wild
1. An irregular formation of the fibers in a sheet
of paper, resulting in a mottled appearance in the
LOOK-THROUGH of
the sheet, as opposed to a CLOSE FORMATION . It
is caused by: 1) partial clotting or lumping of
the fibers; and 2) high freeness or excessive
vacuum at the first suction box of the papermaking
machine. It is especially noticeable in
long-fibered papers, although it is possible to
imitate a wild formation in paper made up of short
fibers by manipulating the sheet forming
equipment. Also called "cloudy." 2. See: MARBLED GRAIN .
