Dry Mount Problem

[Dan Smith]

With respect to hinge mounting, you will get more protection of the image from pollutants migrating in from the back of the print if you dry mount. Bainbridge Alpharag Artcare boards have an active 'trapping' system which protects the print from pollutants from the front as well as back but some testing has shown dry mounted prints do better than those not dry mounted. They also lay flat and don't get wavy with atmospheric pressure & moisture changes.

Many Thanks to everyone for their help. I tried Jeff White's suggestion of using steam from a kettle and it worked like a dream. Many many Jeff!
