Adhesive board is the only alternative available to dry-mounting - A professional process where an item is bonded onto a thicker substarate to ensure the item will remain perfectly flat and warp free for ever. There are a lot of items which benefit from Adhesive board, posters which are printed on very thin paper are a good example, as the paper is thin , when the poster is put into a frame the weight of the whole poster is on the bottom so you get a warped effect, if the poster is adhered correctly to adhesive board this will not happen. Notes : The artwork once applied may be damaged on removal from any Adhesive board. The boards are not of archival quality and therefore the board is not suitable for mounting expensive / irreplaceable items.
