Printing
By humidifying the atmosphere around printing presses, reel-stand areas and paper stores, static build-up, web-breaks and paper curl can be dramatically reduced.
Paper receives and loses moisture readily as the surrounding humidity changes . A moisture content of 5 to 7% provides suitable strength and workability. To achieve this moisture content, a RH of 50 – 55% must be maintained.
Benefits
Eliminates static electricity and decreases or eliminates curl and warping.
Increases productivity with higher speeds and decreases rejects.
Improves sheet separation
Allows better ink transfer and enhances ink and glue chemistry balance.
Aids in dust suppression and produces evaporative cooling
Improves conditions of workplace and reduces heat load through evaporative cooling
