Overt Security Features

Overt features can be seen by the naked eye, and provide quick visual authentication of your product and/or brand. Visual overt features in a hologram can include:

Rainbow Coloring – Images, lines or characters that refract light utilizing the full rainbow color spectrum. The color changes as the viewing angle changes.

Gray Scale Coloring – Images, lines or characters that have no color refraction, but are composed of black, white or neutral variations of gray.

Wireframe Text – Outline of words and objects that can be combined with other effects to make a more complex image.

Multiple Channel (Switch) Effect – Two or more distinct images that occupy the same area of the hologram. These images shift from one to the other when viewed from different angles.

2D3D or Multiple Plane Effect – Images, lines, or characters that are composed of elements on the surface plane, above the surface plane or in the background. Elements above the surface plane or in the background exhibit a sense of depth and parallax.

Stereograph or Stereogram – An optical illusion of depth and movement created from one or more flat, two-dimensional images.

Guilloche Patterns - A series of high resolution lines, curves and rosettes or any combination of these elements. These designs are generated by using very sophisticated software. Each element can be assigned a predetermined color shift to create an illusion of synchronized animation.

True Coloring – Images that refract their true colors only when viewed at a very specific angle.

Embossed Effect – Optical illusion of relief created by a highly diffractive surface oriented grating that can be applied to images, text or lines in a hologram.

Animated Geometrical Shapes Morph – Geometric shapes that morph color as they are rotated.

Micro-Text - Is diffractive or non-diffractive text, whose size can be as small as 175 microns. And can be clearly viewed only with an eye loop or a magnifying glass.

Font Specific Text – Lines made from random fonts or words that look like ordinary lines until magnified to reveal the true object.

Latent Effect - Images, lines or characters that are designed to refract light at a very severe angle. The hologram has to be rotated ninety degrees in order to see the feature.

Holographic Watermark – A translucent relief of an image or text that causes some part of the image or test to appear convex.
