Abstract
A damping roller for the damping unit in a printing press has a roller body that carries a glass, glass ceramic, or enamel outer material, layer, or coating. Suitable coatings can be produced, for example, by enamelling, plasma spraying, or attaching the outer layer to the body with a sealing compound. In another embodiment, the glass, glass ceramic, or enamel material acts as the self-supporting roller member accommodated solely by the journals. Preferably, the outer surface of the roller is polished. The damping roller of the invention has the ability to dispense an optimum amount of damping medium while eliminating or reducing damping medium additives such as alcohol to less than 6% of the total mixture.
