two-sided sheet
A term used with reference to the difference in
shade and/or texture between the felt and wire
sides of a sheet of paper. The term is generally
applied to dyed papers, and usually refers to a
difference in the depth of color, with the felt
side being darker and the wire side lighter.
Two-sidedness in paper may also be produced by
using a mixed furnish, e.g., long- and
short-fibered stock, the short fibers (as they are
lighter) being on the top or felt side and the
long fibers on the bottom or wire side. Another
form of the two-sided sheet is the filled paper,
in which more pigment is retained on the top side
of the sheet. (17 ,
