In papermaking, coating is a finishing operation where the surface of the paper is covered to impart a desired finish, texture or property. These coatings provide a smooth surface and can enhance ink absorbency, whiteness, gloss, and paper strength.

Coatings are typically comprised of pigments (including refined clay, titanium dioxide or calcium carbonate) and binders (natural or synthetic, depending on the need for water resistance). Coating can be applied to one or both sides of the paper, and can negatively affect surface quality is the process goes wrong in some way.

Inspection of the surface prior to coating ensures the process is not used on a substandard substrate, incurring unnecessary expense and waste. Monitoring during the process can also detect any problems introduced by the application of the coating, supporting product quality control.
