90° Switch Effect
90° switch eﬀect text and imagery is invisible when viewed at a normal position and clearly visible when viewed at a 90° angle.
90° Viewable Element
This text and/or imagery is faintly viewable at a normal position and clearly visible when viewed at a 90° angle.
Achrograms are colorless images with positive and negative components that swap when viewed at a 90o angle. Colorless images are not easy to replicate or simulate on standard commercially available origination equipment.
Composed of neutral grays, white, or black, achromatic images, lines, and text have no color refraction. When placed within a highly diﬀractive image, this non-diﬀractive element is easily located and veriﬁed by the trained eye. Very few originators are capable of creating achromatic elements, making them extremely diﬃcult to counterfeit.
Letter Lens Effect
Created to resemble characters viewed under a magnifying lens, these letters appear and move when viewed under a point light source.
An excellent contrast to the surrounding, colorful holography, the semi-opaque, non-diﬀractive matte ﬁnish is easy to identify and authenticate. Its appearance remains unchanged, regardless of the viewing angle.
Images refract their true colors only when viewed at a very speciﬁc angle. Holograms, which refract the seven colors of the spectrum (red, orange, yellow, green, blue, indigo, and violet), can be used to display the true colors of an image, such as a national ﬂag (it is not possible to specify Pantone colors). As the viewing angle is tilted, the colors sequence through the color spectrum, making this an easily authenticated device.
Created with highly complex security print software, wireframed (outlined) words and objects can be combined with other eﬀects to create more complex images.
