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
