Retransfer Film – Transfer Security Overlay for Cards & Booklets

What Is Retransfer Security Film for Cards?

Our retransfer security film, also known as transfer security overlay, is a hot-transfer film designed to protect printed information on both card-type identity documents and booklet-style passports.

The security feature coatings are thermally transferred to the surface of the card or booklet substrate, offering excellent protection against daily wear and tear.

How Does Our Retransfer Film Work?

During the retransfer process, our security film is hot-transferred directly onto identity documents containing individual personal information.

The security coatings permanently bond to the substrate surface, creating a durable, tamper-evident protective layer that withstands abrasion, bending, and chemical exposure.

What Security Features Are in the Retransfer Film?

Each retransfer film incorporates a DOVID (Diffractive Optically Variable Image Device) — a diffraction-based security feature suitable for plastic substrates used in government-issued ID cards and driver’s licenses.

What Security Levels Can We Provide?

Our retransfer films meet all three security tiers:

• Level 1 (Overt) – Visible holographic and color-shifting effects
• Level 2 (Covert) – Hidden authentication features
• Level 3 (Forensic) – Advanced laboratory verification

Why Choose Our Retransfer Security Film?

We are specialists in optical security solutions. With innovative design and high-performance materials, we help you reduce risks of tampering, alteration, and forgery.

Every design can be customized to reflect your country or city’s cultural symbols, emblems, or language. Our manufacturing complies with ICAO and international security standards.

What DOVID Effects Does Your Retransfer Film Support?

Our DOVID technology enables:

• Dynamic chromatic and holographic effects
• 2D/3D image depth
• Kinematic motion effects, moving images when tilted
• Color-changing diffraction gratings
• Micro- and nano-structures for copy resistance

These eye-verifiable features are extremely difficult to counterfeit, ensuring long-term protection for identity documents.
