Abstract
In an inking apparatus for use in a printing press, an ink pan located below a plate cylinder is separated into a first part which accommodates a furnisher roll for furnishing ink and a second part which receives contaminated ink containing foreign substance scraped off a doctor blade. In order to prevent the ink within the second part from flowing directly into the first part, partitions are provided, or alternatively the second part is positioned lower than the first part, or alternatively the first part and the second part are comprised of two separate receptacles. The supply of ink to the plate cylinder may be carried out by any suitable means other than the furnisher roll. The ink pan may be configured in the form of an exclusive receptacle adapted to receive only the contaminated ink containing foreign substance scraped off the doctor blade, the supply of ink to the plate cylinder being effected without passing through the ink pan. Thus, high-grade quality ink to be supplied to the plate cylinder is prevented from contamination.
