Cast Coated - What does cast coated mean?

Answer:

A method of coating paper; a liquid coating is deposited onto the web, which is then pressed against the surface of a heated, highly polished metal cylinder or drum (usually made of chromium). The heat and pressure cause the coating to dry and, as it hardens and sets against the cylinder, it takes on a highly smooth and glossy finish; cast coated paper has the highest gloss finish of all coated papers. It is also a thicker paper and has excellent ink absorbency.
