Abstract: Wet lithographic printing members for imaging by an inkjet printer using pigment-based aqueous ink and method for calibrating the amount of the inkjet ink to be injected in solid areas of an image are disclosed. An exemplary printing member can comprises a base substrate and a top hydrophilic coating layer having a thickness in the range of 2 to 10 microns above the base substrate. A volume of less than 10 nl/mm2 of inkjet ink is used in order to image areas in which the image is solid. Areas of the top hydrophilic coating layer, which are imagewise covered by aqueous pigmented inkjet ink, become hydrophobic. In some embodiments after imaging, the surface of the imaged printing member can be treated with acidic colloidal silica solution. Exemplary treatment can comprise wiping the surface of the imaged printing member with the acidic colloidal silica solution.

Abstract: Wet lithographic printing members for imaging by an inkjet printer using pigment-based aqueous ink and method for calibrating the amount of the inkjet ink to be injected in solid areas of an image are disclosed. An exemplary printing member can be a lithographic printing plate that comprises a base substrate and a top hydrophilic coating layer having a thickness in the range of 2 to 10 microns above the base substrate. A volume of 10 nl/mm2 or less of inkjet ink is used in order to image areas in which the image is solid. Further, areas of the top hydrophilic coating layer, which are imagewise covered by aqueous pigmented inkjet ink, become hydrophobic.

Abstract: Embodiments of the invention are directed to a method for preparing a printing member. The method may include selectively applying an imaging material onto the hydrophilic coating of a transfer media to form an image The transfer media include a heat-resistant layer and hydrophilic coating. The transfer media may further include a thermoplastic layer. The method may further include hot laminating the transfer media with a substrate having hydrophilic surface and separating the substrate and the transfer media such that at least the image is transferred onto the hydrophilic surface of the substrate.

Abstract: A method for coating two substrates, face to face (F2F), simultaneously, by laminating the two substances while encapsulating coating material as a thin film in between the first substrate and the second substrate. Then the coated material is conditioned into solid or partial solid layer. Later the two substrates are separated for creating two coated substrates the first coated substrate and the second coated substrate.

Abstract: According to embodiments of the present invention, a method for manufacturing an imaged printing member is provided. The method may include imaging a selected image onto a transfer media which is coated with a surface forming coating by applying an image carry material onto the transfer media. Then, applying a coating material onto the substrate and/or the imaged transfer media and laminating the imaged transfer media with the substrate such that the coating material is captured in between. Next, the method may include conditioning the coating material to form the imaging layer of the printing member, the imaging layer having imaged areas and non-imaged areas, wherein the top layer of the non-imaged areas is an interface area between the coating material and the surface forming material.

Abstract: Lithographic printing members and a method and system for fabricating them is provided. The printing member may comprise a base layer, a laser-absorbing layer, which may be a gradient solid dispersion of metal and metal-oxide areas, and a coating layer. The concentration ratios between the metal and the metal-oxide vary throughout a thickness of the laser-absorbing layer and the coating layer and the base layer have different affinities for ink. The method of fabricating the printing member may comprise preparing on demand for a single use a liquid-based coating material, pouring the coating material onto a substrate that may comprise a base layer and a laser-absorbing layer and laminating a form film onto the liquid-based coating material to form a coating layer.
