Abstract
A method of making a die and the die itself for establishing through embossing or micro-embossing a seamless pattern, preferably a holographic pattern, on a decorative medium such as a metallized film is provided. A cylindrical embossing or micro-embossing die is provided with a layer of an embossable material, preferably pure silver, a silver alloy or any other suitable embossable material. The cylindrical die is an integral member in which a pattern is recombined thereon by a step and repeat embossing or micro-embossing process as opposed an intricate lathe-type machine-turning operation, and can thus accept, carry and maintain complex patterns with the integrity required for producing a repeating holographic pattern.
Claims32
A method of making a die for embossing a seamless pattern onto a web of material, said method comprising the steps of:
- providing a die having a curved outer surface;
- coating said curved outer surface of said die with at least one layer of embossable material;
- mounting a stamping shim to a concave-shaped stamping surface of a stamp, said stamping shim conforming to said concave-shaped stamping surface of said stamp and presenting an embossing pattern;
- and
- impressing said embossing pattern of said stamping shim against a portion of said at least one layer of embossable material to form an embossment therein.
