First generation holograms were usually made with this
technique.
2D design has one layer hologram image on
surface which is made up of one layer two dimensional images.
The images are assigned different colors and position in one
layer. It just has only one layer, without visual hologram
depth as 2D/3D hologram. But 2D hologram text and image can be
very shining, colorful, especially small font text is very
clear on hologram image and text is on surface. Although a 2D
hologram has one level it still looks nice and colorful. Perhaps such
holograms are these days preferred more for promotional
applications. Such holograms may have a flip effect to enhance
the aesthetics.
Security ratings are generally considered low for this
technique
