A process for manufacturing three-dimensionally shaped polymeric sheets and laminates with color-matched digitally printed full color ink jet images. A flexible thermoformable polymeric baseweb is placed in an ink jet printer and a solvent-based (non-aqueous) digital printing ink is applied directly to the baseweb, in the absence of an ink receptive layer on the baseweb, to form a decorative pattern in multiple colors in a single pass through the printer. The finished product can be thermoformed or injection molded to a three-dimensional shape. A protective topcoat can be laminated to the digitally printed sheet prior to the thermoforming and/or injection molding step. A process for making color-matched products comprises producing a software-driven image of a pattern on a screen representing a standard color print pattern; evaluating and adjusting the standard displayed on the screen using software-driven image related adjustments for hue, contrast, lightness/darkness, etc.; producing a test print by applying a decorative pattern to the baseweb by a digital ink jet printer and making an optional software-driven image-related adjustment in the standard to color match the standard to the test print image; and when the adjusted standard image displayed on the screen is acceptable, passing an image-related output to the digital ink jet printer for printing a decorative print color-matched to the accepted onscreen standard.

An optical imaging head for direct engraving of flexographic printing plates, comprising: at least two groups of radiation sources, each group comprising at least one radiation source, wherein the radiation sources within each group emit radiation having the same intensity and spot size, different from the intensity and spot size of radiation sources in the other groups, said groups of radiation sources operating simultaneously.

The invention relates to a method for producing flexographic printing forms by engraving a printing relief on a flexographic printing element that can be laser engraved, said element having a photochemically cross-linked relief layer. The relief layer is transparent and comprises oxidic, siliceous or zeolitic solid matter with a particle size between 1 and 400 nm in a quantity of between 0.1 and 8 wt. % in relation to the quantity of all components in the relief layer.

An integrated, in-line bumping and exposure system for printing plates or other substrates having a photosensitive layer. A linear illumination source or sources are for bumping the photosensitive material with a band of illumination to consume dissolved oxygen within the photosensitive layer. A raster scan optical assembly or an illuminated and re-imaged spatial light modulator array exposes the photosensitive material with a rasterized beam or beams or an array of modulated electromagnetic radiation located downstream of the bumping illumination. A conveyance mechanism is configured to provide relative continuous motion between one or more substrates and the bands of illumination to continuously bump and pattern one portion of the plate or plates while the other portion of the plate or plates is bumped in anticipation of patterning.

An improved apparatus for thermally developing a flexographic printing element to reveal a relief image on the surface and a method of using the apparatus to expose and develop a flexographic printing element. The apparatus typically comprises means for softening or melting non-crosslinked photopolymer on the imaged and exposed surface of the flexographic printing element; at least one roll that is contactable with the imaged surface of the flexographic printing element and capable of moving over at least a portion of the imaged surface of the flexographic printing element to remove the softened or melted non-crosslinked photopolymer on the imaged and exposed surface of the flexographic printing element; and means for maintaining contact between the at least one roll and the imaged and exposed surface of the flexographic printing element. The means for softening or melting non-crosslinked photopolymer on the imaged and exposed surface of the flexographic printing element comprise a heater positioned adjacent to the imaged surface of the flexographic printing element and/or heating the at least one roll that contactable with the imaged surface of the flexographic printing element. The apparatus may also contain an exposure device to crosslink and cure the imaged surface of the flexographic printing element prior to thermal development.

In this method for producing an anti-reflective film, pores are formed on a surface of a polymer molding material to continuously change a refractive index and then reduce reflectance, in which anodic oxidized porous alumina, in which pores having a tapered shape and whose pore diameter continuously changes, are formed by repeating anodic oxidation at about the same formation voltage and pore diameter enlargement treatment, is used as a mold, or a stamper, which is produced by using the anodic oxidized porous aluminum as a mold, is used as a mold.

An imaging member includes a surface layer comprising a fluoroelastomer-perfluoropolyether composite formed from a reaction mixture comprising a fluoroelastomer and a perfluoropolyether compound. Methods of manufacturing the imaging member and processes for variable lithographic printing using the imaging member are also disclosed.

Molded structures, methods of and apparatus for producing the molded structures are provided. At least a portion of the surface features for the molds are formed from multilayer electrochemically fabricated structures (e.g. fabricated by the EFAB™ formation process), and typically contain features having resolutions within the 1 to 100 μm range. The layered structure is combined with other mold components, as necessary, and a molding material is injected into the mold and hardened. The layered structure is removed (e.g. by etching) along with any other mold components to yield the molded article. In some embodiments portions of the layered structure remain in the molded article and in other embodiments an additional molding material is added after a partial or complete removal of the layered structure.

A clean running flexographic relief image printing element and a method of making the same is described. The relief image printing element comprises (a) a backing layer; (b) a floor layer disposed on the backing layer and comprising a photopolymer containing a silicone monomer or silicone oil, wherein the cured floor layer has a surface energy of between about 18 to about 25 dynes/cm; (c) a cap layer disposed on the floor layer and comprising a photocurable composition that is capable of being imagewise exposed to actinic radiation to create a relief image therein, wherein the cap layer has a surface energy of between about 30 and about 40 dynes/cm; and (d) a removable cover sheet. The differential of surface energies between the floor layer and the cap layer increases how clean the plate will print over time.

A hollow cylindrical printing element, comprising a hollow cylindrical core material (A) and a resin layer (B) or a resin layer (C). The hollow cylindrical core material (A) further comprises a photosensitive resin hardened layer (1) of 0.05 to 50 mm in thickness having a fiber-like, cloth-like, or film-like reinforcement material and the shore hardness D of 30 to 100°. The resin layer (B) is laminated on the hollow cylindrical core material (A), has a thickness of 0.1 to 100 mm, and allows a pattern to be formed on the surface thereof. The resin layer (C) has a pattern formed on the surface thereof.

A lithographic printing plate precursor which is capable of undergoing on-press development by supplying at least one of printing ink and dampening water and includes a support and an image-recording layer, wherein the image-recording layer contains at least one of compounds represented by the formulae (1) to (3) as defined herein.
