Dafu Video- Workshop for German Optical PC production line
Holographic film is a very thin, flexible plastic film [Polyester (PET), Oriented Polypropylene (OPP) and Nylon (Bonyl)] which has been micro-embossed with patterns or even images. Patterns (such as checker plate or diamonds) or an image (such as a tiger) are created by way of an embossing process which can provide a remarkable 3-D effect and/or spectral (rainbow) coloring. The embossing process is akin to cutting tiny grooves into the films surface at various angles and in different shapes. These micro-embossed grooves cause the “diffraction” of normal white light into stunning spectral color. This phenomenon is not unlike the diffraction of white light into spectral colors through a crystal prism.
You will see different images and the colors depending upon the position and angle from which you are looking at the film. The image and spectral coloring will change as you view the grooves at different positions and from different angles. Many holographic films are metallized with Aluminum. Not only does this protect the embossed surface and reflect light through it, it also provides a more colorful, crisp and bright image.
