Abstract: The present invention is directed to the manufacture of "seamless" photosensitive printing elements from substantially planar printing plate blanks wrapped around cylindrical printing sleeves or carriers. The method comprises the steps of cutting a photosensitive printing element to a size for wrapping around a printing sleeve, trimming ends of the photosensitive printing element to create a gap when the printing element is wrapped around the printing sleeve, attaching the photosensitive printing element to the printing sleeve and filling the gap between the ends of the photosensitive printing element with a filler material.

Abstract: An automated method of preventing edge curing of cut surfaces of photosensitive printing elements is disclosed. Once a photosensitive printing element is cut in a pattern of a desired size and shape, a portion of the coversheet on a periphery of the cut edges of the printing plate is removed, while leaving intact the layer of photocurable material and the optional ablation layer beneath the coversheet. Next, an edge cure prevention composition is applied to the optional ablation layer or the layer of photocurable material revealed by the removal of the portion of the coversheet. Once the edge cure prevention composition is dried, the remainder of the coversheet may be removed from the photosensitive printing element and the printing element may be mounted on a sleeve or cylindrical carrier for further processing. The method ensures that the edge cure prevention composition is applied only to areas where it is needed and does not affect imageable areas of the printing plate.

Abstract: An improved method of manufacturing a photosensitive printing element that minimizes relief variation and improves image fidelity. The method involves a step of pre-curing the first (floor layer) of photocurable material prior to depositing an additional layer or layers of photocurable material that may be imaged and developed to produce a desired relief image on the surface of the photosensitive printing element. The photosensitive printing element is then thermally developed by contacting the photosensitive printing element with at least one roll that is 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. Non-crosslinked photopolymer on the imaged and exposed surface of the flexographic printing element can be softened or melted by positioning a heater 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.

Abstract: An inkjet printer is used to apply an ink that is substantially opaque to actinic radiation in at least one wavelength region effective to cure the photosensitive printing plate to the edges and corners, of a printing plate after the plate has been trimmed (i.e., cut) to a suitable size and shape for mounting on a printing sleeve or cylinder. Use of inkjet printing allows for the cut surfaces of the plate to quickly and accurately be coated with a UV-opaque ink and prevents, or substantially eliminates, undesirable curing of cut surfaces of a photosensitive printing plate. The ink covers the photocurable surfaces exposed by the cutting process and prevents the cut surfaces of the printing plate from undesirably curing until proper exposure and development of the printing plate.

Abstract: Laser imageable flexographic printing elements, including printing plates and printing sleeves and methods of making the laser imageable flexographic printing elements using a collapsible cross-linkable material comprising a curable elastomer, a material that absorbs laser radiation at a selected wavelength, and microspheres are disclosed. A laser is used to collapse and melt the collapsible cross-linkable material to form a relief image on the printing element. The printing element is thereafter cured by face exposure to crosslink and cure the formed relief image. The invention addresses a market need for eliminating chemical processing of printing elements, thus going from printing element to press much more quickly and using an environmentally friendly process.
