Nickel hologram matrix without coating and coated by the thin diamond-like carbon film
|Application: protection of documents and products against fakes. Diamond-like carbon coatings are used for wear resistant protection of a holographic relief of nickel working matrixes from which copying of holographic production is made by a method of stamping. The method used is chemical vacuum deposition. The technology has been patented.
