    摘要: A method of producing a photocured structure comprising a backing layer for coupling to a relief image printing plate or as an integral all-in-one structure comprising a backing layer and a relief image printing layer. The photocured structure may be formed using a continuous liquid interphase method or three-dimensional plating to selectively crosslink and cure a photocurable composition. The backing layer may comprise a lattice or series of openings of the lattice where the placement and density of the openings is controlled.

    摘要: A method of producing a relief image or mold from a liquid photopolymer resin, said method comprising the steps of: a) placing an image film onto an exposure glass; b) placing a cover film over the image film and drawing a vacuum c) placing substrate material on a bottom glass d) casting a liquid photopolymer resin layer onto the substrate material; d) laminating a flexible polyester sheet onto a backside of the liquid photopolymer resin layer as the liquid photopolymer resin layer is being cast onto the substrate material; and e) exposing the liquid photopolymer resin layer through the image film to selectively crosslink and cure the photopolymerizable resin layer and form a cured relief image, wherein said depth of the cured relief image is less than the height of the cast liquid photopolymerizable resin.

    摘要: A method of creating a custom relief image printing element from at least one raw photocurable material and at least one lamination layer supplied by a manufacturer is described. The manufacturer provides a menu of raw photocurable materials and a menu of lamination layers and wherein the customer selects at least one raw photocurable material from the menu of raw photocurable materials and selects at least one lamination layer from the menu of lamination layers. The method includes the steps of: a) laminating the selected at least one raw photocurable material to the selected at least one lamination layer at a customer's location to create a photocurable printing blank; and thereafter b) imagewise exposing the at least one photocurable printing blank to actinic radiation at the customer's location to crosslink and cure portions of the at least one photocurable material and create a relief image therein. A lamination system is also described.

    摘要: The present disclosure is directed to a system and method configured for curing non-reactive photopolymer collected by an absorbent blotting material during thermal processing of flexographic printing elements. Uncured non-reacted portions of the photopolymer are removed by contacting the one or more layers of photopolymer with the web of absorbent blotting material at an elevated temperature to soften or liquefy the uncured non-reacted portions of the one or more layers of photopolymer and absorb the softened or liquefied uncured non-reacted portions into the absorbent web of absorbent blotting material. The web of absorbent blotter material containing the absorbed softened or liquefied non-reacted portions of the photopolymer is exposed to actinic radiation from the one or more UV light sources to crosslink and cure the softened or liquefied non-reacted portions of the photopolymer.

    摘要: A method of producing a flexographic printing plate using a continuous liquid interphase is provided herein. This method allows for significantly reduced production times and fewer preparation steps compared to standard non-continuous techniques and results in less waste than typical methods for preparing flexographic printing plates. The printing plate provided by using continuous liquid interphase production results in a printing plate with desirable elastomeric elongation, desirable hardness, plate thickness in the range of 0.030 inches to 0.250 inches, and comprises printing dots with desirable characteristics.

    摘要: A method of producing a granulated product from photopolymer printing plate materials. The method includes the steps of (a) sorting the photopolymer printing plate materials based on an identifiable property, wherein the photopolymer printing plate materials comprise one or more photopolymer layers; (b) grinding the photopolymer printing plate materials to particles; and (c) screening the particles to remove particles above a certain size and create the granulated product.

    摘要: The present disclosure is directed to a thermal developing assembly that is configured to reduce (or eliminate) the reactivity of contaminants and/or unreacted photosensitive material associated with forming a relief image on a photosensitive printing element during thermal development. The thermal developing assembly is configured to reduce (or eliminate) the reactivity of a byproduct associated with forming a relief image on a photosensitive printing element, the byproduct including but not limited to, contaminants within vapors (e.g., fumes), contaminants within condensate, unreacted photosensitive material, and combinations thereof.
