Abstract

A method and apparatus for applying a liquid medium to a printing carrier in offset printing machines. It is suitable for processing media of different viscosity, such as low-viscosity dispersion lacquers or higher-viscosity bronze and effect printing inks. In order to guarantee precise metering, two function modules are assigned in an exchangeable manner to a forme cylinder in two bearings. If processing of low-viscosity media is required, the first function module, consisting at least of a metering roller and an applicator roller, is used. For processing higher-viscosity media, the second function module, consisting at least of a screened applicator roller and a chamber-type doctor, is used.
