    Abstract: A negative-working imageable element having an imageable layer on a substrate can be used to form an imaged element by imagewise exposing it to form exposed and non-exposed regions in the imageable layer. The imageable element also has a water-soluble topcoat disposed on the imageable layer. With or without a preheat step, the water-soluble topcoat is at least partially removed with water or an aqueous solution that incompletely or not at all removes the non-exposed regions of the imageable layer. The element is then mounted in a printing press and contacted with a fountain solution, a lithographic printing ink, or a combination of a fountain solution and a lithographic printing ink, thereby removing non-exposed regions of the imageable layer at the beginning of the printing operation.
