• To test for grain direction, dampen a sheet of paper.
It will curl parallel to the grain direction.
• A paper is said to be "grain short" when the fibers
are parallel to the short dimension (edge) of the sheet; "grain long"
when parallel to the long dimension.
• Paper always stretches during printing, but it
stretches more with the grain than against it. Therefore, printers try
to print with the grain parallel to the press cylinders to keep stretch
and misregistration to a minimum.
• In the bindery, it is better to fold with the grain
than against it, since folding against the grain can cause the paper to
