Abstract
The invention is directed to the development of lithographic printing plates by the application of a thin film of developer solution to each plate in a controlled manner using a wire-wound coating device that resists wetting-out of the solution. The exposed surface of the wire-wound coating device has a surface energy of no more than 24 dynes/cm, preferably less than about 20 dynes/cm, which can be achieved, for example by PTFE or FEP. The fluid is gently fed onto the wire-wound device by simple volumetric displacement.
