Abstract
A cylinder setting mechanism for a single or multi-color offset printing device in which a blanket cylinder moves eccentrically about a first pivot point to make contact with a 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 ensure that there is a predetermined contact pressure between the surfaces of the blanket cylinder and the master cylinder. The stop is automatically adjusted when the toggle is adjusted for a different thickness plate so that the desired offset printing pressure between the master and blanket cylinder surfaces is held at the optimum level.
