Anti-counterfeiting technology is evolving from a 'single barrier' to a 'triple barrier' — the barrier of materials chemistry, the barrier of optical physics, and the barrier of digital encryption.Optimistically estimated to enter the commercialization phase between 2028 and 2030, with initial applications targeting anti-counterfeiting for high-end luxury goods and critical documents/certificates.The technology iteration in the anti-counterfeit printing industry entered a stage in 2025–2026 where “physical limits are being approached, digital trust is sinking to the item level, and cross-domain convergence is accelerating.” According to the China Anti-Counterfeiting Association’s 2026 Annual Excellence Cases, mass-production solutions from several leading enterprises, and public disclosures of multiple invention patents, the six technologies below have moved past the laboratory phase and completed commercial validation in sectors such as alcoholic beverages, daily chemicals, pharmaceuticals, precious metals, and publishing.

One、Micro/Nano Lithography: From “Hologram Stickers” to “Naked-Eye 3D Structural Color”

The biggest Achilles' heel of traditional holographic laser paper is that it can be reproduced through scanning and re-photographing, and transferred via chemical peeling. In 2025–2026, micro/nano lithography underwent a generational leap.

Technical Principle：Using electron-beam or laser direct-writing equipment, sub-micron periodic structure arrays (200–800 nm) are engraved into a photosensitive resist layer. By tuning the grating period, orientation, and depth, visible light undergoes interference at specific angles, producing color shifts and stereoscopic images visible to the naked eye. Unlike conventional holograms, the color of micro/nano structural color arises from physical structures rather than dyes — making it impossible to reproduce via color copying or scan-and-rephotograph methods.

Mass-Production Cases：In Fenjiu’s “Three-Defense-One-Traceability” (anti-forgery, anti-theft, anti-recycling, full-chain traceability) solution, the 3D cloud-film element shifts its image layers at a 30° tilt — consumers can verify authenticity with the naked eye and no auxiliary device. Jiannanchun adopts ring-shaped multi-color optically variable technology: annular fluorescent fibers are randomly scattered across the substrate, changing color as the label is rotated under UV light, and a counterfeiter cannot reconstruct the random fiber distribution. Shandong Taibao’s scheme for Jiannanchun goes further — stacking 3D color-shift varnish (optically variable magnetic 3D) with the ring-shaped multi-color optically variable layer to produce a dynamic anti-counterfeit effect of “one item, one variation; one turn, one color.”

Industry Significance：Micro/nano lithography elevates anti-counterfeiting from pattern recognition to physical-structure recognition. To replicate it, a counterfeiter would need lithographic equipment of equivalent precision — raising the investment cost from a few thousand yuan for a scanner to millions for an electron-beam lithography system. The economic barrier has risen dramatically.

Two、Anti-Replication Film-Forming Coating: Sealing the “Old Bottle, New Liquor” Recycling-and-Refurbishment Loophole

High-end baijiu and cosmetic packaging have long been a major hotspot for counterfeiting through recycling and refurbishment. In 2025, anti-replication film-forming coatings entered commercial large-scale supply.

Technical Principle：A functional coating with mismatched polarity is inserted between the aluminum-plated layer and the printed layer. Under normal conditions, the coating bonds firmly to both adjacent layers. However, when a counterfeiter immerses the old package in organic solvents such as acetone or toluene to strip it, the functional coating develops stress cracks or interlayer delamination due to the polarity mismatch — causing the information layers (trademark, batch number, anti-counterfeit pattern) to be destroyed simultaneously, rendering them impossible to transfer intact onto a new package.

Mass-Production Cases：The anti-replication film-forming coating supplied by Pulasi Packaging for Wuliangye has passed three phases of mass-production validation and now fully covers both the liquor bottle caps and body packaging. The technology has spilled over from baijiu into high-end cosmetic bottles — and the Asia-Pacific packaging lines of brands such as Estée Lauder and Lancôme are currently running onboarding tests.

Technical Specifications：The coating withstands temperatures ranging from –20°C to 120°C, endures more than 50 alcohol-wipe cycles, and achieves an information-layer destruction rate of ≥95% after attempted stripping.

Three、Invisible Dot Matrix + Visible Code, Dual-Layer Code System: The Mainstream Solution for Daily-Chemical Anti-Counterfeiting

In 2026, the anti-counterfeiting technical standard for daily-chemical lines was upgraded from “a single QR code” to “a dual-layer code system.

Technical Principle：The top layer is a publicly scannable, color-variable QR code carrying product information, batch numbers, and marketing entry points. The bottom layer is an invisible laser dot matrix readable only by the brand owner’s dedicated reader — formed by ablating micron-scale pit arrays on the substrate surface using a specific-wavelength laser, with pit diameters of 10–50 μm and depths of 5–20 μm. Ordinary photocopying or photo re-imaging can only replicate the top-layer code; the covert coordinates remain inaccessible, drastically reducing the success rate of batch counterfeiting.

