Abstract: A method is provided for surface-selective coating of a surface of an individual physical document, in particular a card-like document, with a liquid coating. The method includes: receiving or generating an actual image information by image sensors, which represents an actual image of the surface; and comparing the actual image information with reference image information, which represents a reference image of a reference surface corresponding to the surface, to determine, based on possible deviations between the actual image and the reference image, any deformation of the surface compared to the reference surface and to generate deformation information representing said deformation or alternatively the absence thereof. A coating device is then controlled based on coating information determined based on the deformation information and on geometry information that defines a target shape of a partial surface of the surface to be provided with the liquid coating.
