Abstract

A device for lacquer transfer includes a frame, transfer roller with circumferential lateral wall, nozzle for dispensing lacquer, and hardening unit, the hardening unit formed as a UV-light unit for hardening the lacquer in a contactless way by emitting UV-light, and is within an interior space defined by the transfer roller. The lateral wall of the transfer roller is transparent for UV-light, and the hardening unit is arranged such that UV-light is emitted towards the work surface upon which the lateral wall of the transfer roller rolls, to harden the lacquer after it being transferred to the work surface. Using the device, lacquer transfer can occur from the transfer roller to the work surface more reliably. The device includes a light shield between the hardening unit and outside contact surface with at least a portion of the outside contact surface provided with lacquer is shielded from UV-light emitted from the hardening unit.
