Abstract

In a printing press, ink fountain keys are disposed to be movable toward and away from an ink fountain roller of an ink fountain to allow them to have a predetermined gap therebetween and hence the amount of ink to be fed to a downstream roller to be determined. The ink fountain roller is rotated while ink is prevented from being fed to the downstream roller. At least one of the ink fountain keys is moved so as to allow the at least one of the fountain keys to change a position thereof relative to the ink fountain roller of the ink fountain with time. With this arrangement, it is possible to improve an ink kneading effect produced by the rotation of the ink fountain roller without the necessity to manually knead ink in the ink fountain by the operator and the necessity to provide any ink kneading device or unit independently of the printing press.
