What is Hologram Security Paper? Paper with Embedded Foil
Hologram security paper is a high‑security paper substrate that has a holographic foil strip, patch, or thread embedded into the paper itself during the papermaking process. Unlike a stick‑on hologram label (which is applied on top of the paper), a hologram embedded in security paper becomes an integral part of the sheet – it cannot be peeled off or removed without visibly destroying the paper. This makes it ideal for banknotes, passports, legal documents, certificates, cheques, and tamper‑evident labels. The holographic foil typically carries diffractive images (rainbow colours, 3D depth, kinetic effects) that are visible in both reflected and transmitted light. Because the hologram is physically fused with the paper fibres, it provides extremely high resistance to forgery and tampering. Hologram security paper can be produced with windowed threads (the hologram appears on the surface at regular intervals) or full‑width foil patches (larger holographic areas). It is often combined with watermarks, UV fibres, and security printing to create multi‑layer document security.

We work with specialised paper mills that embed custom holographic foils during paper production. We serve clients across India and worldwide, including Mumbai, Delhi, Bengaluru, Chennai, Hyderabad, Pune, Ahmedabad, Kolkata, Surat, Kochi, Jaipur, Lucknow, Nagpur, Indore, Vadodara, Ludhiana, Patna, Guwahati, Chandigarh, and many more.
🔍 How Hologram Security Paper Is Made
The production process integrates holographic foil directly into the paper pulp:
- Holographic foil preparation – A custom holographic stripe or patch is produced on a thin PET carrier (just like hot stamping foil). The hologram contains the desired security images (e.g., emblem, microtext, kinetic effects).
- Paper machine embedding – During the wet end of the papermaking process (when the pulp is still a slurry of fibres), the holographic foil is fed into the machine. The foil is positioned between two layers of wet paper fibres.
- Pressing and drying – The wet paper and foil pass through rollers that press the fibres around the foil, embedding it permanently. As the paper dries, the fibres contract and lock the foil in place.
- Optional windowed effect – For windowed threads, a special process exposes parts of the foil on the surface at regular intervals, while the rest remains inside the paper. This creates the classic “weaving” appearance seen on banknotes.
- Calendering and finishing – The finished security paper roll is calendered (smoothed) and then sheeted or wound. It is now ready for security printing (intaglio, offset, or letterpress).
🛡️ Types of Hologram Security Paper
- Windowed security thread paper – A narrow (1–4 mm wide) holographic strip that appears on the paper surface at regular intervals (windows). Widely used in banknotes (e.g., Euro, Indian rupee, US dollar).
- Full‑width holographic patch paper – A larger rectangular holographic area (e.g., 20×30 mm) embedded into the paper. Used for passport data pages, visa stickers, and high‑value certificates.
- Multi‑lane holographic thread paper – Two or three parallel diffractive strips embedded side by side. Increases security complexity.
- Custom‑shaped hologram paper – Holograms in the shape of a logo or emblem, embedded into the paper during production. Very difficult to counterfeit.
- Two‑sided hologram paper – The holographic foil is visible from both sides of the paper (either by using a transparent foil or by embedding it so thinly).
🔐 Security Advantages of Embedded Hologram Paper
- Peel‑proof – The hologram cannot be peeled off because it is fused inside the paper, not stuck on top. Attempting to remove it tears the paper.
- No adhesive degradation – Since no adhesive is used, there is no risk of adhesive drying out or losing tack over time.
- Copy resistant – The diffractive effect cannot be reproduced by scanners or printers. The embedded nature also prevents lifting and transferring.
- Transmitted light verification – Many embedded holograms are visible when held up to light (e.g., windowed threads show a continuous or broken line). This adds a second verification method.
- Compatible with security printing – Hologram security paper can be printed with intaglio, offset, or digital processes without damaging the hologram.
📦 Common Applications of Hologram Security Paper
- Banknotes (currency) – Windowed security threads with colour‑shift or kinetic effects. Used on almost all modern banknotes.
- Passports (data page) – Some passport data pages are made of security paper with embedded holographic patches (or laminated with holographic film).
- Certificates (birth, degree, marriage) – Embedded hologram strips prevent forgery of official documents.
- Cheques and bearer bonds – High‑value financial instruments often use hologram security paper to deter counterfeiting.
- Tax stamps and excise labels – Some tax stamps are printed on security paper with an embedded holographic thread.
- Legal documents (title deeds, court orders) – Prevents substitution of pages or tampering.
🌍 Holoseal’s Hologram Security Paper Supply Capabilities
We do not manufacture paper ourselves but work with specialised security paper mills that embed holographic foils. Our service includes:
- Designing custom holographic thread or patch designs – For banknotes, passports, or certificates.
- Coordinating the embedding process – We liaise between the hologram manufacturer and the paper mill to ensure precise registration and quality.
- Supplying finished security paper in sheets or rolls – Ready for your security printing press.
- Compliance with national standards – We ensure that the paper meets RBI, SPMCIL, or other government specifications.
With 15+ years of experience, we help government printers, central banks, and secure document issuers select the optimal hologram security paper for their needs – whether it’s a simple windowed thread or a complex DOVID patch.
❓ Frequently Asked Questions About Hologram Security Paper
Is hologram security paper more expensive than ordinary paper?
Yes – the embedding process adds cost. A standard sheet of hologram security paper may be 20–50% more expensive than plain security paper. For banknotes, this is justified by the high level of counterfeit protection.
Can I print on hologram security paper using a laser printer?
Not recommended. Laser printers use high heat, which may damage the holographic foil. For security documents, use offset or intaglio printing. For small runs, some inkjet printers work, but always test first.
What is the difference between a windowed thread and a full patch?
A windowed thread is a narrow strip (1–4 mm) that appears at intervals on the paper surface, giving a “woven” appearance. A full patch is a larger rectangular hologram that lies flat on the paper surface (but still embedded). Full patches are used for passport data pages and certificates.
Can hologram security paper be recycled?
Recycling security paper is difficult because the holographic foil (thin plastic + metal) does not break down in standard paper recycling. Most security documents are destroyed securely (shredded or incinerated).
How do I verify an embedded hologram?
Tilt the document under light – the hologram should show colour shifts, 3D depth, or kinetic motion. For windowed threads, hold the document up to light – the thread should appear as a continuous or dashed line.
How to order hologram security paper from Holoseal?
If you are a security printer or government agency, contact us with your required paper weight (gsm), size (sheet or roll), hologram design, and quantity. We will coordinate with our partner mills and deliver the finished security paper. NDAs and end‑use certification may be required.
