Verfahren und Vorrichtung zur kontinuierlichen Messung und Regelung der Zusammensetzung einer Feuchtmittellösung für den Offsetdruck

摘要

The wetting-agent solution proposed contains of water and at least one organic solvent miscible with water. The speed of sound in the solution is measured and, from the value obtained, a control signal is generated to keep the composition of the solution constant.
