A method for improving the characteristics of wetting water in offset printing, comprises at least the steps of controlling and holding constant in time the pH value of the wetting water and controlling and holding constant in time the value of the wetting water electric conductivity. The apparatus for carrying out the method comprises, in an operatively and functionally intercoupled relationship, means for supplying the wetting water, means for filtering the supplied wetting water, designed to provide an actively filtered wetting water, magnetic means adapted to subject the filtered wetting water to a continuous and strong magnetic processing, pH controlling means, adapted to control the wetting water pH at a preset acid pH value, and means adapted to control the wetting water electrical conductivity at a set conductivity value. |
