In the image framing industry, a mat (or mount in English English) is a thin piece of paper material that is included in a photo frame, which serves as an additional decoration and performs several functions others that are more practical, such as separating art from glass. Placing a mat in a frame is called mat , a term which can also be used interchangeably with mat .

Function
Decorations
This frame's framing mat is most commonly known by ordinary people for its use as an additional decoration to enhance the appearance of framed pieces, sometimes along with fillets or more rarely, liners made of wood moldings with fabric surfaces. Although the webbing usually contains only one opening per layer, the mat may not contain if the image is "floating" or "mounted on top" (placed on a mat), and two or more mats exist, more commonly with family photography or member type images individual families than any other type of artwork. Typically mats or mats, if carefully matched and properly proportioned, serve to help draw the eye toward framed pieces, or toward certain key elements of the work. However, while the mat is usually regarded as something to complement or arrange the artwork for the best effect, or not interfere with or compete with it (neutral colored mats are often preferred by high-end art galleries,) there are several examples of mats considered by artists as part of artworks. Mats can be decorated as described below, used as surfaces for continuation of deep artwork, or can combine three dimensional aspects, although the latter two are highly unusual.
The mat is quite adaptable in a visual sense. Because they're usually pretty thin (American-made mats are usually 1/16 inch thick, for example), they can be cut to "stack" inside the screen, allow for double, triple or four-fold webbing, or even allow fillets between mats. Mats are available in different colors and shades and, more rarely, in pre-printed patterns or designs. Mats can easily be found or changed to include further decorative features, such as cover (most often linen or silk, though mats with leather cover or various types of coverings are also available from some companies) or decorative or other coatings. (such as metallic coatings, or textured and patterned coatings that may include rice paper).
Because the mattress is thin, but not thin, it can also be carved (traditionally by hand, although the computer's cutting system has also been developed), to display designs, such as simple letters or drawings; because the engraving consists mainly of cutting a small portion of the decorative layer over the mat, this means that the engraving design will appear as the core color of the mat. (There are examples of sandpaper used to sand into a mat and reveal a core, or an incision made into it with the same result.) Most mats are available with a white core, black core, or standard core (cream-colored), but some mats also available in bright green, red, yellow or blue.
While most mats are generally rectangular, with rectangular openings, in addition to fairly common ovals, oval-apertured mats designed to go with an oval frame, there is also a very unusual example of mats in other forms.
Mats, with very few exceptions, are made from paper-based materials. They tend to take a good surface addition, including ink and paint (various other media, including circles, have been used); cloth-coated mats can also have objects such as pins, flags or patches of fabric embedded or sewn to them, a technique often used in shadowboxing to avoid having items taped to backing. It is also possible to attach a small metal plate to the surface of the mat. Such plates are usually made of brass, and can also be attached to the frame of the photo itself if the frame is made of wood.
The most common form of decoration on fabric-covered bases is the French or line line, and the panel French panel or I. The line French or the line is a line drawn on a mat, usually with ink or paint and usually drawn to form a complete rectangle or square around the opening on the mat. It is used as an additional decoration to help draw the eye toward the center of the screen, and can be done with pencil or color ink or paint, including metallic ink. The French panel or panel is similar to the French line, with a thicker exception, formed from decorative materials ranging from gold leaf to ink or paint design. Usually a painted French panel will be done in watercolor, which is sometimes also referred to as a watercolor panel .
Similar to the French Line, is the V-Groove. A V-Groove is a thin piece into the mat around the opening edge, revealing the core. It is used for almost the same purpose as the French Line.
The most commonly used webbing has the same margin all the way. In artwork with a lower visual center than the actual center. The bottom, or off-set weight is often used in webbing. The bottom margin is made larger than the sides and upper margins. When viewing the image, the eye tends to center higher than the physical center of the image. By creating a larger bottom margin and off-setting mat you draw your eye to the physical center of the image. The Top Center is part of the bottom weights where the top and side margins are the same, which creates a pleasing visual effect. This is especially true on mats where the boundaries are not the same, like 11x14 with an opening of 8x10.
