    The main atmospheric component in the conditioning of paper is relative humidity which determines moisture content. This moisture acting as a plasticizer affects strength, rigidity, and plasticity. Changes in moisture content produce dimensional changes in the fibers which in turn are translated into over-all dimensional changes in the sheet. Examples are given showing the importance of relative humidity in testing, specification, converting, and end use. Other conditioning and weathering factors are discussed.
