What is a paper watermark?
Watermarks are designs or patterns put into paper during its production,
by making thinner
or thicker the layer of pulp when it is still wet.
Paper watermarks can be seen holding the paper against the light or, in
some cases, over a
black surface. Usually, they show the manufacturers name, and geometric
designs, or images
of animals, etc.
The object of watermarks in paper is, essentially, identifying the
paper, as a signature of the
manufacturer, or as a security measure to avoid forgery of important
documents as bank notes,
passports, entry tickets, etc.
Today, good quality writing paper, as well as art drawing paper or paper
for bibliophile publishing,
usually carry an identifying watermark. Nevertheless, it is easier to
find watermarks in old papers
from envelopes, letters, books... Indeed, watermarks are a good help in
the study of old documents,
as they can suggest their origin or date.
