Abstract (en)

[origin: EP1500499A1] A method for maintaining the quality of an offset printing system, and ensuring minimum down time, has the concentration of the chemical, or groups of chemicals, in the process tank (2) continuously monitored (6). Any reduction in any chemical is corrected by a top up system comprising separate reservoirs (K) of chemicals and dosing pumps (7). The system is suitable both alcohol based fluid as well as non alcohol fluids.
