The Method of Roll-to-Roll
Roll-to-Roll is a common volume fabrication method for flexible materials such as metal, paper, and polymers, including thin glass.
Roll to roll manufacturing
Nanoimprint lithography (NIL) is traditionally based on a quartz or glass wafer plate-against-plate process.
Dip coating, knife-over-edge coating, slot-die coating, direct- and micro-gravure coating, inkjet and spray coating are some of the coating techniques used by Roll-to-Roll machines.
Our Roll-to-Roll process is both fast and scalable. At speeds of up to 50 meters per minute, our Roll-to-Roll machines manufacture nanoimprints on a regular basis. Our R2R NIL method is cost-effective due to its scalability. The difficulties can include a longer initial setup time and increased complexities when running several processes.
Non-flexible substrates, such as glass and quartz, are ideally suited to the Roll-to-Plate process we sell. It’s the preferred approach for multiprocessing steps involving vacuum sputtering or other process conditions that can’t be accommodated by the R2R setup.

Roll-to-roll processing, also known as web processing and reel-to-reel processing or R2R in the field of electronic devices, is the method of making electronic devices on a roll of flexible plastic, metal foil, or flexible glass. It can refer to any method of applying coatings, printing, or conducting other processes beginning with a roll of a flexible material and re-reeling after the process to produce an output roll in other fields prior to this use. These and other methods, such as sheeting, may all be grouped under the umbrella term “converting.” After the rolls of material have been coated, laminated, or printed, a slitter rewinder may slit them to their final size.
What is roll-to-roll processing? what
For the creation of human-device interfaces and unperceivable skin-contact personal health monitoring systems, thin and compliant conductive materials and electronic devices that can stand as free-standing membranes or conform to surfaces are essential. A roll-to-roll (R2R) method for preparing conductive polymer nanosheets on wide areas has been built in this work, with the aim of moving this technology closer to real-world applications. R2R conductive nanosheets are created as free-standing structures by releasing them from a temporary substrate and then applying them in conformal contact to any target surface with any shape, curvature, or surface topography (including biological tissue such as skin). By using butylene glycol (BG) as a dopant, a dermatologically approved ingredient, a particular high-conductivity formulation of PEDOT:PSS has been optimized for skin-contact applications. The R2R nanosheets were put to the test as non-perceptible surface electromyography electrodes that could monitor muscle activity. The current R2R process has many advantages, including continuous, high throughput printing on wide area rolls, cost-effectiveness, execution speed, and the use of industry-ready/mass-scale manufacturing technology.
