An apparatus for supplying offset printing presses with a cooled damping solution uses a damping tray. The damping tray is subdivided into two distinct portions. A reserve portion contains concentrated solution supplied from a source of damping solution. The distribution solution communicates with a ductor roller. Restrictive holes formed in the partition dividing the two portions of the tray have a flow rate that is directly related to the amount of damping solution being used by the ductor roller in the printing press. This flow rate being very small, allows flow only from the reserve portion into the distribution portion of the tank.
