Abstract

An ink duct for a rotary printing press wherein all or some of the surfaces of the ink duct are permanently coated with a substance which has a low surface energy of between 10 and 60 mN/m. As well as enabling the ink duct to be cleaned easily, the blending of the printing ink is improved owing to the reduced frictional resistance of the coated parts, which in turn leads to more uniform use of the ink-metering roller.
