Copper rollers Last longer than the Rilsan Rollers, Ink stripping is a rarity, Copper rollers also have excellent thermal conductivity, which makes them suitable for temperature-controlled inking systems where precise temperature management is essential for ink viscosity. Of course if roller...
Used 'water stops' for many years on our web presses. Also used air bars (air curtain) on the rollers to reduce the amount of moisture on the ends. Water stops much cheaper and requires far less technology.
