METHOD FOR THE IMPLEMENTATION OF OLOGRAMS ON LAMINATES OF ALLUMINUM LEGISLATION AND OTHER

摘要

A method for creating holograms on surfaces of aluminium alloys and similar, lacquered and adhesive-bonded products, comprising the steps of: performing a holographic recording of a subject on a glass support rendered photosensitive by the application of a photoresist; developing holographic recording; silvering said developed support; depositing on said developed support a layer of nickel by means of galvanic bath to form a first nickel plate with said subject in negative; obtaining, from said first nickel plate with said holographic recording in negative, a plurality of second nickel plates with said holographic recording in positive, by means of galvanic bath; creating a stamp arranging said plurality of second plates on said stamp in rows and columns; creating a holographic print matrix pressing said stamp on a PMMA or PET sheet; silvering said print matrix; creating a mother print plate in nickel from said print matrix by means of galvanic bath; said mother print plate having a greater thickness on two edges with respect to the centre of said mother print plate; creating copies and copies of said copies of said mother print plate with said holographic recording respectively in negative and in positive in nickel, by means of galvanic bath; using said copies of said copies of said mother print plate to print by engraving by means of an embosser said holographic recording on said surfaces of aluminium alloys and similar, lacquered and adhesive-bonded products.
