Abstract:
The invention relates to a photosensitive printing element for the production of flexo printing plates for newspaper printing, comprising at lest one flexible metal support, an adhesive layer applied on said support, an organically developable, photopolymerizable layer, a transparent substrate layer and optionally a removable protective foil, wherein the total thickness of the flexo printing element measures 300 to 1000 mu m, the elastomer binding agent has an average weight MW of between 80 000 to 150 000 g/mol and a Shore A hardness of between 50 to 80, wherein the amount of softening agent ranges from 5 to 50 percent by weight in relation to the amount of all components of the photopolymerizable layer. The invention also relates to a method for the production of newspaper flexo printing plates by imagewise exposure of the flexo printing element to actinic light, development and drying at 105 to 160 DEG C.
Abstract:
Block copolymers containing block having pendant fluoro-containing groups and block having pendant hydrolyzable ester containing groups is developed at lower pressures and temperatures than random copolymers of the same monomers. Where the block with ester groups is from polymerization of 2-tetrahydropyranyl methacrylate and the block with pendant fluoro-containing groups is from polymerization of perfluoroalkyl methacrylate or semifluorinated alkyl methacrylate, resolution of sub 0.3 mu m features is enabled.
Abstract:
Patterned articles, such as RFID antennas, are made by subablation, a process comprising the steps of: A. providing a substrate having a coating, such as a metal or metal oxide, and an interface comprising the thin region where the coating and the substrate are closest to each other; B. exposing at least one part of the total area of the coating to a flux of electromagnetic energy, such as a focused excimer laser beam, sufficient to disrupt the interface but insufficient to ablate the coating; and C. removing the parts of the coating in registry with the portion of the interface area that was disrupted, by means such as ultrasonic agitation. The process has advantages over photo-resist processes in that there is no residual chemical resist left on the product and no undercutting of the pattern or image. It has advantages over laser ablation processes in that higher throughput is possible at the same energy level and there is no microscopic debris left on the product surface.
Abstract:
Provided is a media-fluid material set for use in preparing a waterless lithographic printing plate. The media fluid material set comprises a media with a support that bears a hydrophilic receiving surface having ink-receiving properties, together with a fluid material comprising a liquid carrier medium and a reactive transition metal complex of a fluorinated organic acid. After an application of the fluid material to the hydrophilic recieving surface, the reactive complex reacts to form a durable ink-releasing layer. Such a media-fluid material set can be advantageously used in preparing waterless lithographic printing plates with ink-releasing layers comprising such fluorinated reaction products. Also provided are imaged waterless lithographic printing plates with such ink-releasing layers made by an ink jet printing application or by laser-induced thermal ablation, and methods of making such waterless lithographic printing plates.
Abstract:
Methods for fabricating nano-structured surfaces having geometries in which the passage of elementary particles through a potential barrier is enhanced are described. The methods use combinations of electron beam lithography, lift-off, and rolling, imprinting or stamping processes.

Abstract:
A method comprising providing a carbonaceous material, the substrate having a first thermal conductivity. The method further comprises depositing a first masking layer having a second thermal conductivity on at least a portion of the substrate, a ratio of the second thermal conductivity to the first thermal conductivity being less than or equal to 1:30. The method further comprises depositing a second masking layer on the first masking layer to form an etch mask, and etching an exposed portion of the substrate.
Abstract:
A method of operating a manufacturing platform includes moving a substrate through the manufacturing platform using one or more transfer modules. A dry resist is deposited on the substrate using a resist deposition module of the manufacturing platform. The substrate is examined for distortion with a metrology system that is part of a transfer module. The dry resist is exposed to UV or EUV radiation using an exposure tool of the manufacturing platform. Exposed or unexposed portions of the dry resist are removed using an etch module of the manufacturing platform.