Protection
In the archive or conservation picture frame, the mat has several important functions. One of the most important functions is to separate glass from art or framed documents; This is especially important because any condensation that develops inside the glass can be transferred to pieces if they are not separated, resulting in water damage, mold or mildew. The photo should also be separated from the glass because the surface of the photo is very easily damaged, and may even be separated from the original paper and attached to the glass if wet; for this reason, each photo-framed value must be framed in such a way that the glass does not directly contact the photo. In addition, some types of art, such as pastels or chalk drawings, can fade easily and should be separated from the glass for that reason.
Another major function of mats in the framing archive (where mats used are made of acid-free paper and lignin) come into play during the installation process. In archiving archives, paper items are usually not glued back, as it prevents anyone in the future from releasing them safely and easily to replace damaged skeletons, mats or mats, and can make the recovery of damaged documents or art. cut more difficult. Normally, such items are not held in place against support with mylar "photo corners" (small triangle pockets where paper corners are laid). The weight of the added mat (although slightly) can help hold the pieces while also helping to hide the back and corners of the photo. In archiving frames, mats are not attached to sections or backs, but are "hinged" to the backs with ribbons, although if more than one mat is used, the mats are usually taped to one another.

Acid vs. "acid free"
There are two main types of mat materials: acid, and "acid free" (neutral pH). Older mats (wood-based paper) are usually acidic, because acid-free paper is not widely available or marketed until recent years. While most newer mats are acid-free, there are some papers that contain acid and one should ask the image-makers about the acid content of the mats if the desired life of the framed pieces is more than 75-100 years.
This difference is important for the long-term protection of the cut because the acid mat can cause so-called mat burn , a brown mark that crawls from the outside to the displayed part itself. While the mat burn can sometimes be reversed through cleaning the pieces, cleaning may not be feasible if the piece is executed in ink or water-soluble paint, such as watercolors. Thus, it is important to know whether the mat used is acid free if the piece has to be preserved for a long time.
To determine the pH of an older mat with a white core, see whether the core (seen where the mat has been cut) has turned brownish or yellowing; if so, it is acidic. If the core does not change color, one can determine the pH by using a pH tester.
There are several categories of board mats and they are all separated by the level of protection offered by artwork or framed artifacts. While some say that acid framing materials should be avoided for all but the most transient frames, it is not safe to say that all "acid-free" mats are recommended for long-term preservation use. The hierarchy of board quality is as follows:
- Museum Board - Highest quality materials available. It is made of 100% cotton fiber, is Archival and will protect and preserve the contents of the frame. Although this is the most expensive material available, the difference in material costs actually relative to the cost of framing is minimal.
- Museum Mat or Rag Mat - Still a good quality choice for conservation, this is made from cotton linter and medium cellulose. Cellulose is a cheaper raw material but offers considerable conservation properties for most jobs.
- Conservation Archive Board or Archive - Built from 100% high alpha cellulose (wood pulp) and treated inert to 300 years. This is the highest quality paper mats available.
- Acid Free or Acid Free Color - This material is usually coated with wood-based coatings on one or both sides that have been treated to prevent "short-term" acid burning - above the core recycled fibers. Eventually the acid in the core will leak onto the surface that can damage the artwork.
Care must be taken in choosing the desired framing type. The desired artwork for long-lasting survival (over 75 years) can be undermined by inappropriate mat boards that are used deliberately for a lower cost. However, non-archival quality boards may be suitable for photo printing, laser printing, etc. Which is not meant to last long term. In addition, prints made with the traditional chemical processing of photographic film (ie darkroom development), compared to computer printing, are slightly acidic and therefore much less likely to be damaged by non-arch mats.
In addition, the correct "conservation" framing includes all the components, not just the mat boards used directly behind the glass. To date, there are no "really" archive-quality board foam boards available, although a number of foamcore brands exist with surface buffers and the Nielsen Bainbridge company is now producing one that is claimed to block air pollutant intrusions and to avoid problems. outgassing that non-archival foamboards can become prey; for this reason, and since many smaller frames' depth is shallow, it's not uncommon to see the mat boards used as backing for photo frames as well, although foam boards and mounting tend to be stiff. It is also important, if long-term preservation is of concern, to ensure the shaper uses good conservation framing techniques.
Technology
Mats can now be cut using a computerized Mat Cutter. Cutting mats are available in various sizes and allow mats to be cut with accuracy and precision. This makes it ideal for complex mats, multi-window mats, oval or shaped mats or even cutting mats.
