Production of holograms to order. Holographic Paper (Foil) Method of making colored holographic paper

Holography is one of the best ways to protect against counterfeiting. In addition, this type of protection is the most economical and effective. Today, holography is used by authorities as the most reliable method of protection against counterfeiting of important securities. The shiny label can be seen on passports, banknotes, visas and other securities that require a high degree of protection.

Recently, protecting products from counterfeiting has become important for manufacturers of quality goods. Such a need arose due to the fact that counterfeits of products that, due to their high quality, have already proven themselves among buyers, are increasingly appearing on the market. In order to prevent the appearance of counterfeits, honest manufacturers resort to various methods, including changing packaging, printing and much more. However, according to statistics, such innovations can also be used by attackers. That is why more and more honest manufacturers are seeking to secure their products using a hologram. Today, holographic packaging, which can be made of paper or polymers, is becoming increasingly popular. Holographic paper is ideal for making labels for glass and plastic bottles. Such a label performs several functions at once. Firstly, it reliably protects products from counterfeiting, and secondly, it attracts the attention of buyers with its original appearance. The bright hologram is becoming more and more popular every day all over the world. So what is hidden under the name “hologram”?

From the Greek, the word “hologram” is translated as “complete record.” This means that such a label contains extensive information about the item. Holography began to develop after the invention of the laser, which is a source of coherent radiation. A hologram is the display of a micro-relief image on a photosensitive material due to the registration of a wave field. After light hits the microrelief, diffraction occurs. This phenomenon causes the hologram to shimmer and shine, which is why holograms are called iridescent. The method of printing holograms is based on the interference of light. The elements in the hologram are equal in length to the laser radiation wave. If you recalculate the number of dots per inch, it will be 1500 dpi. No printing machine can achieve such a resolution. That is why holograms are considered to be the most reliable way to protect against counterfeits. The most popular are holograms in the form of self-adhesive labels. Such labels are applied to products manually or using special equipment. A self-adhesive hologram consists of several layers of films, which is why such a sticker cannot be pasted onto a fake.

For reliable protection documents, securities, exclusive products are usually used holographic foil for hot stamping. It contains all the necessary information about the object. In this case, application is carried out using hot stamping equipment - a manual press or an automatic printing machine.

For hot stamping, a special type of foil is used - holographic scratch. The surface of such foil can be easily removed, and hidden information can be discovered underneath it. This foil is commonly used on lottery tickets.

The choice of one type of holography or another depends on the scope of application. Based on recording methods, rainbow holograms are divided into two types - 2D and 3D.

The first type has areas with different color effects. If you look at the hologram from a different angle, you can see a consistent change in color.

The 3D hologram uses iridescent volumetric plans. If you rotate such a hologram, the plans will shift. Essentially, a 3D hologram displays a real object. Such holograms are usually printed on a metalized polymer base.

If we talk about the method of applying a hologram, then the image is obtained by using different principles than when printing photographs or replicating copies. Hologram printing is a kind of recording of information in different ranges, which allows you to hide the necessary information, which is almost impossible to decipher. Depending on how important the use of the hologram is, its complexity is determined. In order to increase the degree of protection, special hidden images, various microfonts, numbering and other effects are used. In addition to visual protection, hardware technology can also be used. With this method, special elements are introduced that can only be recognized when using special equipment.

Holography is a relatively young technology. However, at the moment it is actively developing. Methods for producing holograms are constantly being improved.

In addition, recently holograms, which are applied directly to product packaging, have become increasingly popular. Thus, a new direction has emerged - packaging using holographic elements. Any material used for packaging can be used to apply a hologram. Such packaging can contain all the necessary information, both hidden and explicit. Having a hygiene certificate allows you to use holography even on food packaging. Holographic images can be printed using any available method. The use of holographic packaging makes it possible to achieve high economic indicators. Since a product in bright and iridescent packaging attracts more attention from buyers, it becomes more recognizable and in demand, in contrast to the same products in regular packaging. Holographic packaging shimmers with all the colors of the rainbow and attracts attention due to the principle of light reflection, which is reflected from such a surface more than from ordinary paper.

The use of modern technologies in the production of holographic packaging opens up new opportunities. Because such a product has a number of advantages. As mentioned above, due to their original appearance, they attract the attention of buyers. In addition, such packaging provides reliable protection of the product from counterfeiting.

Made according to your design. It is a fairly reliable type of protection against counterfeiting and product quality control or protection against opening the packaging. A colorful hologram is an element of the company’s image, which gives the status of the company and the product itself.

From us you can buy holograms, both ready-made and custom-made. To produce individual holograms, you need to produce a matrix, the price of which is about 45-60 thousand rubles.

