Industrywide standard definitions do not exist, but most papers fall into one of five general categories: • BOOK: general-purpose papers for catalogs, magazines, direct mail, and many other kinds of commercial and publication printing. • WRITING: used mainly for stationery. • COVER: thick, heavy stocks for the covers of booklets, manuals, etc. • BRISTOL: thick, stiff papers for business cards, file folders, and other items requiring a durable stock. • OTHER: papers that do not fit under any of the first four headings, such as onionskin, carbonless duplicating papers, etc. Assigning quality levels to paper is also arbitrary, but the following designations are generally accepted: • The numbers 1 through 5 denote quality grades for coated papers, with #1 being the highest. Coated #1, #2, and #3 papers are free sheets. Coated #4 papers include free sheets and groundwoods. Coated #5 papers are groundwoods. The choice depends on the degree of print quality required. For example, a magazine might use a #2 or #3 sheet for its cover and a #4 or #5 paper for the inside pages. • Other kinds of paper are quality-graded with letters, numbers, and words such as "premium" and "super-premium." Again, no standard terminology exists. Paper is sold by weight in the "basic size" for its grade. The basic sizes for the four most common grades are: • BOOK: 25"x38" • WRITING: 17"x22" • COVER: 20"x26" • BRISTOL: 22.5"x28.5" RETURN TO FAST ACCESS MENU RETURN TO SESSION OUTLINE |
