ABSTRACT:
A dampening water controller for controlling the concentration of an etching solution in dampening water circulatively used in offset printing, includes an ion concentration measuring means capable of measuring the concentration of at least one kind of ion (object ions) selected from specific anions or cations contained only in an etching solution in dampening water. Information on the measured concentration of the ions in the dampening water is output. A dampening water temperature measuring device capable of measuring the temperature of the dampening water and outputting information on the measured temperatures is provided. Also, an ion concentration information correcting device is provided capable of correcting the information on the measured concentration of the ions in the dampening water, in accordance with the information on the measured temperature of the dampening water. The controller also includes an etching solution concentration adjusting device capable of adjusting the concentration of the etching solution in the dampening water, in accordance with the corrected information on the ion concentration.
