Security hologram
Security holograms are labels with a hologram printed onto it for sale security reasons.
It is argued by the International Hologram Manufacturers Association that holograms on security labels are difficult to forge because they are replicated from a master hologram which requires expensive specialized and technologically advanced equipment. However, security holograms have also been criticised for their ineffectiveness, because equipment for manufacturing holograms has become significantly easier to access, and because few people have the expertise and equipment to authenticate them accurately.
Security holograms are used widely in several banknotes around the world, in particular those that are of high denominations. They are also used in passports, credit and bank cards as well as quality products.
Holograms are classified into different types with reference to the degree of level of optical security incorporated in them during the process of master origination. The different classifications are described below:
These are by far the most common type of hologram – and in fact they are not holograms in any true sense of the words.[citation needed] The term "hologram" has taken on a secondary meaning due to the widespread use of a multi-layer image on credit cards and driver licenses. This type of "hologram" consists of two or more images stacked in such a way that each is alternately visible depending upon the angle of perspective of the viewer. The technology here is similar to the technology used for the past 50 years to make red safety night reflectors for bicycles, trucks, and cars.[citation needed]
These holograms (and therefore the artwork of these holograms) may be of two layers (i.e. with a background and a foreground) or three layers (with a background, a middle ground and a foreground). In the case of the two-layer holograms, the matter of the middle ground is usually superimposed over the matter of the background of the hologram. These holograms display a unique multilevel, multi-color effect. These images have one or two levels of flat graphics “floating” above or at the surface of the hologram. The matter in the background appears to be under or behind the hologram, giving the illusion of depth.
These holograms have a maximum resolution of 10 micrometers per optical element and are produced on specialized machines making forgery difficult and expensive.[citation needed] To design optical elements, several algorithms are used to shape scattered radiation patterns.
Flip-flop hologram master origination is a technique used to produce holograms that display flip-flop effect.[jargon] They are produced with a 2D/3D master shooting system. This two channel effect of 2D/3D holograms displays two different images from different angles. These holograms are often fabricated using supreme quality material.[citation needed] The final master obtained from this flip-flop mastering technique are used to manufacture holograms which gives flip-flop effects. Having an excellent blend of 2D/3D and flipping images offers holographic images an excellent depth and a dazzling appeal.[promotion?]
