Electroplated Micro-Labelling as Copy Protection

Abstract

In order to achieve good product quality in electroplating, disturbance variables such as the "dog bone" effect must be avoided. In this work, this approach was used to develop a method for marking as product protection. With a defined structure and optimal parameters, it is possible to deposit unique visually non-differentiable layers on suitable substrates. The deposited layers and their local distribution were characterized by confocal laser microscopy, X-ray fluorescence analysis and laser interference measurements and analyzed qualitatively as well as quantitatively. It thus provides interested parties with an essentially traditional process that can lead to new innovations with the chosen approach.
