20090136679 | EMBOSSING DEVICE, SUCH AS A CYLINDER OR A SLEEVE - An embossing device, such as a cylinder or a sleeve, includes on an outer peripheral surface an embossing raised and recessed pattern, to be reproduced on a deformable planar substrate. The cylinder or sleeve bears a photopolymer coating the outer surface which has the raised embossing pattern. | 05-28-2009 |
20100316957 | METHOD OF PRODUCING A RELIEF IMAGE ARRANGEMENT USABLE IN PARTICULAR IN THE FIELD OF FLEXOGRAPHY AND ARRANGEMENT PRODUCED ACCORDING TO THIS METHOD - The invention relates to a method of producing a relief image arrangement, usable especially in the fields of flexography, embossing and heliogravure, and comprising a base layer and a layer of photosensitive material fixed on the base layer. The method is of the type according to which an image is produced on the photosensitive layer by causing selective curing by irradiating the zones that are to be in relief with light of a predetermined wavelength. The method is characterized in that the image is produced in the form of a set of points to which a substantially pyramidal shape is given, widening out in the direction of the base layer ( | 12-16-2010 |

20120003588 | Method of Improving Print Performance in Flexographic Printing Plates - A method of making a relief image printing element from a photosensitive printing blank is provided. The method comprising the steps of: 1) providing a photosensitive printing blank comprising a backing layer, at least one layer of photoresin on top of the backing layer and a removable coversheet on top of the at least one layer of photoresin; 2) imaging the photosensitive printing blank through the removable coversheet using a laser to create a relief image therein; and 3) removing the removable coversheet. | 01-05-2012 |
20120129097 | Photopolymer Printing Plates with In Situ Non-Directional Floor Formed During Extrusion - A photocurable relief image printing element is provided. The relief image printing element comprises at least a backing layer and at least one photocurable layer on the backing layer. The photocurable layer comprises at least one binder, at least one ethylenically unsaturated monomer, at least one photoinitiator, and an effective amount of a syndiotactic 1,2-polybutadine. The presence of the syndiotactic 1,2-polybutadiene results in a photocurable layer that exhibits minimal cold flow and good storage stability. | 05-24-2012 |
20140308617 | Method for Improving Print Performance in Flexographic Printing Plates - A method of making a relief image printing element from a photosensitive printing blank is provided. The method comprising the steps of: | 10-16-2014 |

20140335456 | Method of Improving Print Performance in Flexographic Printing Plates - A method of tailoring the shape of a plurality of relief printing dots created in a photosensitive printing blank during a platemaking process including the steps of: (a) selectively exposing at least one photocurable layer to a source of actinic radiation to selectively crosslink and cure the at least one photocurable layer; and (b) developing the exposed at least one photocurable layer to reveal the relief image therein, said relief image comprising the plurality of relief printing dots. The source of actinic radiation comprises a source of UV light in the UV-A range and a source of light in the UV-C range. The at least one photocurable layer is simultaneously exposed to the source of UV light in the UV-A range and the source of UV light in the UV-C range to produce printing dots having at least one desired geometric characteristic. | 11-13-2014 |
