Abstract
A system for at least partly decoupling the control of sheet finish and sheet caliper in a calender stack is disclosed. The system includes a heating device for heating the sheet with dry heat substantially immediately before the sheet is pressed by an upstream nip of the calender stack and a moisturizer for moisturizing the sheet substantially immediately before the sheet is pressed at a downstream nip of the calender stack. The sheet is moisturized without substantially altering the sheet temperature.
