Brief of how to make Laser Hologram Decal.
Briefly discussed below is the process of making a typical two-layer " Embossing Reflection Laser Hologram ", by far the most common and cost-effective laser hologram , with two common sub-types, namely the two layer laser hologram (with a background image and a foreground image) and the three layer laser hologram (with a background image, a middle ground image and a foreground image). Our laser holograms are made on a large stable table with a laser, lenses, mirrors and other optics. The table is composed of a large mass resting on a vibration isolation system to dampen any movement. Since the laser hologram records light waves, movement as small as one-quarter of a wavelength of light will ruin the laser hologram.
To make a laser hologram, the laser beam is split into two beams. One part of the laser beam is directed by mirrors and spread by lenses to illuminate the object. The laser lights the object, then bounces off and hits the holographic film or plate positioned in front of the object. The other portion of the laser beam, called the reference beam, is directed by mirrors and lenses to evenly illuminate the film. Where the two portions of the laser beam meet at the film, they interfere constructively and record the laser hologram.
This "constructive interference" of laser light's waves is similar to the ocean's waves traveling onto the beach. When two waves meet just right, their collision enlarges or amplifies their size. In holography, this wave amplification exposes the holographic film.
After exposure, the holographic film is developed, similar to black and white photography. After processing and drying, the laser hologram is ready for viewing. This series of steps results in a laser-viewable "Master" laser hologram.
White-light viewable laser holograms are created in a two step process. First, the laser-viewable Master is holographed. Then, a second laser hologram is made from the projected pseudoscopic image of the Master. This laser hologram can be reconstructed - viewed - in white light. The section on "Lighting Instructions" explains viewing a white-light laser hologram.
Lighting Instructions
A light is needed to illuminate a laser hologram. A laser hologram is illuminated by shining the light at the center of the laser hologram. For ease of viewing, this angle is usually about 45 degrees from the center of the vertical laser hologram to the light source. This lamp should be at least four feet above the laser hologram for the best results.
For best clarity, there should be no other lights striking the surface of the laser hologram.The quality of the light source that illuminates your laser hologram is very important. The sharper the light source, the sharper the image in the laser hologram. We recommend a light that uses a 12 volt, 50-75 watt MR-16 quartz halogen bulb.
Another light which works well is the Phillips Master Line, 60 watt PAR-16, narrow spread. These lights can be purchased at most lighting stores. The light should be at least four feet away from the laser hologram; and shine on the laser hologram from above at an angle of approximately 45 degrees. Reflection laser holograms use front lighting. Transmission laser holograms are illuminated from behind.
Design / Artwork / Origination
Working with you, our graphic team is going to transform your ideas into laser hologram by developing them in a best way. Designing marvelous visual effects and multi dimensional graphics with color and action unity is possible by using advanced computer techniques.
Artwork file in Corel Draw or Illustrator format is best. Artwork in Corel Draw file can be used for Master Origination Mold(nickel mold) shooting directly. Please save file in Corel Draw version 8 file. The Corel Draw artwork file should be converted into curves. So we can open it. Adobe Photoshop file, JPG, GIF, is ok, but not the best solution.

Mastering
Prepared model work is sent to laser hologram laboratory. Our expert physics engineers in their fields create Master laser hologram on a special sensitive emulsion by combining necessary photographic and holographic elements. As it happens in all laser holograms, this multi dimensional image is recorded by using laser beams and sensitive optical techniques. Exposing "the positive" of each layer, one after the another, to laser light with the aid of specialized imaging devices such as specialized lenses and mirrors and recording the same on a surface of an ultra clean, photo sensitive and specialized glass plate, to originate "the Glass Master". At the end of this intricate and time-consuming process, the original two dimensional image of the artwork gets "transformed'" into a "three dimensional" impression on the surface of "the glass master", called the laser hologram. The laser hologram will diffract the seven colours of the spectrum (colours seen in a rainbow) and will produce "the depth effect" or the three dimensional (3D) effect, when it is viewed from different angles under any type of natural or artificial light, thereby giving it an extraordinary visual appeal. During holographic recording, secret information (e.g. code number) can be recorded and concealed in one of the layers of the laser hologram to make it machine readable only (that is, under special lighting conditions and with the aid of special viewing instruments) in order to impart the inimitable "optical security feature" to the laser hologram.
Electroforming
The laser beams that are loaded on master plates are transferred to the electroformed metal plates with the aid of chemicals.
Transferring the multi-coloured, three-dimensional impression of the laser hologram from the surface of the glass master to the surface of a nickel plate to create " the nickel master ". (After this, the glass master cannot be used any further and has to be discarded.). By the same process and from " the nickel master ", additional nickel plates, also called " shims " are prepared for ultimate use in the embossing machine for mass production.
Embossing
Stamper shims are mounted in embossing machines.
Transferring the multi-coloured, three-dimensional impression of the laser hologram from the surface of the shim to the surface of very thin, metallised polyester film roll, through optimal application of heat and pressure. A special chemical coating known as "Tamper Evident Coating'" on the base of the polyester film imparts an important additional security feature to the laser hologram, to detect any attempt at its unauthorized removal from the surface of a product or of its packaging or of a document.
Adhesive-coating and lamination: ( only for pressure sensitive label only )
The " embossed " roll is continuously coated on its reverse with a water-based / solvent-based pressure sensitive adhesive and dried and is thereafter continuously laminated with the silicon-coated surface of the release paper to make a laminated roll.
Die-Cutting
After lamination, the laminated roll is then duly in the size and the shape required by the customer by a very specialized automatic die-cutting machine. For jobs required in Spool Form the laminated rolls are slitted as per size. Laser Holograms in Sheet Form are best suitable for manual affixations while Spool Form for automatic affixations.
Removal of the un-embossed portions of the metallised polyester film from and side-trimming of each sheet bearing several pieces of the laser hologram to make the sheet uniform in size and facilitate removal of laser holograms, one by one from the surface of the sheet.
Slitting(ifin roll) and packaging
Slitting sticker in roll format or cutting into panels. The sticker sheet will be packed 200 sheets one bag.
The laser holograms are then finally passed through the quality control department, where each and every property of the laser hologram is thoroughly checked and finally these laser holograms are counted, packaged and shipped
