Energy curable compositions comprising polyols, and any blend of ethylenically unsaturated monomers and oligomers. The polyols of the invention are essentially free of any ethylenically unsaturated groups. It is preferred that the polyol substances according to the invention have greater than one hydroxy group and preferably have boiling points in excess of 170 C. The compositions of the invention are particularly useful for the printing or coating of food packaging and may be applied via any printing or coating method, although inkjet printing is a preferred method.

An optical fiber ribbon manufacturing device includes: fiber-supplying units that respectively supply optical fibers; a printing device that prints a mark on each of the optical fibers; and a ribbon-forming device that manufactures an optical fiber ribbon by connecting the optical fibers on each of which the mark has been printed. The printing device includes: a supplying roller that supplies an ink; and a printing roller that includes a printing pattern on a surface thereof and that prints the mark on each of the optical fibers that are lined up in a width direction of the optical fibers by causing the ink supplied from the supplying roller to adhere to the printing pattern and transferring the ink onto the optical fibers. Projections and depressions are disposed on a surface of the supplying roller. The surface of the supplying roller opposes the printing pattern of the printing roller.

A method to manufacture an article comprises applying an ink to a substrate. The ink includes a liquid vehicle, a plurality of solid metal particles, a plurality of gallium-containing particles, and a thermally activated flux. The method further comprises curing the ink by heating the substrate to within an activation temperature range of the flux. The article manufactured by this method comprises a substrate, an electronically conductive film arranged on the substrate, and an adherent barrier layer covering both the substrate and the film. The film includes a plurality of solid metal particles with a gallium-based liquid metal bridging the plurality of solid metal particles.

A process for producing tactile and sealing features on flexible films 40. The temperature of resin 80 is raised until it melts, but below its flash point. Wetting hot roll cylinder 10 with the resin 80 in negative cells 14 and transferring to positive textures 24 in cylinder 20. Transferring part of the thermo resin 80 on cylinder 20 to coacting cylinder 30 and passing a continuous flexible film 40 through coacting hot cylinder 20 and cold cylinder 30. The control of the temperature differential between cylinder 20 and film 40 allows the maximum transfer of resin 80 to form tactile structures. Sealable print areas are also created in film 40 that are particularly useful for packaging applications.

There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface with a monolayer of particles, ii) treating the substrate surface to render at least selected regions tacky, and iii) contacting the substrate surface with the donor surface to cause particles to transfer from the donor surface only to the tacky regions of the substrate surface. After printing on a substrate, the donor surface returns to the coating station where the continuity of the monolayer is restored by recovering with fresh particles the regions of the donor surface exposed by the transfer of particles to the substrate.

The present invention relates to a printing form for flexographic printing. The printing form contains microcell patterns on its relief printing surface. The presence of these microcell patterns allows for printing with a higher anilox roll volume. Also disclosed are five specific microcell patterns.
