Abstract: A device as well as method for treating without developing an imagewise exposed lithographic printing plate is disclosed. The device comprises a structure for providing a treating solution to the exposed plate. The exposed plate comprises on a substrate a photosensitive layer having hardened areas and non-hardened areas (for negative plate) or solubilized areas and non-solubilized areas (for positive plate). The non-hardened or solubilized areas of said photosensitive layer is removable with ink and/or fountain solution on a lithographic press. The treatment of the imagewise exposed plate allows one or more enhanced properties for the plate before on-press development, such as improved white light stability, enhanced or formation of visible image, improved hydrophilicity, or improved on-press developability.
