The next popular mounting board is foamboard, essentially a polystyrene or polyurethane filling sandwiched inside and between two sheets of white clay-coated paper. Again, this method of permanent mounting is only suitable for non-valuable, inexpensive, open-edition, disposable art. This smoothness is very important because it allows paper art such as prints and photos to be smoothly wet-mounted with a vacuum press. It is the most popular because it is the cheapest as well as being strong, easy to cut, durable and quite smooth. Commercially speaking, the most popular one is the 3mm thick, 2440x1220 mm M.D.F. He mount board itself comes in various thicknesses, is manufactured from several different materials and is called various names. The various method of mounting are more fully discussed in the page Picture Framing and Mounting but suffice to say that permanent mounting is only recommended for inexpensive, commercial, disposable art and not for valuable art. This expansion and contraction can cause cockling, and the cockles are those funny looking bubbles one sometime sees in cheaply framed posters at the Sunday markets. If only taping or hinging are used, the artwork expand and contract with the rise and fall of temperature and humidity. Generally picture framers prefer to either wet and dry-mount ( again, not for valuable art ) because these two methods are durable, permanent and allow for straight, flat and smooth surfaces. The mounting can be done a variety of ways. It is mostly called a mount board because the artwork gets mounted onto it. The next component is the Mount Board, or the part that rarely gets seen. Once cut the mat is usually tacked with PVA glue ( some framer use double-sided tape but the tack tends to age and fail after a couple of years ) and glued the mount board, or backing board. The window mat if basically a piece of board with a square or rectangular hole in the centre of it for the picture, or the artwork. People who are not picture framers, or in the trade, often call the mat a surround, a border or a board, but what they mean is, of course, the window mat. The window mat, or simply the mat, usually rests on top of the artwork ( or what is being framed, a photo, print, or what have you ) and surrounds it. Referring to the schematic diagram, most Customers are very familiar with a picture frame and its glass, so there’s not much new, or hidden, to reveal.īut then it starts to get interesting with the next component, the window mat, as we call it here in Australia, or window mount as UK picture framers call it, or passé-partout as it is called Europe. Now, and because everyone asks the question " What’s inside a picture frame" differently, we thought an illustrated exploded view, shown below, would help to answer this rather technical question. The reason this question gets asked is because people know that a thin piece of paper like a poster can’t hold up by itself and wonder what and how it is being held up or supported inside the frame.īut what and how does this is hidden, not visible, and here’s this post to throw some light on the subject, so to speak. We may get asked:“What do you put at the back?”, or: “What will you put my picture on?” and even: “Will you make something so that my picture won’t fall off?”, and so on and so forth. And this is because they are curious of the components of a frame and the names of the parts of a picture frame. The wordin g of the question can change from person to person but Customers want to know the same thing. Yes, " What’s inside a picture frame? is one of the questions we get asked fairly frequently.
