Reddish-brown spots are known as "foxing", caused by mold or the deterioration of the metallic impurities left in the paper from the manufacturing process. Other colors of spots may be one of many types of mold damage. Mold spores are everywhere in the environment, and mold thrives on cellulosic materials, especially in conditions of high humidity (above 65% of relative humidity). Keeping artworks out of high humidity areas like bathrooms devilclipart or exterior walls, can help reduce the development of such stains. If I have a work of art on paper that appears to not be flat, should I be concerned? Paper is hygroscopic, reacting to changes in climate by expanding when it is humid and contracting when it is dry. A gentle undulation in the paper called "cockling" occurs under these conditions, especially with larger works. This may impair the work aesthetically as well as cause mediums such as gouache to crack or flake as it is unable to expand and contract as the paper itself does.
