Abstract
To delete undesired ink-receptive areas on a wet lithographic printing construction, an oleophobic material is applied to the hydrophilic surface of the plate that has suffered contamination and/or scratching, and allowed to cure. So long as the hydrophilic surface is capable of permanently bonding the oleophobic deletion agent, the areas to which that agent has been applied will not accept ink.
