What’s the difference between coated paper and a coating finish?

Coated paper is produced at the paper mill with a smooth surface. Coated stocks have a range of reflectivity values including dull, matte, silk, satin or glossy.

A coating finish on the other hand is produced at the printing company. It’s a clear layer applied after the ink is printed. It enhances the visual appeal of printed graphics. Coatings also add various levels of durability, shine, and protection to the printed surface.
