Abstract (en)
In the method for processing fountain solutions for offset printing oxygen contained in compressed air is added to the water to modify its surface tension and to improve its viscosity. Thereby the use of isopropyl alcohol can be avoided. The device for implementing the method includes a damping unit (5) containing a scoop roller (10) in a fountain solution tank (11) that is arranged ahead of the inking unit (4) and in which the fountain solution tank is provided with an air supply unit (15) driven by compressed air. <IMAGE>
