The present invention concerns an apparatus, a process and a cartridge for producing and transferring a thin film to a substrate withdrawing the thin film. The apparatus includes the substrate, a transfer lip, a gap defined between the substrate and the transfer lip and a liquid film supported on the transfer lip and carrying a thin film in a direction towards and into the gap, the liquid of the liquid film forming a capillary bridge spanning the length of the gap and supporting the thin film over the gap onto the substrate. The process includes the steps of supplying the liquid film, positioning the transfer lip and substrate, supporting the liquid film towards and into the gap, forming the capillary bridge and withdrawing the thin film. The modular cartridge is also described.
