5.6. Micro Embossing Processes
The term hot embossing or embossing can be used for a large scale of different structuring processes based on an embossing step. The following section will give a short overview of the manifold of these processes. Nevertheless, a clear definition of the terminology cannot be found in literature.
5.6.1. Roller Embossing

Using rolls instead of plates, continuous molding can be achieved with advantages regarding the molding times and disadvantages regarding the height and the aspect ratio of the molded structures (Fig. 5.24).