Mass-Production Cases：The Baomu Huatian (Half-Mu Flower Field) personal-care line was built on the Oracle Super Code platform, with voice point-reading and anti-lift structures added on top. Industry field-test data shows: even when the invisible dot matrix suffers damage exceeding 10% of its area, it remains decodable, with a successful read rate of 99.3%; and once the surface code is copied, the backend can compare the covert coordinates to instantly flag it as counterfeit.

Extended Applications：COFCO Fine Wine’s (Zhongliang Mingzhuanghui) wine traceability solution has been further upgraded to a triple-factor verification of “color-variable code + bottle-body optically variable ink + backend import customs declaration data”: when consumers scan the code, they see not only the product information but also the full-chain clearance data of that specific bottle — from the overseas château to the domestic warehouse.

Four、Nanophysical Marker: How Precious-Metal “Digital Passports” Break the Evidence–Object Split

The precious metals and jewelry industry has long faced a structural problem: the certificate is one thing, the object is another, and the two can be circulated separately. In 2026, nanophysical marker technology provided the answer.

Technical Principle：Data is encoded into nanocrystalline materials (particle size 50–200 nm) and then permanently marked onto the metal surface as an invisible identifier via ion implantation or laser cladding. The mark introduces no impurities, does not affect the metal’s purity or weight, and withstands high temperatures (800°C), abrasion, and acid/alkali exposure. Specialized reading devices decode the information by exciting the nanocrystals’ fluorescence or Raman signals.

Mass-Production Cases：The “Baoyuan Code” (Treasure-Source Code) solution jointly launched by Gaoming Kewei and the National Gemstone Testing Center (NGTC) has been deployed at scale in the gold buyback loop. Every gold bar and every coin has its nanophysical marker embedded at the casting stage, bound on-chain to the NGTC certificate data. At repurchase, the recycler holds a reader and completes the “object-evidence unification” check in one second — permanently closing the industry’s chronic loophole of “genuine certificate matched to fake gold

Technology Expansion：The technology is now extending into high-value items such as diamonds, jadeite, and luxury watches, and is expected to cover major domestic jewelry testing institutions by 2027.

Five、Blockchain + AI Vision: From “Post-Facto Authentication” to “Pre-Event Alerting”

Between 2025 and 2026, the role of blockchain and AI vision in anti-counterfeiting shifted from a “nice-to-have” to a “core component.”

Technical Principle：Blockchain solves the trust-anchoring problem of “the code can be copied, but the backend data cannot” — every code’s generation, activation, scan, and circulation record is written on-chain, immutable and traceable. AI vision, on the other hand, handles proactive anomaly detection — by analyzing massive scan-data features such as time, location, frequency, and device fingerprint, it builds a model of normal circulation flow. Once abnormal patterns emerge — such as the same code being scanned 100 times in one hour, or the same IP address continuously scanning different products — the system automatically triggers an alert.

Mass-Production Cases：The AI vision anti-counterfeiting system built by Panpass for COFCO Fine Wine raised the counterfeit interception rate to 90% after going live in 2025, and predictive anti-counterfeiting shortened law-enforcement response time to the 6-hour level. The system has processed over 200 million scan events cumulatively and built more than 300 abnormal-behavior feature models.

Industry Impact：AI vision anti-counterfeiting is shifting from passive verification to active defense — enabling brand owners to locate counterfeit operations before fake goods ever reach the market.

Six、Quantum-Dot Tagging: Front-End Exploration Toward the Ultimate Next-Generation Anti-Counterfeit

Although not yet in large-scale commercial use, quantum-dot tagging has entered the pilot-scale validation phase and is regarded as the “ultimate next-generation solution” for anti-counterfeit printing.

Technical Principle：Quantum dots are semiconductor nanocrystals measuring 2–10 nm in size, exhibiting a unique quantum confinement effect — quantum dots of different sizes emit different colors of fluorescence when excited at a specific wavelength. Dispersed in inks or coatings, they form a “spectral fingerprint.” The quantum-dot formulation for each product batch — including size distribution, doping concentration, and host matrix — can be made unique and reverse-engineering-proof.

Current Progress：A quantum-dot anti-counterfeit ink project jointly run by a leading domestic anti-counterfeit company and an institute of the Chinese Academy of Sciences has completed both lab-scale trials and pilot-scale validation, and is now undergoing a 100,000-unit-level mass-production verification on liquor packaging. The technical bottlenecks lie in the long-term stability of quantum dots (light exposure, temperature-humidity aging) and batch-to-batch consistency at full-scale production.

Expected Timeline：Optimistically estimated to enter the commercialization phase between 2028 and 2030, with initial applications targeting anti-counterfeiting for high-end luxury goods and critical documents/certificates.

The underlying logic of technological iteration：Threefold Barriers

Looking back at these six technological breakthroughs from 2025–2026, a clear logic can be distilled：Anti-counterfeiting technology is evolving from a 'single barrier' to a 'triple barrier' — the barrier of materials chemistry, the barrier of optical physics, and the barrier of digital encryption.
