Abstract
The invention concerns a method for regulating the concentrations of components of additives in a printing process liquid for maintaining predetermined desired concentrations of components of additives in a printing process liquid, wherein the actual concentrations of components are determined followed by redosing of measured components to a predetermined desired concentration. The method is characterized in that the components to be measured are spectroscopically detected. The invention also concerns a device for regulating the concentrations of components of additives in a printing process liquid comprising a measuring means for measuring the concentrations of at least part of the components in the process liquid, comprising a control loop and a means for redosing at least part of the components, wherein the measuring means comprises at least one spectrometer.
