of print presentation are far
superior to the old way Of
paste pot mounting.
It used to be that photo
graphic prints were just stuck
on their mounts with a dab
Of glue or paste but we have
long since learned that such
adhesives eventually viii cause
stains that permanently dam
age photographs. Even at the
best, Clues and pastes may only
be considered as temporary
adhesives which eventually re-
linquish their grip and allow
the print to detach.
In these enlightened days,
photographers employ dry
mounting tissue which forms
d permanent bond between
print and mount and which
has no staining or damaging
effects. Rubber cement is still
an effective substance for print
mounting for temporary jobs
but will eventually dry up and
allow the print to slip of the
mount.
Picture Must Be Flat
No matter how the picture is
to be attached to its mount it
will be necessary to have it
perfectly flat. In the normal
course Of drying the print will
curl. In this condition, it will
give considerable trouble when
we attempt to make it lie fat
during the mounting opera
ton. To correct for this,
dampen the emulsion side of
the pictures and place them
face to face under a heavy
weight for about "a hours.
Two sheets of smoothly fin
ished plywood, larger than the
prints, will serve the purpose
If you don't own a print
Strengthening press. After the
prints are in position between
the boards place some heavy
object on the top and when
you return a day later your
prints will he flat and roodv
for mounting.
IF a temporary job will be
satisfactory, you can try the
7 rubber cement as your adhe-
sive. First trim the print care
fully to its final size. Then
place it on the mount and
trace an outline of the print
after moving it about until the
margins are correctly spaced.
The pencil lines will help you
get the print accurately spaced
after the adhesive has been
applied. Now apply a thin
coat of the rubber cement to
the back of the print being
particular about getting it
clear to the extreme edges.
Then apply another thin coat
Of the cement to the area Of the
mount where the print will be
placed. Again, be sure that
the cement covers the entire
print area. It will make no
difference II it runs over the
pencil lines for it can be easily
removed later.
After the rubber cement has
dried on both mount and pic
ture, you will De ready to fix
the print. Never attempt this
while the cement is wet. Hold
the print with both hands so
that it does not touch the
mount except at the top pencil
line. Allow it to touch there
only after the top of the print
and sides are properly aligned.
After the print is in position,
run a soft cloth over its face
with q gentle pressure to in
sure an overall bond. Excess
rubber cement at the edges
can be easily rubbed OF.
Dry Mounting Tissue
For a permanent, mounting
Job. use dry mounting tissue.
This is a thinly coated tissue
which becomes tacky on both
sides. on the application of
heat, Although the profess
SIGNALS use a dry mounting
press. we can get along with
an ordinary hatiron. To be-
gin, place the print face down
on a table and apply a sheet
Of the tissue to the back so
that it covers the entire sur
face. Then take the hot iron
and run the tip over the It's
sue for a short distance just
enough to tack the tissue in
place. Now trim the print
along all four edges and you
are ready for the next step.
Place the print face up On the
mount and move it about UNI
til the margins are exactly
spaced. Then tack the print
in its final position by lifting
the corners of the print and
touching the tissue with the
tip Of the iron so that the It's
sue adheres to the mount at
these points.
Lay q sheet Of brown wrap
ping paper over the face Of
the print to prevent scorching
and pass the hot iron slowly
over the surface. The heat
transmitted from the iron viii
cause the tissue to adhere to
both print and mount for a
permanent bond. Now re-
move the paper and with a
soft cloth, apply gentle pres
sure to the print working from
the center toward the edges.
This should be done, of course,
while the print is still hot from
the iron. Lastly, test the bond
by slightly bending the mount.
IF the edges pop loose it will
