Abstract
Fountain solution is supplied to printing plates (2) on a plate cylinder (1) in an operating offset printing press, normally by means of a spray bar (5) containing nozzles for the fountain solution. The actual amount of the fountain solution on the printing plates is assessed by means of one or more plate sensor (8). The sensor(s) (8) will scan the print plates (2) and measure at predetermined points. The assessed values are transmitted to a control unit (9), which controls the supply of fountain solution from the spray bar to the printing plates (2).
