Use of Steam Showers on Soft Calenders and Supercalenders to Improve Print Quality, 1994 Finishing and Converting Conference Proceedings
K. C. Mann
The use of soft calenders and supercalenders to improve sheet gloss and smoothness for improved printability is well documented. Through a better understanding of the mechanisms of calendering it will be easier to understand how using steam showers on soft calenders and supercalenders can enhance the production of gloss and smoothness by increasing the moisture and temperature of the surface fibers. Utilizing a Coanda nozzle steam actuator will further improve the performance of calendering operations. A good understanding of the importance of controlling the process steam properties is also critical for the effective use of steam showers on soft calenders and supercalenders.
