Classification of paper
Special fine paper is a classification ofpaper used forcopying anddigital printing.[1]
Copy paper is used for copying andlaser printers. Thebasis weight is 70-90 g/m2 (approximately 18-24 lb) and ISO brightness 80-96%. It is made of 90–100% virgin chemicalpulp or 100%deinked pulp with totalpigment content of 10-15%. The most important quality is smooth run in a copying machine / printer and good dimensional stability. It must not show curling or cockling, nor may it retain dust.
Digital printing paper
[edit]Digital printing paper is also calledelectronic printing paper. The basis weight is 40-400 g/m2.[citation needed] This paper quality may be eithercoated or uncoated. The demands of the paper may vary substantially depending on printing method:electrical charge,thermal, magnetic orink-jet. All require good dimensional stability, no curling or cockling, good surface strength and surface smoothness. For ink-jet paper it is also important with sufficient and uniformporosity to counteract spreading of theink.
