A stain results when water or other liquids, oils, dirt,
etc. are either spilled or ground into the poster.
Stains are normally the result of accident spills, mishandling,
improper storage or, in some cases, intentional or accident misuse or abuse.
Stains that are present on the border
of a poster do not impact the value. However, if the stains occur on the
artwork of the poster, they are considered serious blemishes and will severely
affect the poster's value. Stains that are found on the back of the poster
are not considered a defect, unless they result in a bleed-through
or see-through that can be seen on the front of the poster. SEE GRADING
FOR MORE INFORMATION!
Water stains and some other liquid and/or chemical stains
can be removed by bleaching/washing the poster. However, this process is
extremely delicate and precise because it involves dampening the poster.
Because paper is very susceptible when wet, this process MUST BE DONE BY
A PROFESSIONAL RESTORER.
Some direct stains can be removed by a damp cloth, carefully
applied to the poster. Posters with stubborn dirt stains should be taken
to a professional restorer where different chemicals can be used to clean
the poster.
If there is an ink stain, such as that from an older
fountain pen, an ink eradicator can be used to remove the stain. Ink eradicator
is a type of bleach, so when the stain is removed, so is the color on the
poster. The area where the ink eradicator is applied would have to be colored
in.
If the stain is the result of indelible ink or newer
ballpoint pens, it cannot be bleached out. THESE STAINS WOULD HAVE TO BE
REMOVED BY A PROFESSIONAL RESTORER.
Pencil stains can be removed with the use of a yellow
brick art gum eraser. The art gum eraser is very soft and crumbly. Regular
pen and pencil erasers will not only remove the stain, it will also remove
all color. A REGULAR PEN OR PENCIL ERASER SHOULD NEVER BE USED TO REMOVE
ANY TYPE OF stains.
Since removing stains from the artwork of a poster almost
always results in the loss of color, IT IS HIGHLY RECOMMENDED THAT THE REMOVAL
OF SUCH STAINS BY DONE BY A PROFESSIONAL POSTER RESTORER ONLY.
For this type of procedure, be sure to have
a good restorer:
