Techniques, processes and structures are disclosed for providing markings on products, such as electronic devices. For example, the markings can be formed using physical vapor deposition (PVD) processes to deposit a layer of material. The markings or labels may be textual and/or graphic. The markings are deposited on a compliant layer that is disposed on a surface to be marked. The compliant layer is arranged to isolate the surface to be marked from the layer of material deposited using the PVD process.
