Abstract
The invention concerns a method for making safety labels which consists in producing a base deposit on the film (100), then in defining a label shape (101). It further consists in producing (102) a printed window preferably by photogravure with cells bordered by a stripe forming the window outline; printing (103) the printing window on the base deposit with a passivation coating, and developing the window (104) by a physico-chemical operation.
Claims54
A method for making safety labels intended to be fixed on products to be protected against falsifications or to be integrated therein by the authentication and security of long-series printed circuits, comprising the steps of:
- making abase deposit on a film,
- defining a label shape,
- making a printing window on a printing form comprising an engraved surface with cells bordered by a stripe forming the outline of the window, geometries, and letterings,
- parting the printing window with making on a film base deposit with a passivation coating,
- developing the window by a physico-chemical operation,
- detaching and recovering the label to use it as it stands or to transfer it to the surface and/or core of the security and authentication material.
A security label intended to be fixed on products to be protected against falsification or to be integrated therein, comprising a film incorporating multiple layers of insulating and conductive materials or insulating and metallic materials able to be used in the printing of fiduciary materials in order to make them secure, and wherein:
- a base deposit is made on the film;
- a label shape is defined;
- a printing window, made according to the label shape on a printing form comprising an engraved surface with cells bordered by a stripe forming the outline of the window, geometries, and letterings, is printed on the base deposit in a passivation coating;
- the window is developed by a physico-chemical operation;
- and
- the label is detached and recovered to use it as it stands or to transfer it to the surface or core of a material for security or authentication.
A label according to clam 38 intended to produce holograms or devices composed of optically variable or diffracting images or images optically variable by diffraction for security purposes that are marked and demetallized, wherein the thickness of the passivation coating is between 0.5 and 8 μm.