A cheaper replacement for the hologram is the pseudo-hologram.

Production time is approximately 10-15 days. Urgent production of holograms is possible within 7 days, the price will be higher.

Description of the hologram as protection against counterfeiting

When ordering the production of holograms from us, your customers will learn about the quality of the product, now it will not be so easy to fake it! You can order ready-to-use holograms in the form of a protective self-adhesive label, which leaves marks on the surface when removed. It will no longer be possible to stick it back. They are applied as a sign of protection against counterfeiting (genuineness of goods), when marking products as warranty stickers, to protect any type of packaging from illegal opening - these are self-destructive sealing stickers.

The superimposed patterns give a magnificent optical effect, the creation of which requires a complex set of technologies (holographic foil, laser, certain materials and matrices). Its fake is almost impossible. One of the security elements is Microtext, hidden signs.

Shapes and sizes of holograms (as an example)

Additional protection in holograms

The microtext font size ranges from 1 mm, when the text can be distinguished with the naked eye, to 0.1 mm, when the text is visible only with a magnifying glass. Plus, it can be manufactured with optical differences, or produce a whole series of hidden signs(which only you and I will know about), which significantly increase the security of the protective hologram - hidden information. These distinctive features are introduced into the hologram during its manufacturing process and are read by special devices using UV, IR or laser beams.

Additionally, standard and exclusive holograms can be numbered, either hidden, under the scratch surface (the erasable surface of lottery tickets), or explicit. Depending on your wishes, such a label may have a base that can be destroyed when you try to remove it ( self-destructing holograms) or non-destructible base ( holograms on mylar base).

The choice of material for a hologram depends on its functions

To produce protective holograms, we we use destructible bases, if you try to remove a hologram from the surface, it is mechanically destroyed according to the algorithm characteristic of this material (shell, peeling, image rupture). Can be used as an expensive warranty seal for expensive goods, etc. Another option is indestructible foil, which peels off easily and leaves no marks. Each specific type requires elaboration together with the Client when ordering.

It is possible when applying a logo, company name and other unique elements to a ready-made standard background. The application of an inscription or design can be carried out using the method of stamping from colored foil, when a single-color image is printed on the finished hologram. You can also make laser marking, in which the background layer is burned out and the inscription becomes transparent. Individual numbers can be applied to holograms, which enhances protection and product accounting.

Stages and equipment for making holograms

The first stage of making a hologram is shooting a model. It can be performed using different technologies: optical and digital. Optical technology is the process of capturing a three-dimensional object on a holographic plate. Additional flat images and texts are applied during re-exposure through pre-prepared masks. A master hologram is obtained, which is transferred to a glass plate coated with chromium and photoresist using the contact copying method. The microrelief is formed after etching the photoresist. For this method, a stand for holographic photography, baths, reagents, and a spray chamber are used. Digital technology begins with the calculation of the holographic structure on a computer. After this, it is displayed on a chromium layer using microphotolithography using a special laser or electron beam machine.

The second stage of hologram production is the creation of a master matrix. Serial prints can be produced using thermal printing. In this case, the microrelief is transferred from the surface of chromium to the surface of nickel foil, which is characterized by thermochemical resistance, hardness, and elasticity.

The third stage is printing. It is produced on a rolling machine that clamps the master foil with heated rollers. Under high pressure, foil and lavsan film are rolled along the shaft.

The fourth stage is sizing. To do this, a special adhesive application machine is used, which applies protective paper and glue to the back surface of the tape.

The fifth stage is cutting out holograms. For this, an automatic or manual cutting machine or a laser cutting machine can be used (for complex hologram contours). The sixth stage is numbering using a laser machine. In addition to industrial production, it is possible to produce holograms at home. Of course, the quality of such a hologram will not be very high, but expensive special equipment will not be required.

Production of original holograms with protective properties

Each hologram can be equipped with a number of unique decorative and protective properties. Decorative and protective properties of original holograms:

Modern trends in the field of holographic protection technologies are aimed at using combined methods and means of protection, and the farther the protective elements (methods) are technologically separated from each other, the more difficult the task for the future attacker. Based on this concept, we can formulate certain requirements for the level (degree) of security:

the level of security of the hologram must correspond to its purpose (a high level for more responsible use of the tag);

degrees of holographic protection must be carried out using different technologies so that they cannot be reproduced within the framework of the conventional holographic process;

identification of the authenticity of a hologram must be a multi-stage procedure in which each of the observers identifies its own security element or group of elements;

the set of protective elements should include: degrees of protection recognizable to an uninformed observer at the level of impression; degrees of protection designed for different levels of observer awareness, as well as degrees of protection with automatic identification independent of the qualifications and awareness of the observer.

