'The meaning of the term - printability'

Calendering in papermaking is a finishing process that involves passing paper between heated rollers to create a smooth, glossy surface and improve its thickness uniformity and surface properties. This process can also enhance the paper's printability and opacity.

Beside wood fiber, Loading or filling material such as clay, CaCO3, Talc, TiO2 etc. are used for higher brightness and better printability. Rosin, alum or combination of other chemicals is used to make paper water resistant.

Some special purpose paper such as coffee filter paper contain wet strength polymer so to withstand hot water soaking.

Colored paper may contain dye or pigment.
