Both topcoat and patch overlays can be clear or can have a transparent
holographic image on them. The holographic materials are called holographic
topcoat or holographic patch and can be ordered with a custom image.
In addition, both holographic topcoat and holographic patch can be designed with
a registered image that is located in the same position on each card. Registered
holographic topcoat has a registration mark so that the image can be aligned with
the card. Refer to the printer's Installation and Administrator's Guide for
information on ordering overlay material.
Registered Holographic Patch
If you use a custom holographic overlay, make sure that you know the location
of important card features, such as photos and logos. Do not place holographic
images where they interfere with the appearance of photos or machine‐
readable features.
