You can't see it but it is important
We carry 2 types of backs and multiple material alternatives, Their
use is primarily determined by the type of frame, size of the art and
your price and marketing objectives. Pulp board: A white or black paper material. It is .040 to
.090 thick (standard mat board is about .055 thick as a comparison).
The least expensive backing we have,
Paper-based backing is best used with smaller prints-11 x 14 and
smaller.
Backing Board In Picture Framing
You can purchase 2 types of backing. First is backs without
hangers attached and second is with hangers attached. With the
first you would back items not immediately going into a frame or to be
used with a traditional frame that already has a hanger system..Â
The second, backs with hangers attached, are used with frames that do
not use traditional hangers that are screwed into the frame and hold
wire for hanging the framed piece or some other hanging hardware
attached to the frame itself. Backs with hangers attached offer a
simple and inexpensive solution.
Backs without hardware come in 4 general categories:
Foam Core: Inert, foam plastic center with paper on both sides.
Excellent for framing and a standard for most frame shops. It is a bit
thicker than mat board, has a very clean appearance and communicates
"good quality" for a few cents more than paper-based board. Standard
foam core board was originally used in silk screen industry. Foam core
comes in multiple grades: Archival Cotton covered foam core, archival
paper covered foam core, acid-free foam core and economy foam core.
Foam core comes in white or black. It also comes in "self-adhesive"
with a tear-off cover sheet that exposes
pre-applied adhesive for mounting prints. Foam core is available in
1/8" and 3/16" thicknesses. The 1/8" is the same weight as 3/16. It is
more dense
Mat Board can also be used as a backing. Works well when you are
going to "float" your print on the back. When you float a print, the
window of the mat is larger than the print rather than smaller. The
print is attached to the
mat board and some of the mat board surrounding the print is visible
through the mat window. Mat board as a backing, however, is more
expensive than paper-based backing or foam core and does not have the
rigidity of foam core.
Cardboard is sometimes used as a backing. We do not sell it and
do not recommend it. It is usually too thick, is highly acidic and is
bad marketing. It communicates a "cheap" product rather than an
inexpensive one.
There are various other specialized boards that have been produced for
photography or graphic design industries. They are sometimes used in
framing but are not really a factor. Stick to paper based backing, foam
core or mat board for most uses
