Printing and writing paper

Printing and writing papers are paper grades used for newspapers, magazines, catalogs, books, notebooks, commercial printing, business forms, stationeries, copying and digital printing. About 1/3 of the total pulp and paper marked (in 2000) is printing and writing papers.[1] The pulp or fibers used in printing and writing papers are extracted from wood using a chemical or mechanical process.

In the United States printing and writing papers are separated into four main categories:[2]

  1. Uncoated Freesheet Paper
  2. Uncoated Mechanical Paper
  3. Coated Freesheet Paper
  4. Coated Mechanical Paper
