Abstract: A method of deactivating an on-press ink and/or fountain solution developable lithographic printing plate 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, deactivated, and then on-press developed with ink and/or fountain solution. The deactivation is carried out by overall applying to the plate a deactivating agent, heat, or a radiation that has different wavelength from the laser and does not cause hardening of the photosensitive layer. The deactivation allows the plate to be handled on press under white light or other light that is unsafe for a non-deactivated plate.
