  • METHOD OF PRODUCING A RELIEF IMAGE ARRANGEMENT USABLE IN PARTICULAR IN THE FIELD OF FLEXOGRAPHY AND ARRANGEMENT PRODUCED ACCORDING TO THIS METHOD
    Publication number: 20100316957
    Abstract: 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 (5). The invention is usable for producing relief images, in the field of flexography.
