The process of preserving works of art from loss,
damage, or neglect.
at POSTER MOUNTAIN strive to meet the goals of the client while staying
true to the nature and beauty of the artwork. All techniques and
processes used by our conservators are completely reversible. We assume
that at some point the craft will evolve, new conservatorial
techniques will be discovered, or due to age and mis-handling, the
conservation work we are doing today will need to be un-done, or
re-done at some point in the future. It is for this reason that we use
easily reversible pastes, and strong, yet penetrable backing materials
to help ease future re-conservation efforts.
or rehydration, helps to cleanse away adulterants, contaminants and
surface dirt. When warranted a rinse with an appropriate carbonate will
help to provide a buffer and and keep the naturally occurring
acids inherent in modern, machine made paper at non-detrimental levels
for many years.
Linen backing and paper
backing are the two most commonly used techniques in modern poster
or museum mounting is the preferred method for large libraries and
archives in which the posters will be handled and stored professionally
in climate controlled environments, such as the ACADEMY OF MOTION
PICTURES ARTS AND SCIENCES library and UNIVERSAL STUDIOS poster
archives, (both accounts are serviced exclusively by POSTER MOUNTAIN).
Museum mounting is a very delicate mount, very easy to un-do, and
must be handled with extreme care.
is actually a misnomer, as most conservators use a cotton canvas rather
than actual linen.
A comparatively durable mount, linen
backed posters are more resistant to improper storage or rough handling.
be rolled for easier transport and are suitable for framing,
making this the ideal mount for the collector market, where
items change hands constantly and are frequently shipped
around the world.
Gelatin re-sizing is
unique process invented, and used exclusively, by POSTER MOUNTAIN. This
process allows for posters to be conserved and restored without a
traditional backing. It is ideal for thick stock paper and also
has applications in strengthening badly damaged paper items, such as
those damaged by mold.
use only the finest cotton canvas available, grade
"A", 12oz., raw, unbleached canvas imported from India to create a
laminate mount with a white, machine-made Japanese paper called MASA,
which is sandwiched between the poster and the canvas. This additonal
layer helps to
give the mount more body, while also providing a smooth surface for the
our paper mounts we use a hand made, long fibered, Japanese mulberry
paper called OKAWARA.
Pastes and Adhesives:
are constantly researching new techniques and
procedures, including the use of synthetic pastes, and paste
combinations. The combinations we employ varies depending
on the job at hand.
Natural Starch: Popular amongst conservators
for decades, Rice and Wheat pastes alone have stood the test of time.
However, these organic pastes can often attract molds, mildews and
insects, and can yellow with age. Adulterants, added to prevent molds
from culturing and to make them less attractive to insects, are
generally acidic compounds which will have a harmful effect on the
poster over time. The old paste can become so thin as to permeate
deep into the fibers of the poster, causing the piece to lose it's
structural integrity and make it more susceptible to damage during
the demounting process.
Synthetic: A very wide
range of water-soluble, synthetic, starch-based pastes are available to
the modern conservator. Some of these pastes are considered to be
archival. They will not yellow over time and they remain soluble in
water, but will not break down completely, making the clean up of old
mounting paste much less dangerous to the artwork. Currently, we
use proprietary mixtures of wheat paste, synthetic
pastes, methyl cellulose, and PVA (Poly Vinyl Acetate) depending on the
specific nature of the job at hand.
and handling is
paramount to maintaining and preserving your posters. Humidity,
temperature, and UV exposure are all factors that must be controlled.
Most collectors want to display and enjoy their collections, but in the
case of posters, environmental conditions must be controlled in order
to properly preserve them.
