Bring the Power of Microlens Film Production In-House.
The anti-counterfeiting market is growing rapidly, and microlens arrays are consistently ranked among the most secure optical technologies available. Their unique combination of overt and covert effects makes them incredibly difficult to replicate. Now, that formidable level of protection doesn't have to come from an outside supplier. The strategic advantage is unlocked by bringing microlens production in-house. This gives you ultimate control over your security, IP, supply c

Thermal vs UV Recombination: Choosing the right path for Optical films
In optical films and holography, “recombination” sounds esoteric, but it is simply the point where ideas in the design office become real square metres of structure. It is also where most projects quietly succeed or quietly die. Two families still dominate: thermal recombination and UV recombination. Both can produce good work. Both have long production histories. But they behave very differently once you start asking for tighter tolerances, higher brightness and more deman

UV Recombiner Upgrade: Higher Throughput and Improved Angular Control
We have now upgraded the platform with higher speed and improved angular control. In practical terms, this means tighter registration and more predictable results when scaling a master. The attached video provides a brief view of the upgraded system in operation. At XRD Nano, we take a long-term view. We keep proven machines current by integrating new technology where it adds measurable value, and we continue to add capability to new machines so customers can produce distinct

Farewell to Mercury Lamps: “Later” Has Arrived
In most security printing and hologram plants there is at least one machine that “only runs properly” on a mercury lamp. The lamp has more hours on it than some of your operators. No one is entirely sure where the RoHS file is. Purchasing has a quiet stash of spare lamps, bought “just in case”, and everyone pretends this is a plan. Regulators, sadly, do not share the joke. Across Europe and the UK, RoHS updates have already banned most general-lighting fluorescent lamps from

Holograms Still Win: The Cheapest Insurance Your Brand Can Buy
There comes a point in every successful brand’s life when somebody in senior management discovers counterfeiting. It is usually triggered by one of three events. First, the legal team forwards a link to an online marketplace where your product appears to be sold by “Premium Original Best UK Ltd”, based in a shed somewhere outside Shenzhen, at half your recommended retail price. Second, a major retailer hints that they are “seeing a few quality issues” and suggests, in that ch

The Silent Killer of Precision: Thermal Drift in UV Casting Machines
By nine the gauges insist everything is splendid. By half past two the machine has developed opinions. Thermal drift is not dramatic. It does not squeal or flash. It warms a little, expands a whisper, and moves your careful alignment from “microlens” to “soft suggestion.” Where the trouble begins LEDs that “run cool.” Charming phrase. They still warm the frame enough to nudge optics. Rollers with central heating. Temperature creeps, nip pressure wanders, contact lines rethink

The UV resin coating selector
A practical guide to calm beads, clean process windows and films that behave By Guri Dhillon, Founder, XRD Nano Ltd, United Kingdom Abstract Choosing a coating method for UV resins is a balance of viscosity, coat weight, web speed and cure strategy. This selector links viscosity at 25 °C to the methods that naturally work, the coat weights they tend to deliver, and the speeds they tolerate. It then offers simple rules for common nano imprint and micro optics tasks, with a few

In Praise of the Honest Data Sheet
There is a quiet document at the bottom of the website. It does not ask for attention. It simply tells the truth. It is the technical data sheet. Trade fairs love ambition. Banners promise revolutions by Tuesday. Videos glide in slow motion. A graph climbs like a ski jump while the axes hide. In the corner sits the data sheet. It clears its throat. It has numbers. It has test methods. It has footnotes. Truth is awkward because it insists on context. A modulus without temperat

UV Resin shrinkage and the science of curing wavelengths
A reflection on precision, chemistry and the quiet art of control in polymer replication By Guri Dhillon Founder, XRD Nano Ltd, United Kingdom Abstract Shrinkage is one of the oldest and most persistent challenges in UV curable resin technology. This article looks at why it happens, how curing wavelength influences dimensional stability, and what can be done in formulation and process control to achieve replication accuracy at the sub-micron level. Introduction The story of U

Why counterfeiting is the problem the Authentication Industry secretly needs
A reflection by Guri Dhillon, Founder, XRD Nano Ltd (UK) Most industries dream of solving their greatest problem. Ours quietly hopes it never does. Every year, billions are spent fighting fakes, yet the problem refuses to disappear. We design clever holograms, smarter inks, traceable codes, digital twins and new databases, while the counterfeiters continue to keep pace with astonishing agility. Perhaps this is not failure at all but balance, an unspoken understanding that kee
