Watermark

Watermarks and holograms are near-translucent graphics printed over cards to increase visual authenticity. Watermarks are often holographic, meaning they appear to change based on the light and angle at which they are viewed. This effect can be achieved during the printing process or by applying hologram stickers by hand. Watermark-capable ID printers use an overlay ribbon or the “O” portion of a combined ribbon to produce the effect. Holographic overlays protect cards from wear and tear and making tampering and counterfeiting more difficult.
