The SD460 uses holographic security by applying a special *holographic overlay or laminate* with its built‐in laminator. The material comes in cartridges that you load into the printer, and it’s available in 0.6 mil thickness (e.g., DuraGard OptiGram “Geometric Curves” yielding ~350 cards) or 1.0 mil clear laminate for longer life (up to 300 cards) . These laminates embed holographic designs that make cards harder to counterfeit while adding durability.
