ABSTRACT:
A cylinder setting mechanism for an offset printing device in which a blanket cylinder moves eccentrically about a first pivot point to make contact with the master cylinder so that it can be inked and then subsequently moved eccentrically about a second pivot point to make contact with the impression cylinder to transfer the image to paper. The invention enables the first and second pivot points to be adjusted to compensate for wear, plate thickness, and paper stock. In addition, a stop is provided to insure that there is a predetermined contact pressure between the surfaces of the blanket cylinder and the master cylinder. The first eccentric adjustment is made by rotating an eccentric tube at only one end about a first pivot point. The blanket cylinder rotates about the outside of the eccentric tube. The second adjustment is made by rotating an eccentric shaft on which the eccentric tube is mounted to adjust the position of the blanket cylinder in relation to the impression cylinder.
