Handmade- and the better machine-made papers dried
in a current of air, either at normal or elevated
temperatures, as distinguished from paper which is
dried by contact with heated rolls. This method of
drying reduces stresses, including DRIED-IN STRAIN ,
which are imposed on paper while drying, because
the sheet is allowed to dry, and therefore
contract, at a slower rate. See also: ANISOTROPIC BEHAVIOR .
