A method and device for laser-induced marking. The method comprises providing an article having a marking surface including a non-flat area, providing a first laser transfer foil, providing a first laser unit for emitting first laser light, providing a first hard adaptor that is essentially transparent to the first laser light, the first hard adaptor having a contacting surface that essentially is a negative of at least a part of the marking surface of the article, contacting the first laser transfer foil with the marking surface of the article by the first hard adaptor such that the first laser transfer foil is arranged between the marking surface of the article and the contacting surface of the first hard adaptor, and irradiating the first laser light through the first hard adaptor onto the first laser transfer foil. The device comprises a first laser unit for emitting and scanning first laser light over a first transfer area, a first foil unit for providing a first laser transfer foil at the first transfer area, a carrier for providing an article at the first transfer area, the article having a marking surface comprising a non-flat surface area, a first hard adaptor that is transparent for the first laser light, the first hard adapter having a first contacting surface that is essentially a negative of the non-flat surface area of the marking surface, and a contacting unit for bringing the first laser transfer foil in contact with the marking surface by causing the first contacting surface to move one of the first laser transfer foil and the marking surface towards one another. |
