Abstract: The invention pertains to a photosensitive element, particularly a photopolymerizable printing form precursor; a method of preparing the photosensitive element to form a printing form for use in relief printing; and, a process of making the photosensitive element. The printing form precursor includes a layer of a photosensitive composition, a digital layer that is adjacent to a side of the photosensitive layer, and a cell pattern layer that is disposed between the photosensitive layer and the digital layer. The cell pattern layer includes a plurality of features in which each feature an area between 5 to 750 square microns and is composed of an ink that is opaque to actinic radiation and transparent to infrared radiation. Since the cell pattern layer is integral with the printing form precursor, digital imaging can occur rapidly with relatively low resolution optics to form a mask without needing to also form a microcell pattern of the digital layer.

Abstract: The present invention concerns a chemical mechanical polishing pad having a polishing layer. The polishing layer contains an extruded sheet. The extruded sheet is prepared by extruding a compounded photopolymerizable composition followed by exposure to UV light.

Abstract: 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.

Abstract: The invention provides a method and apparatus for mounting two or more cylindrically-shaped printing forms onto a cylindrically-shaped base. The base can be a print cylinder or an adapter mounted onto a print cylinder. The method and apparatus provide for positioning the two or more printing forms in register on the base. The two or more printing forms are axially oriented on the base using pressurized air as an air cushion between the base and the printing forms, positioned in a registration position, and engaged by a holding member to maintain the two or more printing forms in their respective registration position.

Abstract: The invention provides an extended print sleeve having a longitudinal axis and adapted to form a printing form having a circumferential seam with no printing surface disposed a distance D along said longitudinal axis from one end thereof, comprising: a first print element; and a second print element; wherein each print element comprises a separate cylindrically-shaped support having a photosensitive layer thereon and disposed at a fixed position along said longitudinal axis, and wherein said second print element has a length substantially equal to distance D.

Abstract: The invention relates to a process for preparing a flexographic printing plate from a photosensitive element having a photopolymerizable layer and a thermally removable layer on the photopolymerizable layer. The process includes imagewise exposing the photosensitive element and thermally treating the exposed element to form a relief suitable for use in flexographic printing. The thermally removable layer can be transparent or opaque to actinic radiation. The invention also relates to a photosensitive element for use in this process. The photosensitive element includes a photopolymerizable layer and at least one thermally removable layer having a filler and a binder, wherein the binder is less than 49% by weight, based on the total weight of the binder and filler.

Abstract: Holographic images are constructed in a recording material in accordance with a temporal interleaving technique in which a first set of images is constructed for a predetermined first imaging time with a predetermined first time gap being defined between each of the images. Thereafter, in accordance with a subsequent predetermined sequence a subsequent set of images is constructed into the same predetermined location. The image sets have at least one member in common. In one aspect all of the images are constructed into the same predetermined defined region of the holographic recording material (an angle hologram). In another aspect the predetermined defined region into which each of the images is constructed is separate from all other regions of the holographic recording material (a spatial hologram).
