Supercalendering is a special finishing process used in paper manufacturing to make paper extra smooth and glossy. Think of it like ironing clothes, but for paper - the paper passes through a series of heavy rollers that press and polish it. This process is particularly important for making high-quality magazine paper, catalog paper, and other materials that need a shiny, smooth finish for good printing quality. Companies often look for people who understand this process because it's crucial for creating premium paper products.
