Abstract
A generally cylindrical image embossing tool which can be used for embossing a web of material in continuous manner is made by placing an image or pattern which is to be replicated onto an embossable material maintained in the form of a cylinder. An electroform in generally cylindrical form corresponding to the image or pattern to be replicated is formed from the imaged embossable material and the electroform is supported on a rigid cylindrical support to form the image transfer tool. A novel imaging tool has a curved stamping surface carrying an embossed image or pattern. The radius of curvature of the stamping surface matches the radius of curvature of a cylindrical surface which is to be stamped so as to transfer the image or pattern which is to be replicated.
