Calender roll and process for operating the same. The calender roll includes a core, an elastic coating which extends over an operating width of the core, and an internal heat equalization system arranged to match the temperature of the axial ends to at least approximately a temperature of an axial center of the roll. The process includes forming a press nip between the calender roll and the mating roll, guiding a web through the press nip and within the operating width of the coating, and rotating the calender roll. In this manner, the internal heat equalization system substantially matches a temperature of the axial ends to a temperature of the axial center of the roll. The process may also include rotating the calender roll, and equalizing a temperature within the calender roll between axial ends of the calender roll and an axial middle of the calender roll.
