Encryption, Hidden Text/Image Hologram

Covert Laser Readable (CLR) Hidden Text/Image Samples Page 1 2 3 & Moire Hidden Text Samples Page 1 2

There're two kinds of hidden text or images available for holographic stickers. These two kinds of hidden features improve the hologram stickers security feature very much agaist counterfeit. One called covert laser readable(CLR) hidden text which hidden text of image just can be seen with help of laser pointer (laser reader). The laser readable hidden text can be simple logo, word or other imaged. Another type hidden text is morse hidden text, also is called morie hidden text, which uses decode film to see the hidden text in hologram. When decode film cover the hidden text area, you'll see hidden image/text. We also successfully developed very high security amination laser hidden text too. For example, you can see a flying bird or many flips of word or images in kinematic movement hidden text. It's the best security hidden text. Covert image/covert text in hologram will help original holograms tofight against counterfeit very much.

Moire Hidden text/image or Raster effect, is a hidden effect which also called moire Effect or Decode film hidden text in hologram.

This dot-matrix holographic sticker has two kind of hidden text recombine together.

Hidden text(covert image) or image feature hologram is invisible to naked eyes in sunshine or normal lighting conditions.Hidden text(covert image) or image just can be seen with sepecial laser pointer. Hidden text(covert image) or image feature hologram is invisible to naked eyes in sunshine or normal lighting conditions.Hidden text(covert image) or image just can be seen with sepecial laser pointer (or called laser reader).

Moire patterns are often an undesired artifact of images produced by various digital imaging and computer graphics techniques, for example when scanning a halftone picture or ray tracing a checkered plane (the latter being a special case of aliasing, due to undersampling a fine regular pattern). This can be overcome in texture mapping through the use of mipmapping and anisotropic filtering. The drawing on the upper right shows a moire pattern. The lines could represent fibers in moiré silk, or lines drawn on paper or on a computer screen. The nonlinear interaction of the optical patterns of lines creates a real and visible pattern of roughly parallel dark and light bands, the moiré pattern, superimposed on the lines.
