wheeling structure for moving the printer over the surface and a transfer unit for applying a layer of electrically conductive ink to the surface. To provide accurate printing with the ability to obtain fine tolerances, the transfer unit has a printing drum rotatable about a printing drum axis and defining a printing drum periphery moving between a first zone and a second zone by rotation of the printing drum. The printing drum periphery, in the first zone, receives the conductive ink and in the second zone transfers the ink to the surface.

Abstract: The present invention provides a method for producing a layer of organic material. The method comprises providing onto a substrate, under deposition conditions, a layer of a solution comprising said organic material dissolved in a solvent; optionally partially drying said layer of solution; thereafter annealing said layer of solution, said annealing being applied before said layer of solution has been dried out completely and the duration of said annealing being limited such that said layer of solution is not dried out completely during the annealing, said annealing inducing reflow of said layer of solution; and thereafter drying out said layer of solution, said drying out being controlled such that it is performed slower than it would be under deposition conditions. The resulting layer of organic material shows an improvement of both the micro quality and the macro quality, leading to obtaining a fully continuous film with minor surface roughness and an accurate line resolution and edge definition.
