Definition:

Paper which has had the acid removed from the pulp so that it has a neutral 7.0 pH (or above) is known as acid free paper.

The acid normally in paper can discolor it over time and turn it brittle. Photos printed on papers with acid will be altered and can fade and even eventually disintegrate. Paints and items that come into contact with the acid paper such as photos in photo albums or items in a collage will have a shortened life.

When to Use Acid Free Paper in Desktop Publishing

The use of acid free paper can prolong the life of a document or project printed on, painted on, or attached to the paper. For preservation and long life, use papers specifically labeled as acid free. For the best preservation, all materials including inks, glues, fabrics, and bindings used in a project should also be acid free.

Many desktop publishing projects are designed to have a relatively short life because they are frequently replaced with newer versions — such as brochures, price lists, newsletters, sales fliers, or party invitations. Using acid free papers is not usually necessarily. However, for projects that are likely to be preserved or business documents that need to be archived for many years consider using acid free papers. A few typical desktop publishing projects where acid free or archival paper is common include:
