Calendering is an important finishing process in paper manufacturing where paper passes through large metal rollers (called calenders) to make it smooth and glossy. Think of it like ironing clothes, but for paper. This process controls how smooth or shiny the final paper product will be, which is crucial for products like magazines, catalogs, or high-quality printing paper. The process can also control the paper's thickness and surface texture. When you see this term in a resume, it usually indicates experience with paper finishing equipment and quality control.
