Copy paper is used for copying and

basis weight
is 70-90 g/m

(approximately 18-24 lb) and ISO brightness 80-96%. It is made of 90?100% virgin chemical
pulp
or 100%
deinked pulp
with total
pigment
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 is also called
electronic printing paper
. The basis weight is 40-400 g/m

This paper quality may be either
coated
or uncoated. The demands of the paper may vary substantially depending on printing method:
electrical charge
,
thermal
, magnetic or
ink-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 uniform
porosity
to counteract spreading of the
ink
.
