Holograms, holographic seals and imprints are used more and more for the authorization of documents, declaring of authenticity of the products and also for sealing those parts of the products in which it is needed to see whether the openning was unauthorized. Holograms are becoming a very sought out and effective way of prevention from falsification and misuse of anything that can be protected by a hologram. The hologram defines the highest standard of security and adds the profesionality and originality to the product. Generally, there are many ways to produce the holographic picture and also different ways to use it, including original purpose to save the data on the optic carriers.Obviously not all expensive ways of producing the holograms, originated from the research in the laboratories, are used for the production of holograms, because it is not a technology used for saving the data. What is in common for all holograms is a high diversity of graphic output, which outclasses the options of classic printing in multiple ways. Thanks to this characteristics it is very hard to eventually falsify and it is also one of the necessary conditions for the holographic effect. Above all that, high diversity allows to put security signs on the hologram about which the user will not know and they will be controlable only by special appliances or maybe only in the lab. This is for example microtext or micrographics, which can be, in addition to your wish, produced the way that it will be only readable under the laser light.
All holograms that are used for above stated purposes are, in fact, made of a specific film with purposedly deformated surface. The picture itself is created thanks to the refraction and intereferentions according to exact calculations of microscopic deformations. A mask for these nicks is made according to records given by the customer, that means according to any graphical data. Even if the pattern for the hologram production is in 2D, the final picture can be seen as 3D thanks to specific characteristics of the holographic display. We are able to produce 3D holograms as well, but the pattern for that must be graphically more complicated. that is the reason why most of our customers prefer the holograms made from 2D pattern. For self-adhesive stickers you can choose from 2 types of films - silver or golden.
Apart from the methods of hologram production stated above there are few others technologies, but they need a more complicated way to prepare the produciton and higher costs for the seal produciton. If you are interested in other kinds of holograms, feel free to contact us!
Every one of the techniques stated above can apply to 2 types of self-adhesive medias: the first one is a very thin smooth film which has a metallic layer on its basal part - that can be golden or silver, it depend on your choice. The holographic picture carrier is that exact metallic layer that has a holographic motive burned into while produced. The film defines mechanical strength of the whole seal and it is also used as a protection of the holographic layer from mechanical damage. There is a layer of glue on its basal part, just as it is on every ordinary self-adhesive sticker. When you try to remove the seal from its place, it gets damaged. The measure of damage depends on the surface that it is sticked to. Basically, it is impossible to remove the hologram and stick it to another place without damaging it, you just have to make sure that the surface you are placing the hologram on, is not greasy. The second type of media is so called destructive Void evident film. This self-adhesive medium is produced the way that any attempt to remove the seal would be clearly seen right away. The stamp gets evidently damaged. The seal is not removable neither by heating the film e.g. by a hot-flue gun, as it is possible with other self-adhesive security stickers. When trying to remove it, part of the holographic layer disjoins from the film, another part stays sticked to the surface and another one to the film. That part which stays sticked to the film is given by a chosen pattern media. There are 4 types of media produced in advance, which leave a clearly readable text "VOID", "ORIGINAL" or "Cancelled" or a regular graphical motive similar to honeycombs and leave this text or motive on both the surface and the film after removing. This method is used in all places which need to be prevented from unauthorized entries to prohibited areas like the inner parts of electrical systems, sealed documents, boxes for transportation of valuable things, doors of baggage areas sealed with bigger seals, etc.
The size of particular self-adhesive stickers is not limited and will always be correspondent with your requests. Practically, it is always possible to produce holographic seals with diameter of 3mm to stick to the tops of the screws, just as it is possible to produce a hologram of a size A4. All stamps will be cut according to your requested sizes and will be delivered in sheets to size A4 or in rolls. They will be cut according to the shape you choose when designing a graphical project of the seal. Basically, it is possible to produce a seal of any size, you just need to keep in mind that you want them to be easily transported to the object you want to label. For this reason we recommend you choose from these shapes: a circle, an ellipse, an oval, a square or a rectangle, a square or a rectangle with round corners, triangle, n-angle and similar periodic formations.
If by facts stated above you have an idea of how should a proper holographic seal fulfilling your requirements look like, it is needed to create its digital pattern. If you have an option to use any of the vectorial graphical editors (we recommend Corel Draw) and you have enough experience for creating the pattern, you can send it to us directly with the vectorial data. Of course, it would be our pleasure to prepare a pattern ourselves, using your specifics. In case of simpler motives all that is needed is their description in words, with exact parameters, according to which we will email you a graphical projection, in some case more of them. After its correction and approbation of the final graphical projection it is possible to start the production of self-adhesive stickers right away. In case you need seals of a small size, we highly recommend to print these seals during the projection by a regular printer in its exact parameters. In many cases the amount of textual and graphical information exceeds the options of a small format a bit and the result of this is a very small area that is overfull with information easily readable only by a microscope. This fact is not visible enough mostly when your projection is shown at 24'' monitor in graphical editor.
Applying customer Holographic foil destructive or self-adhesive hologram labels destructive or disruptive element films I obtain the object, which is not possible by any conventional polygraphic methods successfully reproduce. If provided with a printed custom holograms, as well as printed matter that can not be faithfully reproduced. This is one of the major benefits to using hologram labels and stickers, which the list begins.
