Paper is defined internationally as a thin layer of mostly cellulosic plant fibers, produced on a screen by dewatering a slurry of fibers in water . The slurry is called pulp. Despite recent developments (proteinic or synthetic fibers, chemical additives, coating, etc.) the “cellulosic plant fiber” will be the main, not exclusive, component of...

The application of (usually white)...
Requirements of Coated Papers for the Printing Process Printed matters are used for advertising, news and information, transactions, edu¬cation, and entertainment.
