Abstract: A method and apparatus for in-place repair of the outer surface of a cylinder in an offset lithographic printing press. The steps of the method are performed while the cylinder remains in the printing press. The steps are: cleaning the outer surface of the cylinder; applying an epoxy coating on the cylinder; drying the coating; inspecting the coating after drying to locate any high spots or low spots; and removing any high spots and filling any low spots. In the preferred embodiment, application of the epoxy coating is carried out with an applicator blade mounted on the printing press frame adjacent to the outer surface of the cylinder to be repaired. The applicator blade is an elongated member of substantially the same length as the cylinder and is adjustably mounted parallel to the axis of the cylinder at an adjustable distance from the outer surface of the cylinder, said distance being equal to the desired thickness of the epoxy coating to be applied to the outer surface of the cylinder.
