If a watermark is present, the watermark should be viewable, correctly oriented with the lettering right side up. Text is for applications that are more important, where quality has priority over cost. These are premium papers. Text refers to the deeply textured look and feel of the paper. Not all text papers have textured surfaces.
Smooth surfaces are also available.
Uncoated book, also called offset, is available in a large number of forms. Many applications are cost constrained so it is generally used in lighter stocks compared to text papers. Coated book is for the best reproductions where quality and color accuracy are important. Coated book is made from a base sheet of uncoated book. One or both surfaces can have a coating.
