Roller pressure settings
New damper covers must be set for proper pressure after they are installed.
The following procedure can be used to check the dampener roller pressure
setting.
Prepare the dampening system for operation. Check the dampness of the
form roller. Let the dampener form roller run against the plate on the plate
cylinder for a few minutes. Lift the form roller and stop the press.
When the press is stopped, place two 1” X 8” strips of 0.005” thick acetate
sheet between the form rollers and the plate. Place one strip each at both
the ends.
