ABSTRACT:
Disclosed is an ink furnishing apparatus in a lithographic printing press with a keyless system which performs printing by furnishing a relatively high viscous ink and dampening water to printing plates on a plate cylinder. A first shearing force is exerted on the ink upon drawing out the ink deposited on a peripheral surface of a fountain roller through a first gap between an ink fountain and the peripheral surface of the fountain roller by rotation of the fountain roller, and a second shearing force is exerted on the ink due to a difference of peripheral speeds of the fountain roller and a first intermediate roller upon transition of the ink from the peripheral surface of the fountain roller to the peripheral surface of the first intermediate roller across a second gap between the peripheral surface of the fountain roller and the peripheral surface of the first intermediate roller, thus, water is separated from the ink.
