A method for forming an image on a printing plate intermediate having a radiation transparent removable coating layer is disclosed. An image mask, opaque to ultraviolet radiation, is applied to the coating layer with an ink jet system. After the plate intermediate is exposed with ultraviolet radiation, the image mask and coating layer are removed, and plate intermediate developed.

The invention utilizes ink jet liquid droplets from one or more printer heads to form an image upon the surface of a printing plate corresponding to digital information depicting the image as provided by a digital computer system which is in digital communication with the printer heads. The droplets from the printer head comprise resin forming reactants which polymerize on the plate surface, alone or in combination with reactants precoated on the plate, to form a printable hard resin image. The resin image so formed provides a lithographic printing plate useful for extended print runs.

Lithographic plate compositions and a method for their production have been discovered that are especially useful in conjunction with digitally controlled lasers to directly construct printable images on lithographic plates. The plates comprise a substrate and an ablatable polymeric coating on the substrate where the ablatable, imageable coating is prepared by in situ or solution polymerization of conjugated monomers deposited on the plate by vapor deposition or in solution. Examples of such monomers are thiophene, pyrrole and aniline.

Lithographic printing plates for wet or waterless offset printing are disclosed which can be imagewise exposed using a digitally controlled IR laser. The invention comprises a laser imagable lithographic printing plate comprising a substrate, a photosensitive coating on the substrate, and a water soluble laser ablatable top coating containing dyes or polymers that absorb infra-red, ultraviolet and visible light. Laminated transparent polymer films and/or peelable polymeric coatings films can be interposed between the coated substrate and a water soluble and/or organic solvent soluble laser ablatable top layer to augment plate production or image inscription on the plate.
