01. History of Hologram ?

The behavior of light has fascinated few greatest minds from Galileo to Einstein. In similar pursuit, in the year 1947 a Hungarian born English Scientist named Dr Dennis Gabor invented Hologram and earned Nobel Prize in 1971.

All conventional imagery shows only two Dimensions that is Length and breadth, but his invention showed the hitherto unknown third dimension viz Depth, thus he coined an apt term Holo-Gram which in Greek means Whole - Detail.

02. How a Hologram is produced?

A Laser, selected optics, a Photosensitive Plate and either an artwork or an object are mounted on a vibration-free table installed in a completely dark and dead room. The exposure must be made in an environment void of any movement or vibration. Even movement to the degree of half a wavelength of light will prevent the recording of the image on the film.

A beam of laser light is optically separated into two beams. One, the reference beam, is directed toward a Photosensitive Plate. The second is called object beam is directed at the subject to illuminate it fully.

When the object beam reflects off the subject, it carries with it information about the location, size, shape and texture of the subject. Some of this reflected object beam then meets the reference beam at the Photosensitive Plate, producing an interference pattern, which is systematically recorded on the photosensitive plate.

After the film is developed, the hologram is illuminated at the same angle as the "reference" beam during the original exposure to reveal the 3-D image. Thereafter a series of further processes are carried out under rigid parameters to finish Holographic Products based on individual customer’s need.

03. How do Holograms work ?

When a Beam of Light strikes a Hologram at the proper angle, a Multi-dimensional Image will appear - Direct Sunlight or a Single Overhead Spotlight is the best way to illuminate Holograms with deep Imagery. Embossed Holograms, with their Shallower Imagery, can be viewed when lighting is less than ideal - under Fluorescent light etc.

04. What is an Embossed Hologram ?

For a large amount of Holograms to be produced in a Cost Effective manner, a method was developed to Emboss very complex microscopic patterns onto rolls of very thin Plastic or Foil Materials. Light Diffracts through these patterns to Create the Holographic Image. Embossed Holograms cannot Copied using Normal Printing and Copying Technologies.

05. What are the different types of Embossed Holograms are available?

3 D - These Holograms display a Three Dimensional Image which looks identical to a Real Object. The viewer can literally "Look Around" the "Top" and "Sides" of the Object just as if the actual object was there. A 3D Hologram is a "Spectacular" thing to watch and people are fascinated.

2D/3D - These Holograms display a unique Multi-level, Multi-Colour effect. These Images have One or Two levels of Flat Graphics, Floating Above or at the Surface of the Hologram. Background Artwork seems to be 2D or 3D Holograms. They are extremely eye-catching and enjoyed by Children and Adults alike.

Stereogram - This type of Hologram originate with Cinematic Footage that is Processed Holographically to create and Multi-dimensional Effect. Special Effects, Computer Graphics, Animated Subjects and even Outdoor Scenes can all be utilized as Elements of Stereograms, which are also known as Multiplexes.

06. What is a holographic stereogram?

A series of pictures created by recording multiple two-dimensional images captured from different angles using a video camera moved past the front of the target or an image set synthesized via computer graphics is combined into a single hologram.

Lippmann holographic stereograms can be produced by two methods. One is a one-step technique in which the image synthesized from the original picture is recorded directly as lines or dots at a scale of a few hundreds of microns; the other is a two-step technique in which the original pictures are first recorded onto a hologram master to create an intermediate master.

07. What is Multi-channel Hologram?

They show a few different images, usually changing from side to side. Most commonly 2 or 3 channels are used. It is like making a few "shots" on the same piece of film from different angles. Stereograms are the ones that show a smooth movement. They are a bunch of few hundred frames - a little bit like a cartoon movie animation.

They can be computer generated, made from digital video or movie tape - showing a short sequence of some action.

08. What is Holographic Portraiture?

The hologram forms the real volumetric image, unlike a photo and even such imitations of volumetric images, as stereograms. The reality is that the hologram can be observed from different points, observing parts of object or scene, which were hidden from other point of view. In this sense, the holographic image behaves completely life-like. The dynamic range of brightness on the hologram is much higher, than on a photo. On the paper, image's brightness is formed by subtraction of the maximal brightness, but on the hologram - redirection of light from dark sites to bright. Just it explains a surprising reality of images of transparent subjects, such as glass, water drops, that is those objects, which actually have very large dynamic range of brightness.

