Metering Process

Standardizing the offset printing process should also include standardization of the composition of the damping solution. The prescribed addition should be respected, since all effective ingredients are matched to the recommended concentration for use. Over-and under-metering are equally inadvisable, and can cause printing and corrosion problems in the long term. It is recommended to use automatic metering systems for the damping solution additive, the isopropanol, and re-hardening agents, in case these are required.

For keeping the isopropanol content in the damping solution constant, there are now new metering systems available which are based on different working principles, and are a lot more accurate than the well-known float systems. They perform accurately even in the range under 5 volume percent alcohol.

All of the metering, cooling, and circulation systems, which are in contact with reconditioned water or damping solution, must be free from copper or brass parts and should instead consist of plastic or stainless steel.
