  • Patent number: 8796583
    Abstract: A structured surface is formed with the method of the present invention. The method of making this structured surface includes the steps of applying an ablatable radiation sensitive coating on the major surface of the substrate, and exposing the ablatable radiation sensitive coating to radiation such that exposed portions of the ablatable radiation sensitive coating ablate from the substrate to form a structured surface. The structured surface then includes a substrate and a pattern of structures framed by at least one separation bank. The method may also include the steps of depositing a flowable material on to the structures and the separation bank to form a pattern of flowable material in the structures.

  • Patent number: 8632944
    Abstract: A mask-forming film has a transparent layer between the imageable layer and the carrier sheet, which transparent layer has a refractive index that is lower (by at least 0.04) than that of the carrier sheet or any immediately adjacent layer between it and the carrier sheet. This lower refractive index layer modifies the path of incident radiation during mask image transfer so as to provide steeper shoulder angles in the relief image solid areas. This mask film is used to form a relief image such as in a flexographic printing plate.

  • Publication number: 20130319275
    Abstract: A method for providing a pattern, such as printed lines, is carried out by applying ink to a surface of a substrate. The ink and substrate are chosen such that the such that the polarity (?P/?D)1/2 of the substrate surface is less than or equal to 0.6 and the difference in polarity of the substrate surface and the ink [?(Polarity)] is less than or equal to 0.1. The result is higher resolution in the printed pattern such as higher resolution in printed lines.

  • Patent number: 8530117
    Abstract: The present invention involves a method for making a relief image. A film that includes a carrier sheet and an imageable material is used to form a mask image that is opaque to a curing radiation. In one embodiment, the mask image is formed on the carrier sheet while in another embodiment, the mask image is formed on a receptor sheet. The mask image is then transferred to a photosensitive material, such as a flexographic printing plate precursor. The resulting assembly is exposed to the curing radiation resulting in exposed and unexposed areas of the photosensitive material. The carrier sheet or the receptor sheet may be removed from the mask image either before or after exposure to the curing radiation. Finally, the photosensitive material and mask image assembly is developed with a suitable developer to form a relief image.

  • Patent number: 7317577
    Abstract: An opaque matrix that defines transparent apertures may be formed on a lenticular lens by applying an infrared radiation sensitive material to the flat surface of the lenticular lens, projecting infrared radiation through the lenticular lens onto the infrared radiation sensitive material to create exposed and unexposed areas of the infrared radiation sensitive material, and removing the exposed areas of the infrared radiation sensitive material from the flat surface of the lenticular lens. The infrared radiation sensitive material includes an infrared absorbing dye and a colorant. The infrared radiation sensitive material may also include a binder. A barrier layer may be disposed between the flat surface of the lenticular lens and the infrared radiation sensitive material. The barrier layer may include a binder, an infrared absorbing dye, and a crosslinking agent. The resulting lenticular lens may be used in a rear projection television screen or monitor.

  • Publication number: 20060127805
    Abstract: A kit for making a relief image that includes a film made of an infrared-imageable material and a separate imageable article comprising a photosensitive material disposed on a substrate. The film may be used to form a mask image that is opaque to a curing radiation by exposing the infrared-imageable material to infrared radiation. The mask image may then be transferred to the photosensitive material. The resulting assembly may be exposed to the curing radiation resulting in exposed and unexposed areas of the photosensitive material. Finally, the photosensitive material and mask image may be developed with a suitable developer to form a relief image.
