This contribution illuminates the potential of hyperspectral imaging for the characterization and permanent monitoring of web-like materials, which are produced or converted in continuous roll-to-roll processes such as coating, printing, lamination or finishing. It is shown that this experimental technique is a mighty process analytical tool, which is able to provide extensive information about the corresponding technical processes, which might be used for both quality assurance and control of the production process itself. A broad range of specific applications in the various converting technologies is presented in which parameters such as the degree of conversion, the application weight or the moisture content after drying are in the focus of interest. Moreover, it is discussed how hyperspectral imaging can be efficiently adapted to very wide widths (several meters) of the web.