Depending on the manufacturing technologies used, holograms are divided into:

physical,

multiplex,

synthesized .

During production physical holograms use a natural object.

Receipt multiplex holograms based on the technology of multi-angle shooting of physical holograms.

Synthesized holograms - this is the result of mathematical calculations of the holographic field and its direct drawing in one way or another on the appropriate medium. In rainbow holograms, the image is due to the frequency and angular orientation of diffraction gratings. These gratings can be created by direct drawing with a focused electron or optical beam. There are special installations for this, for example, an electron beam lithograph. Recently, installations have become widespread that make it possible to obtain rainbow images consisting of a large number of dots, 10-15 microns in size. Each point represents a simple diffraction grating.

The combination of the above methods of recording pictures in one image is called combined .

There is another classification of holograms according to the method of their production. It includes three types:

analog - during production an optical table is used (a large metal plate that is mounted on special balancing elements to achieve maximum accuracy in creating an optical circuit for recording) and a corresponding laser.

electronic - a holographic image is recorded on a matrix using an electron beam using a pre-compiled computer program (by the way, multiplex holograms are one of the results of the electronic method).

combined - includes elements of production of two other methods.

Innovative technologies in the production of trademarks and labels

Holographic technologies have been introduced for a relatively long time in the field of protection and identification of documents, packaging and labels. They, in contrast to optically unchangeable and easily counterfeited security elements, provide the possibility of obtaining optically variable graphic elements refracted by light rays. These technologies are called OVID, which stands for “optically variable image devices.” The consumer is attracted by the high quality of the image, as well as the ability to prevent falsification of the protected products for a long time. For this purpose, he is offered a number of original solutions that not only provide a high degree of reliability, but also an attractive appearance of the product.

There are a number of options available for manufacturing DOVID products. The simplest of them is mechanical transfer of structures. For this purpose, unattractive geometric structures can be produced, often used in packaging production.

Dot matrix with image is based on diffractive, light-refracting image points introduced one after another into the photoresist by means of two laser beams overlapping at the focus. By computer synchronized exposure and simultaneous movement of the photoresist, it is possible to record an image on the surface of a photographic material, similar to recording on a dot matrix printer. Here we are not talking about holographic technology, but about the mutual superposition of laser beams. The resulting image is not three-dimensional and has a relatively low resolution, and therefore the method has limited application in protective technology.

Way masking interference holography also finds application in label protection technology. While in the previous method two laser beams form one small point, this method requires an area of ​​overlap of both laser beams, the extent of which exceeds the size of the future image. By applying the mask layer very closely to the photoresist, it is possible to create a clearly defined image area. By repeatedly exposing a sequence of precisely positioned photographic masks containing the corresponding image components while simultaneously changing the direction of the rays, a two-dimensional diffraction image is obtained. Here you can reproduce both color and moving scenes.

Way electron beam lithography includes the same technology as the dot matrix method. The significant difference is the use of an electron beam to expose the holographic plate. In this way, each strip is described individually, which provides greater technical flexibility and accuracy. But its implementation takes a lot of time.

Classic 3D holography is a technique of optical physics as part of wave optics. Unlike previous methods, it is possible to obtain a true three-dimensional image on a two-dimensional medium. Here you can get all the optical information about the object. In this technology, recording is done on a special holographic film, which makes it possible to record a three-dimensional image.

A hologram may contain more than one visual element. For example, a security hologram for a banknote area includes up to 50 image elements or color elements that are arranged in different layers. The combination of the bright iridescent DOVID images with the properties of the classic rainbow embossed hologram not only creates a very effective protection against counterfeiting, but also, thanks to its aesthetic appearance, attracts the attention of the consumer and ensures repeated recognition.

To increase protection against falsification, combinations of different holographic security methods are used. Most often, combinations of a matrix laser interference method with a classical hologram are used.

Used for mass production copying methods on photoresist . During production embossed holograms a rainbow copy is exposed on it. This high-resolution material produces a holographic interference structure with a surface relief, which is subsequently formed by galvanic means and transferred to a nickel matrix. These dies serve as embossing tools in machines where heat and pressure are used to create a relief of less than 0.0005 mm in depth on the film material. This material is then used to create a secure holographic image.

Holograms of various structures are already widely used today in the production of banknotes, credit cards, and protection of goods, as a guarantee of the authenticity of securities. Holography is also widely used to protect brands. Labels equipped with holograms are often used for identification and also as a sign of product authenticity. There is every reason to believe that holographic security methods will find increasing use in the production and use of labels.

In the field of introducing the latest technologies for the production and use of labels, such technologies as the use radio frequency (RF) ,electromagnetics (EM) And acoustomagnetics AM , which are being intensively developed and have a good chance of being used, in particular, in label production.

