India paper

It has a basis weight of 20 pounds (30 g/m2; typical office paper is 80 g/m2), yet bulks 1,000 pages to the inch (390 per centimetre).

[1] It became popular in particular for the printing of Bibles, which could be made relatively small and light while remaining legible.

The 1911 Encyclopædia Britannica boasted, "Printed on thin, but strong opaque India paper, each volume but one inch in thickness."

The process was used particularly by the Oxford University Press and its paper suppliers.

[2][3] India paper has also often been used for the printing of die proofs of postage stamps.
