cover papers

A class of papers used for the covers of pamphlets (other than self-covers), catalogs, brochures, or any other stitched publication, to provide protection during handling and (sometimes) to enhance appearance. They are made in white and a wide range of colors. The majority have plain edges; however, they are also available with deckle edges. Cover papers generally have good folding characteristics, and have rough finishes or are embossed with fancy designs. They are usually produced from chemical wood pulps, sometimes in mixtures with mechanical wood pulp, and, although many are made from pulps containing varying amounts of cotton fiber pulps, they have but little permanence. Various coated papers, including plain, heavy, plastic-coated, cast-coated, metallic, and cloth-lined papers are also used. Common basis weights of uncoated cover papers are 50, 65, 80, and 2/65 pounds (20 X 26 - 500), while weights of coated papers are 60, 80, and 100 pounds (20 X 26 - 500). Aside from folding endurance, desired characteristics include dimensional stability, uniformity of printing surface, and durability. (17 , 86 , 139 , 234 )