Nevertheless, unlike photos and pictures, it needs a focused light sourceto observe the holograms, in other case the image is slightly blurred.

09. Can you create a Hologram from a photograph?

Yes, and no. It is possible to make a hologram of photograph, but photograph itself contains flat, 2-D image information. Therefore, on the hologram it will also look flat. It would look just like a flat photograph floating in the space on front, or behind the frame. The third, missing dimension of a photograph cannot be reconstructed by holographic process.

10. What is the best way to display hologram?

Transmission hologram need light behind them, therefore home displaying is rather tricky with transmission hologram. Reflection holograms require single light source from front-above, more-less 45 degrees. These are much easier to display, and are suitable as home decor. Usually light creating strong shadow contrast is the best, and soft or multi-source light will blur the image. Most convenient is to display holograms at eye level, so they can be visible from a distance without a problem.

Most of today's holograms are white light holograms. You would need just a regular source of light, like a track light, halogen spot or clear light bulb shining directly on the picture.

11. Can the image be enlarged or reduced?

It is possible, but very complex and expensive. For this reason the natural choice is to create holograms in 1:1 size.

12. Will a hologram last long?

Holograms are very durable, and with proper care will outlive any regular photographs or prints.

13. What are the most popularly used Holographic Mastering Technologies?

2D/3D:

2D/3D is a traditional three-dimensional hologram the impressive looks of which is based on several graphical layers. This kind of a hologram is produced on breakable adhesive material, or it is foiled directly onto the printed matter. The visual looks of a 2D/3D hologram is implemented in accordance with the customer's wishes and graphical guidelines

3D:

In addition to color shift, the most unique characteristic of a hologram is the 3D effect. We can make true 3D hologram image by recording a 3D model. Holograms made with this techniques are difficult to duplicate.

Dot Matrix:

In this technology, the 2D pattern is created using microscopic pixels. The end result is a hologram, which functions well also in dimly lit conditions. Hidden information can be included in this security hologram type as well. The visual look of the hologram is designed in accordance with the customer's wishes and graphical guidelines.

Multi-channel:

Employing light guide theory, we are able to make one image visible in a defined area at an angle. We manipulate the technique to encode multiple images in a small area, and that makes our hologram harder to duplicate.

E-beam:

This technology uses electron beam to etch the pattern of the holographic fringe directly on a photo-resistant plate. This technology features high resolution and high precision. Therefore, we can engrave fine images with rich colors using this technology. This is also called as Electron Beam Lithography.

14. To commence the job what are details I need to provide?

The process starts with one of our security consultants talking with you to make sure we fully understand your needs. We would then ask you to send us some simple artwork showing basic elements of the hologram you want to create. If you do not have any artwork then our art division can create a unique one based on your guidance.

15. Is it possible to finalize the exact details to be used for making Hologram?

Yes, after you have sent us a basic brief, we would make a counter artwork that would cover all the relevant details of the proposed Hologram. During such exchange of details between us, you are free make whatever changes or additions you like. Once you return the approved artwork to us we would then produce the holographic image matching it.

16. Can I make corrections once the Hologram is originated?

The Holographic Master Development is an irreversible process under rigid parameters. So , once a design is mastered based on an Approved Artwork absolutely no modification is possible, however minor it may be. Thus, prior to handing over the approved artwork, potential customers must discuss all the matters related to the Job exhaustively. Otherwise, a fresh Mastering has to be developed at an additional cost.

17. Will the Hologram be the exact replication of approved artwork?

Owing to intricate designing process and owing to certain intrinsic phenomena, Holographically developed Image is likely to look a bit different in comparison to the conventional Artwork, which is inevitable.

18. What is the Budget?

If you are a bargain hunter or your budget is extremely challenging, please call us to inquire about unpublished special pricing.

19. Is it costly?

Whether you compare the price to the amount your company can save from reducing counterfeiting or compare the price to competing technologies, then the answer has to be no. Hologram is the most cost-effective authenticating technology available. If you have a particular project in mind then please feel free to consult with us.

20. What is the lead time?

From receipt of your instructions it will take about 3 to 5 working days to send you the preview artwork. From the receipt your approval at our end, it will take, depending on its complexity, another 10 to 15 working days to send you a viewing plate of the actual hologram. From the date of receipt of your final approval, it takes between 15 - 20 working days to dispatch the first production material. These timings are guidelines and we at G Force Innoventions are keen to be as flexible as possible to fit into your time-frame.
