web
Paper on, or as it comes from, the papermaking
machine in its full width, or from a roll of paper
in any converting operation. The expression "in
the direction of the web" means in the direction
of the run of the papermaking machine when the
paper is being made. It also means the direction
in which the greater proportion of the paper
fibers are oriented, i.e., the grain (machine
direction) of the paper. The direction of the web
is important in work printed to register, as paper
stretches more across the web than in the
direction of it.
