For the most part, all adhesive mounting and dry mounting are non
conservative mounting techniques. T-hinging with acid free tissue and
water soluble adhesive is about the only true conservative mounting
method. I dont go as far as Japanese rice paper and wheat starch, but
Linceo makes some stuff that is reasonably close and good enough if
you are not mounting an original Ansel Adams print. This technique is
also cheap and requires no special equipment. The print, mounting
board, and mat all expand an contract at different rates with
temperature/humidity changes which is why you just attach it in a
couple of points with the hinges. In more extreme cases where even two
mounting points might cause a little buckling you can use one point
top & center and corner mounts assuming your mat overlaps your print
enough to cover the corners and you are not doing a float mount. I
will often just mount the print directly to the mat and then I do not
have to tape the mount board to the mat. This also assumes you are not
float mounting.
