特徴とするインキング装置。[Scope of Claim for Utility Model Registration] A delivery roller is provided between an ink source roller that rotates at a low circumferential speed and a doctor roller that rotates at a high circumferential speed, each of which is equipped with a drive mechanism, and the ink supplied to the surface of the ink source roller is transferred to the surface of the ink source roller. In the inking device of an offset rotary press, in which a constant film thickness is created by an ink supply blade and transferred to a doctor roller via a delivery roller, the delivery roller is equipped with a drive mechanism so that the peripheral speed of the delivery roller is approximately the same as the peripheral speed of the doctor roller. An inking device characterized in that the peripheral speed ratio of the ink source roller and the delivery roller is 0.005 to 0.025.
