Ralph, I find your definitions of mount, mat, and backing boards to be confusing. A mount board is the board on which one might mount or attach a work of art (in our case that would be a photograph). That attachment can be done by dry mounting with heat and a dry mount tissue, by using overlapping corners, or some other kind of adhesive. When done the mount board is underneath or behind the work of art and gives the work of art stability. A mat board is a board that is placed in front of, or on top of, the work of art to separate the work of art from the glass or plexiglas used in a frame. In order to see the work of art through the mat board, one must cut a window hole. Thus these boards are sometimes called window mats or overmats. Mats are sometimes used by people even though they are not framing the work of art, just to prevent the artwork from being abraded by another mount board in a stack. Backing board is the material used to fill up a frame behind the mount board. Its purpose is to take up space in a frame so that the work of art and its mount board do not move around within the frame. The confusion for many people is that the board that is used for all three of these functions can be the same board. Some manufacturers of this type of board refer to it as mount board, others call it mat board, and still others refer to it as museum board. If one is looking for a lasting presentation (archival), then one must use a good quality board. This board can be purchased cut to size or in large sheets which one must then cut. Two popular types of board used by photographers in the U.S. are Westminster Museum board and Rising Museum board I believe if you use these terms as I have described them, you will avoid confusing your readers.
