These are often used for letterhead or any type of form that needs to be filled out. This type of sheet is also often used to create a “natural” or “earthy” printed look.

Most book and text weight stocks are COATED sheets. See www.clearprint.com/articles/printing/difference-coated-uncoated-paper for more information on coated vs. uncoated sheets.
