METHOD AND DEVICE FOR ROTATIONAL MOULDING OF SURFACE RELIEF STRUCTURES

摘要

The present invention relates in a broad aspect to a method and a device for applying structures to a medium being conveyed on a length. The method and device utilise a moulding process in which micro structures are moulded into/onto the surface of the medium. In a specific embodiment, the present invention relates to a process faciliting the replication of microstructures in a conventional printing machine. The replication method is integrated as a part of the machine, thus making it possible to perform the application of microstructures in-line. As the replication of the microstructure takes place in-line, the application of, e.g., holograms will be in register with the printed material.
