Coated paper is covered with a thin layer of minerals (kaolin, carbonate, etc.) which gives it a smooth and uniform appearance. It provides accurate color and detail rendering, ideal for rich visuals or flat areas.
Uncoated paper, which is more raw and porous, absorbs ink more. It has a natural, often matte, touch and is suitable for textual media or for a more artisanal aesthetic.
Use case: For a corporate booklet, the inner pages were printed on uncoated paper for comfortable reading and a textured finish, while the cover was made of coated paper with a lamination finish to guarantee contrast and protection during handling.
