A lithographic printing plate comprising a substrate, a plurality of particles provided in an array on a surface of the substrate, and a layer of a light sensitive material on the surface of the substrate, the particles being arranged between the surface of the substrate and the layer of light sensitive material so that formations are provided on the surface of the layer of light sensitive material as a result of the particles under the layer. The particles can be deposited on the surface by a dry deposition technique, for example using a plasma. The particles facilitate removal of air from the space between the plate and a film positioned over the plate for exposure. |
