Abstract: Provided is a lithographic printing plate comprising a support substrate (106) having disposed thereon an ablative-absorbing layer (102) and, optionally, a durable, ink-accepting surface layer (100) that is not ablative-absorbing. The ablative-absorbing layer may contain a high weight per cent of an organic sulfonic acid component. The printing plate may further comprise a hydrophilic polymeric layer (104) interposed between the ablative-absorbing layer and the substrate. The printing plate also comprises a primer layer underlying the ablative-absorbing layer with an adhesion-promoting agent, such as a zirconium compound, present in the primer layer. Also provided are methods of preparing such lithographic printing plates, and methods of preparing imaged lithographic printing plates by imagewise exposure to a laser and a subsequent cleaning step with water or with a cleaning solution.

Abstract: Methods and apparatus for lithographic imaging without ablation function by irreversibly debonding intermediate printing-plate layers, thereby rendering at least the surface layer removable by cleaning to expose, in an imagewise pattern, an underlying layer having a different affinity for ink and/or an adhesive fluid for ink. In contrast to ablation-type systems, it is unnecessary to destroy a plate layer, thereby reducing power requirements and facilitating increased imaging speeds.

Abstract: A positive-working, ablation-imagable lithographic printing plate precursor can be imaged and used for lithographic printing without wet processing. This precursor has a sulfuric acid or phosphoric acid anodized aluminum-containing substrate, a crosslinked hydrophilic inner layer comprising a crosslinked polymer derived by using a crosslinking agent that comprises at least two aldehyde groups, and an acidic compound. Over the crosslinked hydrophilic inner layer is an oleophilic outer layer comprising an infrared radiation absorber and an oleophilic polymer. The precursor also has a copolymer comprising randomly recurring units derived from each of a (meth)acrylamide and vinyl phosphonic acid. This copolymer is present either within the crosslinked hydrophilic inner layer, as part of a different copolymer layer between the crosslinked hydrophilic inner layer and the substrate, or in both places.
