  PAPER TYPES (II)  
     
 

COATED BOOK papers are free sheet papers specified for magazines, catalogs, calendars, and posters-- anything in which reproduction quality requirements are high. Coated papers reproduce much finer halftone screens with sharper definition, better density, and greater color fidelity than uncoated papers.

The coatings cause ink to dry on the surface of the paper instead of being absorbed into the fibers. This is called "ink holdout," and it makes for brighter colors and sharper photos. Coated paper finishes run from dull to very glossy, have a greater affinity for printing inks, greater smoothness, higher opacity, and better ink holdout than coated papers. The ratio of stock to coating in a typical North American coated paper is 70:30.

DRAWBACKS to using coated papers stem from the fact that they're generally harder to make, print, bind, and recycle than uncoated papers. Gloss-coated papers (as opposed to matte or dull) produce glare and eyestrain. Bits of coating that pull away from the paper surface can cause hickeys. Coatings can crack when folded. They can interfere with binding glues. They are difficult to extract and dispose of during recycling.

COVER papers are heavy, durable papers for the outer covers of books and catalogs. They can also be used for postcards, presentation folders, and other jobs that need to be made of heavyweight paper. Paper mills very often match cover papers to their bond, text, and book papers to make it easier for designers to specify them.

Not all covers are made from cover papers, however: the cover of a magazine or a catalog could be any paper that's sturdier than the inside pages. When a publication's cover is printed on the same paper as the inside pages, the publication is said to be a "self- cover."
