One or both sides of paper is often coated with clay, latex or some other material that affects the absorbency and appearance of the sheet. The coating is applied in different ways during or after the papermaking process. A coated paper with a high-gloss finish known as cast coated paper is created by pressing or casting the still wet coated paper against a polished, hot, metal drum.
Some cast coated papers can be so smooth and shiny that you can see almost mirror-like reflections in the paper. They also hold ink well and produce sharper, brighter images.
