Hi Tom,
If you are using a fairly high grade of acrylic, which for that
price I'm sure you are, you don't need the matting to act as a spacer, it really
doesn't anyway, as the piece is so large, it touches all over the middle and by
using the matting, it leaves that little bit of space in front of the poster
that can cause the poster to warp into that space. Matting is typically just for
decoration, except when you are using glass and only if effective as a spacer
for very small pieces. My advice would be to just frame it. Sandwich it between
the acrylic and the foamcore backing, use at least a 4" wide solid wood frame,
put L brackets on the back corners of the frame and then build a back frame out
of stretcher bar wood to act as a brace. In fact, your wood frame really becomes
just border as you put the hanging brackets on the back piece of wood. That is
where all the load of the weight should be. If you do it properly, it isn't as
much work as one would think. For instance, say you build a wood square out of 2
1/2" - 3" wide wood that is about 3/4" - 1"deep. Now that you have
a square, put some straight pieces of the same wood from top to bottom and
side to side to make that square sturdy. That becomes your back frame. Now, you
see that you need a front frame that is at least wide enough on the side to
cover the sides of that back frame. That's about it. Build the front frame, lay
the plexiglass, poster and acid free foamcore backing into it, then place the
back frame on top of all that and either nail it to the front frame or
better yet, use brackets like you would use to hold an oil painting in a
frame. Just put a lot of them all the way around. Then use heavy duty
strapping hangers, pointing upward (no wire, creates too much load on the
side legs), use heavy duty anchor hangers for the wall and you are
ready to go. Please feel free to have your framer call me with any
questions. Many of my customers around the country that order their framing from
me, and know I can't ship 3 sheet frames, just have their framers call me and I
give them the scoop. Maybe you will send us some pictures when it is all done.
Good luck Tom.
Sue
