In the production of holographic anti-counterfeiting products, the final optical effects depend not only on the design itself, but also on the subsequent mastering process.
Especially when we process micro-nano optical structures, tiny particles in the air and changes in temperature and humidity can both affect the quality of lithography and recombination. That is why a stable, clean environment and precision mastering equipment are the key basis for maintaining the precision of the hologram master.
As we moved to a new production site, and to further improve our micro-nano optical mastering capability, we upgraded the existing mastering environment and equipment and built a dedicated Class 10,000 cleanroom for the hologram mastering system.
Below, we will take you to have a look at our clean workshop’s environment, its core equipment, and the mastering needs it can support.
1. A Class 10,000 Cleanroom for Precision Master Origination
Our newly upgraded Class 10,000 clean mastering workshop was completed and put into use in May 2026. It covers about 350 m².
It uses a PR yellow-light process and a full positive-pressure clean design, and it is a high-standard clean production space built for holographic security mastering.
It gives us a stable and reliable clean environment for making masters and doing hologram mastering origination work for high-precision micro-nano optical textures, ID document security, and hologram labels.
Why does a mastering workshop need such a clean environment?
During lithography and recombination, dust and tiny particles in the air can land on the surface we are working on. This can cause pattern defects, broken lines, or distortion of the micro-nano texture.
For sub-micron and nano-scale micro-nano optical structures, even this small amount of contamination can affect the final result.
That is why the workshop is built to the Class 10,000 cleanroom standard and equipped with a positive-pressure control system. By keeping the air pressure inside higher than outside, clean air keeps flowing outward. This greatly reduces the chance of outside dust and particles getting into the clean area.
At the same time, we strictly control dust particles, temperature, and humidity in the workshop to meet the requirements of the PR yellow-light process.
This keeps the effect of the environment on lithography and recombination as small as possible and gives high-precision micro-nano optical processing a more stable environment.
2. Multiple lithography systems for different precision requirements
Besides the clean environment, the equipment and process used for master origination also determine what kinds of optical structures you can produce.
Our IMAGE TECH clean workshop has a complete set of hologram mastering equipment, which covers the main steps for making it. Including master origination systems, mechanical recombination and UV recombination machines.
For the core lithography equipment, our workshop has two sub-micron lithography machines and three nano-scale lithography machines, which enable us to achieve various security features and optical effects.
Whether it is a standard holographic texture or a custom optical design that needs finer structures and higher precision, we can match the right mastering process and machine to cater to your projects.
This also gives us more ways to develop and customize different holographic security products.
3. From Fine Anti-Counterfeiting Details to Large-Format Seamless Patterns
With a high-standard clean environment and complete equipment, our clean mastering workshop can handle many kinds of business applications.
According to the design and application requirements of different projects, the workshop can support:
- Small-format fine security graphics – suitable for labels with high requirements for pattern details and optical performance.
- Multi-layer composite holographic structures – Combining different optical structures into one integrated design, suitable for hologram ID cards.
- Large-format seamless texture masters – for large-area optical textures and continuous patterns. Suitable for packaging traceability and high-end security materials.
If your projects need special patterns, structures, or sizes, we can also match a suitable processing plan to the specific need.
4. Flexible production for both Initial R&D Projects and Batch Processing
Different projects have different requirements for the mastering process.
If your projects are still in initial R&D, you may need several rounds of adjustments to the optical patterns and micro-nano structures before finalizing the master.
Once a design is approved and moves into regular production, you may care more about consistency and on-time batch delivery.
To meet these different needs, our clean mastering workshop combines a mature PR yellow-light process, a mix of manual craftsmanship and automatic machines. So we can take on small-batch R&D and sampling, and also support standard batch holographic product delivery.
We hope a stable production environment and multiple lithography machines can give each project more flexible mastering support.
From fine optical patterns to complex micro-nano structures, from early R&D samples to batch mastering, every step has to balance processing precision, process stability, and actual application needs.
Bringing Optical Designs to Life Through Precision Master Origination
A well-designed optical effect is only the starting point. To reproduce it accurately in a finished holographic product, you also need a precise and reliable master origination process.
At IMAGE TECH, we continue to improve our micro-nano optical processing environment and equipment. Our Class 10,000 cleanroom provides controlled conditions for precision fabrication, while our different photolithography systems give us more flexibility in handling a range of optical designs.
Whether you are developing ID card security features, custom hologram stickers, or large-format optical textures, you are welcome to talk with us about a mastering plan that fits your project.
We will keep providing holographic mastering services with high resolution, high accuracy, and high stability to customers in the holographic security industry.
We help our customers build optical security products that are both easier to identify visually and harder to copy physically.
