Title of the invention: Dampening device for an offset printing press The scope of the claims for utility model registration and the brief description of the drawings are amended as follows. [Claims for Utility Model Registration] 1. A pump that pumps water from a water supply source, a mixer that mixes additives with the water to create dampening water, and a plurality of pumps that spray the dampening water onto a roller or plate surface. In a dampening device for an offset printing press, which is equipped with a spray dampener having a spray nozzle, at least dampening water remaining in the spray nozzle of the spray dampener is removed after, before, or during use of the printing press. A dampening device for an offset printing press, comprising means for supplying forcedly discharged air between the mixer and the spray dampener . 2. Equipped with a pump that pumps water from a water supply source, a mixer that mixes additives with the water to create dampening water, and a spray dampener that has a plurality of spray nozzles that sprays the dampening water onto a roller or plate surface. In a dampening device for an offset printing press, after, before, or at least during use of the printing press, the pressure pump and the spray dampener are directly connected by bypassing the mixer, and at least the spray dampener is connected directly to the pressure pump and the spray dampener. A dampening machine for an offset printing machine, comprising a bypass that supplies water from the water supply source between the mixer and the spray dampener as washing water for forcibly discharging dampening water remaining in the spray nozzle. equipment. 3 Equipped with a pump that pumps water from a water supply source, a mixer that mixes additives with the water to create dampening water, and a spray dampener that has a plurality of spray nozzles that sprays the dampening water onto a roller or plate surface. In a dampening device for an offset printing press, after, before, or at least during use of the printing press, the pump and mixer are bypassed and the water supply source and the spray dampener are directly connected, and at least The spray dampener is characterized by comprising a bypass including a pump that supplies water from the water supply source between the mixer and the spray dampener as cleaning water for forcibly discharging dampening water remaining in the spray nozzle of the spray dampener. Dampening device for offset printing presses. 4. A dampening device for an offset printing machine comprising a dampening water storage means, a pump for pumping the dampening water from the storage means, and a spray dampener having a plurality of spray nozzles for spraying the dampening water onto a roller or plate surface. In the apparatus, after, before, or during use of the printing press, air is supplied to the pressure pump and the spray dampener to forcefully discharge dampening water remaining in at least the spray nozzle of the spray dampener.
