Calendering process Basic mechanisms in calendering A combination of calendering and paper parameters determine the amount of compression of the paper and the final paper properties after calendering (Figure 1). The main calendering parameters affecting the result are the pressure in the calender nip, the residence time of compression and the roughness of compressive surfaces.
