security holograms

Security holograms are the common type of holograms that are designed to help prove legitimacy of products in general against counterfeiting. This type of hologram not only enhances the visibility and security but also prevents unauthorized personnel from gaining access to sensitive materials. Mind you, adding a security hologram to your product does not mean that you are withstanding counterfeiting or copying but significantly it becomes a block for the counterfeiter.

The uniqueness of security holograms

Security holograms are incessantly becoming an essential method of protection against counterfeiting. The security a hologram provides depends to the extent tied to the extent tied to the complexity of image. What is so unique about these hologram is that they cannot be copied by standard printing techniques or fabricated by color copiers or any scanning equipment. That’s why it can be proclaimed loudly that security holograms virtually guarantees product authenticity and nothing else.

Purposes of security holograms

Security holograms which include stickers, labels, cards have different security levels. The significance of adding security hologram to a document or product depends upon the actual product value. This is because not all products deserve the similar protection and that is why different security holograms have varying security levels. Such holograms are used for various purposes.

Taking the help of tamper evident security holograms, you can protect your document from scanning and copying of your valued document or certificate. An added benefit to the hologram is the use of sequential numbers. .

In identity verification, security holograms play a pivotal role. They are applied on identification batches to enhance security and better visibility. It also prevents unauthorized person from gaining contact to sensitive materials.

In product authentication, the uses of such security holograms are indisputable. Now you can add to your product added security, visibility and the ability to distinguish goods from potential counterfeiters, using such holograms.

Some common applications

Security holograms are used in making apparel, Media software like DVD’S and CD’s, Banking documents, Transportation passes, Admission tickets, Consumer electronics, Gift certificates, Pharmaceuticals and many more.

Three-dimensional images, better known as 3d holograms are created by capturing a laser light interference pattern on film. Mainly, they are created by interweaving the coated graphics of one complete master image. The special 3d holography effects are created by printing graphics in register on back side of special lens material.

Materials for 3d holograms

The holographic 3d mostly comprises of two main material types. They are heavy gauge and fine gauge. The main distinction between the two is in the viewing distance. The thicker the lens the greater is the viewing distance.

Heavy gauge are used in those applications, which have superior viewing distances. Holographic 3d needs slower printing and finishing methods as the lens thickness restricts on the printing method. While the Fine gauge are used in those applications for closer viewing distances. They can be printed through printing press that allows good economy.

Characteristic Features of 3d holograms

A unique feature of the 3d hologram is the ‘parallax’. The unique term refers to the ability to view a scene and colors from many angles and depths. The colorful effect that comes from microstructures within the hologram often leads to the diffraction of the light striking them.

Another notable feature of 3d hologram is the complex optical patterns. The patterns contain information about the depth and photographic look of the image.

Various types of 3d holograms printing effects

3d hologram flips – This is regarded as the simplest of all animation effects. Here, an image changes or flips from one image to the next.

3d hologram zoom – This effect allows an image to move closer or farther away in the sequence of animated positions. The effect works best when the background is common through out for all the animated images.

3d hologram Morph – The Morph effects enables changes of one image to another image, using sophisticated image algorithms.

3d hologram Full Motion Video – This effect uses multiple frames of an action, which shows movement from the beginning till end. This effect is best obtained when the background remains constant throughout the sequence.
