Abstract: The invention relates to a method for printing a surface (2) with a fluid which contains an organic semiconductor material. The fluid is transported from a storage container (7) through a supply line (5) to a printing head (3), which can be moved over the surface (2), and printed onto the surface (2) by the printing head (3). At least one part of the fluid which is transported through the supply line (5) to the printing head (3) is returned to the storage container (7) via a return line (6), wherein a fluid circuit is formed, and the fluid in the fluid circuit flows through a cleaning device (12) with which the fluid is cleaned. The fluid returned to the storage container (7) flows around and surrounds the fluid being transported in the supply line (5) to the printing head (3) at least in some regions.

Abstract: The present invention relates to vessels comprising a formulation including at least one organic semiconductor, wherein the formulation is in contact with at least one absorption material. The invention further describes a process for producing the vessel and for the use thereof.

Abstract: In the case of a method for operating a printing device (1), wherein a fluid that is provided for a printing procedure is supplied from a fluid storage container (6) by way of a supply line (14) to a printing head (13) so as to be able to be applied by the printing head (13) onto a surface, the fluid in a purification circuit (2) is conveyed through a purification installation (8), and by way of a contamination-measurement installation (11) a key contamination indicator of a fluid-specimen quantity in the purification circuit (2) is determined such that a printing procedure by way of which the fluid is dispensed from the printing head (13) commences only once the key contamination indicator has undershot a first threshold value.
