A method of on-press developing a lithographic printing plate with ink and/or fountain solution involving the utilization of a plate holder for transferring the exposed plate from the imager to the lithographic press is described. The plate comprises on a substrate a photosensitive layer capable of hardening or solubilization upon exposure to a laser, and the non-hardened or solubilized areas of the photosensitive layer are soluble or dispersible in ink and/or fountain solution. The plate is exposed with the laser on an imager and placed in a plate holder to transfer to the press for development with ink and/or fountain solution and lithographic printing. The plate holder is preferably light-tight so that the plate in the plate holder is shielded from the room light.
