2D-3D-holograms
It is a multiplayer holographic image where each element (layer) is located at some distance from each other. Such holograms comprise a set of protective elements and thus they are used for protection of goods, documents and securities. (a waybill photo, a license)
3D-holograms
3D-holograms are created from a real object and they represent its exact spatial copy. They are widely used for advertising purposes, for trade marks image creation and for identification problems solutions.
Image-matrix holograms
This type of holograms is based on computer graphics that allows to create bright contrast holograms with kinetic effects. Though an image consists of separate areas, there can be included a great number of elements into a hologram, verifying product’s authenticity.
Combined holograms
A combined hologram- is a hologram, that consists of the elements that are recorded by different methods, digital and analogue, combined with high accuracy. The process of combining of different images and holographic effects is very sensitive to any microscopic changes in these structures it leads to distortion of coded information. These peculiarities exclude the possibility to fake the hologram. The elements are identified with the help of special means made according to the requirements these protective structures of decoding.
Unigram
A unigram is a hologram with a latent image which is shown by means of a simple identifier.
The control of authenticity:
Visual with naked eye;
Visual by means of latent image identifier;
Laboratory methods of authenticity assessment by means of special equipment.
Types of holograms according to foil characteristic:
1) nondestructive labels. If such label will be attempted to be reapplied the image will remain in its base. You can transfer these labels to another object.
2) partially destructive. When tried to be reapplied some part of the image remains on the substrate, the other part on the object. These labels are impossible to transfer to another product.
3) fully destructive. When tried to be reapplied the image remains on the object, the substrate is fully separated. These label are impossible to transfer to another object.
