ABSTRACT:
Method and apparatus for metering liquid media of different viscosity and preferably for metering liquid media for application to a printing carrier in varnishing units. In order to assure precise metering, exchangeable metering systems are assigned to a forme cylinder. If processing of low-viscosity media is required, a metering roller and an applicator roller of identical external diameter but different surface hardness are used. For the processing of higher-viscosity media, a chamber-type doctor with a screened applicator roller is used.
