Technology

The materials and the machines behind the film

This is the detail underneath the three steps — refractive index chemistry, origination and tooling, the casting line and the conversion equipment. For the shorter version, see how we make it.

Our world class infrastructure & technologies

Our team has unparalleled expertise in custom high-performance UV materials, coatings and process chemistry. Our solutions are built on precision micro-structures tailored by high-throughput web-to-web UV replication.

Design, origination & tooling

Producing precision micro-optic films requires the creation and optimisation of designs. Our team converts those designs into a diverse set of complex tooling for all types of application.

Advanced UV materials

UV materials with extreme properties — ultra-high and ultra-low refractive index — are the basis of our work. The higher the refractive index, the higher the efficiency of our lenses and optical features. The secret is the right chemistry.

R2R precision casting

A tailored, high-throughput UV coating and casting technology for replicating precision surface topography, followed by registered micro-printing, at the highest aspect ratios onto film surfaces up to 1.1 metres wide. Our formula for cost-effective precision.

Conversion

We also convert films into finished products: anti-counterfeiting labels, tags and tapes for your packaging, and ultra-fine security threads that can be woven into textile and brand labels or used for stitching.
