(57) Abstract: An untreated printing plate for forming a photosensitive article having a protective topcoat layer is disclosed. The topcoat layer may be a water soluble or water dispersible polymer, sol, salt, or mixture thereof. The hydrophilic protective topcoat is removed during printing by the action of the fountain solution and / or the ink. A protective topcoat layer can provide an untreated printing plate that is protected from contamination during handling, suppresses odor during image formation, and provides a roll-up action during printing. |
