Only the film analysis device is capable of measuring and analyzing these characteristics, which depend on many influencing factors.<\/p>\n\n\n\n<p>The main difficulties arise in duplex processing, i.e., when multiple layers are pressed together and differing characteristics occur between the individual layers.
