The Roll-to-Roll Method

Roll-to-Roll is a popular method for volume fabrication on flexible materials; metal, paper, polymers, which include thin glass.

Traditionally nanoimprint lithography (NIL) is derived from a quartz or glass wafer plate-against-plate process technology.

At Stensborg, we have developed our own unique and patented nip moulding process (HoloPrint®), designed for nanoimprinting on transparent as well as opaque materials. This approach works to avoid costly and undesirable web coatings.

The Roll-to-Roll machine typically employing several rollers, has various coating techniques; dip coating, knife-over-edge coating, slot-die coating, direct- and micro-gravure coating, inkjet and spray coating.

The advantages of Stensborg’s Roll-to-Roll NIL: 

  • In-line partial register nanoimprinting.

  • High-cost savings due to a partial layout of an active nanoimprint area. 

  • Reduced manufacturing process due to a high yield. 

  • Agile technology; sustaining pressure uniformity and successful demolding in large-size imprinting areas. 

  • Positive environmental impact due to the speed of production and less energy consumption.


The benefits listed above are exclusive to Stensborg’s Roll-to-Roll NIL offering.

Stensborg’s Solutions to Roll-to-Roll

vs Roll-to-Plate  


The Roll-to-Roll process we offer is fast and scalable. Our Roll-to-Roll machines routinely produce nanoimprints at speeds of up to 50 meters per minute. Due to this scalability, our R2R NIL process is cost-effective. The challenges can be a higher initial setup and complexities when running multiple processes.

The Roll-to-Plate process we offer is better suited for the production of non-flexible substrates, e.g. glass and quartz. It is a prefered method for multiprocessing steps that might involve vacuum sputtering or other process requirements that can not be integrated into the R2R setup we provide.


It is also a preferred method for prototyping optical masters, e.g. the Stensborg Desktop R2P NanoImprinter, as our solution allows the production of smaller quantities, lowering the time consumption while minimising waste.
