ABSTRACT:
An ink-furnishing apparatus for continuously supplying ink to an ink cylinder from an ink rail even during high speed operation of the ink cylinder. An ink transfer surface of the ink rail has a first solid substance which is superior to a cast iron constituting the ink rail in terms of separation of ink therefrom. A peripheral surface of the ink cylinder has a second solid substance which is superior to the first solid substance in terms of adhesion of the ink thereon. While said first solid substance has a surface which makes a larger contact angle with a surface of the ink than a contact angle made between the surface of the ink and the surface of cast iron constituting said ink rail, said second solid substance has a surface which makes a smaller contact angle with the surface of the ink than said larger contact angle.
