ledger paper
Originally, a writing paper used for pen and ink
records, as in ledger or blankbooks, but now also
used for printing purposes. Ledger papers are
generally made from cotton fiber, bleached
chemical wood pulps, or mixtures thereof. High
quality ledger papers are animal sized, and the
usual ledger paper is made in basis weights
ranging from 24 to 36 pounds (17 x 22).
As it is subjected to considerable usage, it
requires a high degree of durability and
permanence. Significant properties include
strength, especially tearing resistance,
erasability, water and ink resistance, uniformity
of surface and color, smoothness, and a good
surface for ruling. (17 , 58 , 339 )
