    Abstract: A method of on-press developing a high-speed laser sensitive lithographic printing plate with ink and/or fountain solution is described. The printing member comprises on a substrate a photosensitive layer soluble or dispersible in ink and/or fountain solution and capable of hardening upon exposure to a laser. The plate is exposed with a laser and on-press developed with ink and/or fountain solution. At least a portion of the on-press development is performed with the plate under a yellow-red light or in substantial darkness, and at least a portion of the lithographic printing is performed under white light.

    Abstract: A method of processing an on-press developable lithographic printing plate involving the removal of overcoat after imagewise exposure and before on-press development is described. The plate comprises a substrate, an on-press ink and/or fountain solution developable photosensitive layer, and an overcoat. The laser imaged plate is stripped off the overcoat, and then under a white room light mounted on press and developed with ink and/or fountain solution. Here the plate is capable of hardening upon exposure to a laser, has limited white light stability before the removal of the overcoat, and has significantly improved white light stability after the removal of the overcoat.
