text: Common roll-to-roll coating processes include:
  * Air knife coating
  * Anilox coater
  * Flexo coater
  * Gap Coating
  ** Knife-over-roll coating
  * Gravure coating
  * Hot melt coating- when the necessary coating viscosity is achieved by temperature rather than solution of the polymers etc.  This method commonly implies slot-die coating above room temperature, but it also is possible to have hot-melt roller coating; hot-melt metering-rod coating, etc.
  * Immersion dip coating
  * Kiss coating
  * Metering rod (Meyer bar) coating
  * Roller coating
  ** Forward roller coating
  ** Reverse roll coating
  * Silk Screen coater
  ** Rotary screen
  *Slot Die coating - Slot die coating was originally developed in the 1950s. Slot die coating has a low operational cost and is an easily scaled processing technique for depositing thin and uniform films rapidly, while minimizing material waste. Slot die coating technology is used to deposit a variety of liquid chemistries onto substrates of various materials such as glass, metal, and polymers by precisely metering the process fluid and dispensing it at a controlled rate while the coating die is precisely moved relative to the substrate. The complex inner geometry of conventional slot dies require machining or can be accomplished with 3-D printing.
  *Extrusion coating - generally high pressure, often high temperature, and with the web travelling much faster than the speed of the extruded polymer
  **Curtain coating- low viscosity, with the slot vertically above the web and a gap between slot-die and web.
  ** Slide coating- bead coating with an angled slide between the slot-die and the bead. Commonly used for multilayer coating in the photographic industry.
  ** Slot die bead coating- typically with the web backed by a roller and a very small gap between slot-die and web.
  ** Tensioned-web slot-die coating- with no backing for the web.
  * Inkjet printing
  * Lithography
  * Flexography
