Abstract:
1. A method of kneading ink stored in an ink fountain of a printing press, in which an ink fountain roller rotates so as to make ink adhere to a circumference thereof and feed ink therefrom to a downstream roller, at least one ink fountain key that is aligned in a first direction parallel to the axis of the ink fountain roller and disposed so as to be moved back and forth in a second direction orthogonal to the first direction, thereby allowing each of said at least one ink fountain key and the ink fountain roller to have a predetermined gap therebetween and hence the amount of ink to be fed to the downstream roller to be determined, comprising: rotating the ink fountain roller while preventing ink from being fed to the downstream roller; and moving at least one of the at least one ink fountain key in the second direction during the rotation of the ink fountain roller so as to allow the at least one of the at least one ink fountain key to change a position thereof relative to the ink fountain roller of the ink fountain with time.
