if prints are fixed to a backing board, what happens if the owner wants to change the frame (e.g. a bigger frame)?
Ok I suppose this could make it difficult (although not impossible) to change to a larger frame, however the OP has already chosen this method by trying a self adhesive board (which was unsuitable) and he also states his ideal method would be dry mounting, which is outwith his present budget.
Therefore I'm sure this would still be a suitable and affordable solution to his problem.
Or if you wish to hinge mount them, acid free adhesive tape could be purchased from a local framers trade supplier.
I had the same problem a few years ago with customers complaining their 20"x 16" portraits were rippling.
I tried a few different solutions and finally settled with 'Daler Rowney "XTRA TAK" mount board', I have some 6+ year old sample prints which are still perfectly flat, even though they have often been stored in the boot of my car (even during winter).

haha, I'll have to rethink, the masking tape hasn't lasted long (it's only cheap stuff I think)... might have to get branded masking tape or a stronger tape? maybe that brown gum tape..?
Masking tape isn't intended to last long, it's meant to be removed easily after decorating
I use framers tape for affixing photos to the back of mounts.
No it doesn't require wetting, it's just like regular rolled tape. If you didn't require it for tomorrow I'd post you a roll.
