Precise measurement of 2-propanol concentration in offset fountain solutions

It must, however, be stated that no ideal substitute for 2-propanol has as yet been found. If 2-propanol is still to be used to guarantee trouble-free high quality printing, then, not least for reasons of cost, the ground rule should be “As little as possible and only so much as absolutely necessary”. Besides accurate metering of 2-propanol when mixing the fountain solution, exact measuring of the 2-propanol concentration also takes place during printing production. As 2-propanol is continuously evaporating from the fountain solution during the printing process, the continuous or interval controlled measuring is the basis for metering additional 2-propanol.
