Our R2R metallisation enables the highly accurate and defined deposition of films like metals and oxides or combinations of both. Uniformity is ensured on a nm scale.
Metallised microscale structures are patterned using an R2R process. We partially de-metallise these structures with either a lift-off or an etching process – crucial for repeatable and efficient SmartMesh® production.
We have state-of-the-art clean rooms and experts for the development and production of nanoscale structures. Our equipment includes an optical direct-write lithography system for larger structures, as well as an electron beam gun for submicron features. We offer greyscale lithography that’s well suited for the production of complex surface geometries, such as inclined planes and lenses.
We develop and make our own embossing tools for R2R manufacturing, especially nanoimprint lithography (NIL). For large-scale foil patterning, we offer multiple UV embossing machines that have a higher web width than industry standards and guarantee high structure fidelity.
Our sophisticated R2R lamination machines enable you to combine different properties on your materials: foil on foil or paper on foil – in 2 or even 3 layers. This allows the reliable protection of sensitive structures under harsh conditions.
We’ve been print experts for many years, which is why we can offer an extensive range of technologies including gravure, offset and screen printing. These state-of-the-art machines are designed to print inks and pastes with outstanding register accuracy. y.
The expertise gained from our core banknote business enables us to offer customised release and transfer processes, where we separate the underlying substrate from the patterned structure or the functional layer.
We’ve been embedding security features in paper for decades – and that’s why we can offer you the same expertise for your industrial applications. For example, we can incorporate metal tapes in paper for applications where an electrical power supply is needed.
Louisenthal started using a cylinder mould machine for embedding high-definition watermarks in banknote paper in 1969. Today, the process knowhow we’ve built up over more than 50 years, along with our powerful new machines and technologies, enables us to develop specific surface topographies for your industrial applications – whether on paper or on paper-foil laminates.
We offer highly accurate laser cutting for paper patterning in an R2R process – it’s much more precise than traditional die cutting.
To help you select the right process and technologies for your application, our team of experts is on hand with their impressive physical, chemical and engineering know-how. They can also support customer-specific developments and the ramp-up process with a large selection of analysis and measurement tools, including spectrometry, gas chromatography / mass spectrometry, scanning electron microscopy including EDX, and optical as well as laser microscopy.
