Normal ceramic layers with a surface roughness value of Rz 2 – 3 get a shiny surface. The reflections caused by the gloss disrupt the functionality of photocells or lasers that are used for inspection. We have developed a solution that makes the gloss effect disappear. We are convinced that there are numerous attractive uses for this new roller. First and foremost, of course, is the production of foils. In addition, the inspection roller is also ideally suited for corona systems, display film systems and printing machines.
