The transfer roller is mounted rotatably about an axis of rotation to the frame, the nozzle arranged for dispensing lacquer into depressions while the transfer roller is rotated. The transfer roller is configured to roll with the outside contact surface on a work surface of a work piece for transferring lacquer from the depressions to the work surface, the depressions formed and distributed over the outside contact surface in a predefined pattern having a main orientation direction. Efficiency of lacquer transfer can be increased as the pattern is arranged such that the main orientation direction extends other than perpendicular to the axis of rotation of the transfer roller.
