Apparatus and method for conditioning dampening solution for an offset printing press

An apparatus and a method for conditioning dampening solution for an offset printing press, include a cation exchanger for the removal of salt-forming ions from the dampening solution. The operation of the cation exchanger leaves the pH of the dampening solution unchanged. The apparatus includes a c...

Beschreibung
Zusammenfassung:	An apparatus and a method for conditioning dampening solution for an offset printing press, include a cation exchanger for the removal of salt-forming ions from the dampening solution. The operation of the cation exchanger leaves the pH of the dampening solution unchanged. The apparatus includes a control device based on measuring the water hardness of the dampening solution for the supply of thedampening solution to the cation exchanger.
