    摘要： The present invention provides a method for developing a lithographic plate on a printing press without the requirement of bath processing, the printing press equipped with means for delivering ink and aqueous fountain solutions to the plate, the preferred plate having in order (a) a substrate; and (b) a photoresist photohardenable upon imagewise exposure to actinic radiation, the photoresist comprising (i) a macromolecular organic binder; (ii) a photopolymerizable ethylenically unsaturated monomer having at least one terminal ethylenic group capable of forming a high polymer by chain-propagated polymerization, (iii) a polymerization initiator activatable by actinic radiation, and (iv) a disperse hydrophilic microgel. According to a product aspect, the present invention also provides a lithographic plate, configured as indicated, with the further combination therewith of an on-press removable polymeric overcoat.

    摘要： The present invention is directed to a method for the on-press development and printing of images. The method generally comprises the steps of providing a lithographic printing plate precursor element comprising a lithographic hydrophilic printing plate substrate, a photohardenable photoresist, and a layer of polymeric protective overcoat; imagewise exposing the precursor element to actinic radiation through said photoresist and overcoat layer sufficiently to photoharden the photoresist in exposed regions and provide a latent image in said photoresist layer; placing the precursor element onto a lithographic printing press; and running the press, whereby printing fluid effects removal of the overcoat and development of said latent image. In particular modes of practices, the method utilizes an overcoat having incorporated therein a water or fountain soluble or dispersible crystalline compound. The overcoat can be used as an oxygen barrier and/or to provide a non-tacky surface on the printing plate. By the incorporation of the crystalline compound, on-press removability of the overcoat is facilitated.

    摘要： Compositions, systems, and methods for providing smudge resistant and durable ink-jet images having good optical density are provided. Specifically, a system for printing durable ink-jet ink images can comprise a first ink-jet pen containing an ink-jet ink and a second ink-jet pen containing a fixer composition. The ink-jet ink can comprise a first liquid vehicle and a colorant. The fixer composition can comprise a second liquid vehicle, and from 0.5 wt % to 5 wt % of a cationic copolymer of an epihalohydrin and an amine. Upon overprinting or underprinting the fixer composition with respect to the ink-jet ink on a substrate, a durable image can be formed.

    摘要： In a four pen ink jet printer comprising cyan, yellow, magenta, and black inks, a clear liquid is applied to printed ink on a print medium via a fifth pen, thereby fixing the colorants, which in turn improves the durability of the printed ink. The clear fixer fluid comprises at least one organic acid and, optionally, a salt of at least one polymeric acid.
