The
process of hand making paper in Europe and in the Americas is not too different
than how the Japanese and other Oriental peoples have made paper. It shouldn’t
come as a big surprise, because we did borrow the basic technology from the
Chinese. One key difference is that the Europeans used cloth as their raw
material in paper making. In the Far East, on the other hand, paper makers used
the inner bark of various types of plants.

The
other major difference is that the Japanese and other Asian peoples are more
traditional. They had practiced the same method of paper making for centuries –
at least until the 1860s. Why would they change? After all, some of their
papers could last centuries. Japanese mulberry papers can last 500 to 1000 years.

In
the West, we are not so traditional. We have continually tinkered with the
processes with the goal of finding new ways to make paper faster, easier and
sometimes, but not always, better.

Originally,
paper in the Western countries was produced using recycled cloth. During the
early Renaissance in Italy, paper was primarily made of linen. Hemp and cotton
was also used to a much lesser extent. These materials were first cut up into
very little pieces, soaked in water and then beaten to a pulp. After the cloth
pieces were reduced to fibers, the slurry was scooped up in a frame with a
screen, which allowed the water to drain off leaving a sheet of fibers. The
sheets were then stacked, pressed and then dried. The original method that the
Italians used was very similar to the way that the Chinese and Japanese made
paper.

In
the West that was not good enough. After Gutenberg invented movable metal type,
our printers had more orders to fill. Beating on the raw material with wooden
bats or mallets was not going to meet production quotas. That necessity was the
mother of the mechanization of the paper making process. Stampers powered by
water wheels beat the rag fibers to a pulp faster than any man could.

Then
in 1680 the Hollander beater was invented. Unlike stampers that utilized a waterwheel for power, the
Hollander beater was powered by the wind. This machine featured teeth that chewed up the tiny pieces of rags into pulp in a matter of
hours, faster than the stampers could produce. In fact, the Hollander beater increased production by approximately 800%.

This
improvement in output did, however, come at a slight cost in quality. Fibers
beaten with the stampers were relatively intact. On the other hand, Hollander
beater shredded the fibers into much smaller pieces. The resulting sheet was a
little softer, which was great for letterpress and woodcut. However, the paper has
lost some of its strength. That’s the price of progress.

After
the pulp is processed in the beater, it is mixed into a vat of water. The
fibers floating in the vat are then scooped up in a paper mold, which consists
of a wire screen mounted in a frame. The deckle, which covers the edge of the
frame, acts as a dam preventing the water and cloth fibers from spilling over
the edges. As the water drains through the screen, the frame is shaken from
front to back and from side to side. Shaking in two directions is an important
procedure because the fibers intertwine as opposed to orienting in a single
direction. A sheet with fibers in one
direction tears very easily with the grain.

After
the water drains through the sheet, the remaining fibers form a sheet and the
deckle is removed from the frame. The wet sheet is then transferred to a felt
layer on top of the sheet stack. Another piece of felt is laid over the sheet.

When
the stack is completed, it placed in a press to squeeze out some of the water
from the sheets of paper. Originally, the type of press that was used was a
screw press. As primitive as this may seem, this type of press is still used in
some places today. Most of these, however, have been replaced with hydraulic
presses.

Traditionally,
the sheets will remain in the press overnight. After pressing, the sheets still
contain a very high water content and must be dried. Drying can be done in a
number of different ways. The wet sheets can be smoothed onto a flat surface to
dry. Or multiple sheets can be stacked and hung to dry. How the sheets are
dried often depends on the ambient temperature and humidity in the shop. The
rate at which the paper dries is critical. If the sheet dries too fast, it
could cockle. Cockling is a deformation in the paper. Once this occurs in a
sheet, it is irreversible.

For
relief printing, generally you will want a sheet, which has no sizing. This
type of paper is referred to as “waterleaf”. For other artistic applications,
such as calligraphy, a much harder, smoother and less absorbent sheet is
desired.

To
prevent the fibers of the paper from absorbing ink resulting in bleed, size is
often added to the paper. As early as the Renaissance, gelatin was used as a
size. After the paper is dried, it can be dipped in gelatin, pressed (squeezing
out the excess) and dried again. In some cases, sizing is added in the beater
as the bits of rag are being ground up.

For
woodcut and linocut printing, handmade papers from manufacturers in France,
England and the United States are excellent choices. Ideally, you want source a
paper with linen or cotton fibers; neutral pH (acid free); no chlorine
bleaching (chlorine deteriorates the fibers); no sizing and a paper weight in
the range of 240 gsm. Of course, you could always make your own paper. Start
saving your old, white cotton tee-shirts.