One of the new ways to identify products by labels is the international standardized 13.56 MHz RFID (Radio Frequency Identification) technology . Market research has shown good prospects for its implementation on the market. This technology is particularly suitable for special applications, such as in the areas of logistics and goods transport, as well as incoming inspection and identification. The technology of so-called smart labels with an integrated transponder (transceiver on integrated circuits) has good chances for implementation.

For mass application of technology, one is especially attracted by its reliability and affordability. The well-known manufacturer of paper processing machines and devices, Bielomatic, has already developed a completely new machine concept. Future intelligent electronic paper products such as tickets (Smart-Tickets), labels (SmartLabels), etc. can be produced in large quantities rationally and with the ability to control by integrating special equipment with them.

RFID technology is based on transmitting data via radio waves. The recorder/reader transmits energy to the antenna in an electromagnetic field with an integrated circuit (chip). The exchange of data and energy is carried out in their two-way interaction. This ensures fast and reliable data exchange. Currently, information exchange can be carried out over a distance of 1 meter. The antenna/chip combination could, for example, be built into a card or any shell.

Transponder technology Compared to other identification systems, such as bar codes, it has significant advantages. Thus, data can be read without visual contact, the data recorder can be reprogrammed, and thanks to anti-conflict mechanisms, several transponder cards can be read simultaneously. In the most common systems, each transponder has a 32-bit serial number and a 256-bit user storage. Modern transponders can be integrated into labels without any problems, and in addition they can be sealed. As for the field of logistics, with the help transponder labels Reading devices can quickly and reliably identify containers with goods, identify products or determine where they are stored in a warehouse. This completely eliminates errors from manual data entry or reading dirty bar codes.

For marking goods or any type of packaging are used self adhesive holographic labels or combined labels (printing + holographic element) . Any label can be made on a destructible base, i.e. be sealed, which guarantees protection against reuse or unauthorized opening. Holographic tape is supplied for shrink sleeves.

Self-adhesive holographic labels. If the production of products with holograms is one-time, and the circulation ranges from several tens to several thousand, then it is most expedient, simple and economical to stick holograms manually, not forgetting to plan additional time for this operation. One person, depending on the type, size, configuration of the hologram, positioning accuracy on the surface of the product and other parameters, can stick on average no more than 500 holograms per hour, i.e. during a working day - approximately 4 thousand.

In cases where the circulation of holograms is several thousand and holographic labels need to be glued to finished products, manual labor can also be used. In this case, the work of sticking holograms is performed not by one person, but by several. You can also use label guns if your product allows.

When holographic self-adhesive labels are used in large quantities and their circulation amounts to millions of pieces, many product manufacturers install labeling machines in the production line, which are widely represented by domestic and foreign models. When starting up this equipment, take into account the specifics of the surface on which the hologram will subsequently be applied, including its nature (flat or curved); It is often necessary to apply a hologram at a corner, i.e. bend it at a right angle.

The range of materials on which holograms are glued is very wide: paper, leather, wood, plastic, etc.

The throughput of labeling equipment is usually calculated based on product production volumes plus some reserve in case of increased sales volumes.

In the modern world, holograms are one of the most reliable ways to protect a product from counterfeiting. With the help of holograms, documents, banknotes, and bank securities are protected in all countries. Of course, there is no absolutely reliable lock - you can find a key for any one. However, making holograms is a fairly reliable method of protection, since its cost makes it economically impractical to counterfeit the product, not to mention the fact that it is illegal. Making a holographic trademark for a brand quickly pays off, like any investment in marketing promotion. In addition, goldmi.com.ua reminds brand owners that there are several ways to produce holograms with different levels of protection, production time and cost.

What are holograms?

Depending on the manufacturer's goals, he may use different types of holographic products. Self-adhesive holographic stickers are very effective in protecting against counterfeiting. Their base can be self-destructive, which completely eliminates the possibility of its transfer to another surface. Holographic packaging tapes, paper or cardboard have proven themselves to be excellent. One of the most common types of holographic stickers is a label produced by hot stamping foil - one or two colored foil with an image is pressed onto the finished holographic background. This may be a logo, trademark, or other personalized information. In some cases, manufacturers use heat-shrinkable caps or transparent films that contain holographic elements to great effect.

All of the above are holographic stickers. Their advantages: low cost, speed of production, possibility of personalization. Among the disadvantages, one can only name a weaker level of protection compared to full-fledged holograms, which are made on the basis of the original master matrix. However, the level of protection they provide is quite enough to protect a mass-produced product from counterfeiting.

Unique holograms require significantly higher production costs. The complex and lengthy creation process fully pays off when it comes to protecting an exclusive product from counterfeiting.
