Mounting boards in a variety of standard sizes come in white, black or gray and can be easily cropped to create a border of any desired size, or no border at all. To get a straight, clean edge on prints or mounts, place them on a hard backing such as a pane of glass and cut them with a craft knife guided by a steel straight edge. Prints can be mounted on exhibition boards in a number of ways. for permanence, use dry mounting tissue, a thin, resin based waxy sheet that adheres when heated, because it resists warping and discoloring even under the most humid conditions. Trim the tissue to the same size as the print, put the print face up on the mounting board with the tissue in between, and cover the print with thin card board. Press down firmly on the cardboard with an electric iron set at the temperature for wool. An iron will not give a good result on a print larger than 8 by 10 inches; dry mounting presses are also available to do the job of the iron more simply and efficiently.
If you are working with resin coated printing papers, you will have to obtain a special mounting tissue and temperature control strips to prevent overheating and blistering the print.
You may want to try rubber cement or spray mount, but keep in mind this will eventually discolor the photograph.
