The Dampening Sleeve is a synthetic non-woven, seamless, water shrinkable, fibrous composite covering for the dampening roller or form roller of an offset printing press. They absorb, store and meter fountain solution from the vibrator roller to the plate. Controlling ink-water balance is key to consistent printing. With Dampening Sleeves, youll get that control. Along with the latitude you need for consistent, high quality results on press.
