Acrylic, backing boards and 4 colors or 100% cotton mountboards are all available in the sizes you need.

Can you do it that size.

My largest frame I can cut is 1500mm due to size of workshop so any larger I would have to order already cut and joined.

Largest mount I can cut is 1200mm due to size of mountcutter.

At that size I wouldn't use glass so it would need to be acrylic, 4mm might be thick enough although I have only done up to 1500mm x 1500mm.

The frame will need to be very robust to take the weight of everything, at that size I would probably make a sub-frame to hold everything and then just have a cosmetic frame over the top.

Make sure you cost everything well so you don't end up losing money on the job.

I agree with prospero about the mount and I will leave it to him to suggest alternatives.

I've recently completed a couple of frames a little larger than the one you are making. Both were stacked frames so quite strong. However, I made sub frames for both and found 3mm acrylic thick enough, cut to size by a local company. I would suggest getting the acrylic cut before you make the frame to be on the safe side.

OK....

If the customer wants the mounted 'look', create this by using a wide, flat moulding painted whatever colour.

The poster itself can be laid on a bed of spliced foamcore - in two layers so that the splices don't coincide.
This board shold be a certain amount bigger all round than the poster. Use a slip as a spacer for the glazing,
maybe 30mm wide. If you use a board 20mm bigger all round than the poster so as to give a 10mm overlap
onto the poster. These dimensions can be fine-tuned.
The main thing is to elevate the back of the slip with a strip of linen tape about 10mm wide. So there is a gap
of 10mm to allow for expansion of the poster. The poster itself should be hinged at the top with a few loose hinges
on the side/bottom to stop it flopping about.
The idea is that the edges of the poster are not restricted. Without a mount you are free to use a quite wide frame
which is desirable with a frame of this size. :wink:
