ABSTRACT:
The present invention has as an object to provide an inking device which prevents the generation of vibration in rollers and is capable of supplying the amount of ink uniformly all the time to the surface of printing plate in the direction of its width. The inking device of the invention is constructed such that the distance between the bottom of the ink pan and the surface of the ink fountain roller, the distance between the surface of the ink fountain roller and the surface of the ink transfer roller and the surface of the roller next to it in the downstream direction are made smaller as the distance proceeds downstream. The ink is transferred from the upstream side to the downstream side, and during this ink transfer, the ink distribution is regulated uniformly in the direction of roller width by means of a doctor blade, etc. Further, the circumferential surface speeds of the rollers are variable, and the vibration of the inking device is prevented by matching the circumferential surface speed of the ink transfer roller to the circumferential surface speeds of the rotating rollers on the downstream side.
