A

Allowance- This allows extra space in the widths and lengths of the frame to ensure all that go into the frame (photo, matting, mounting boards, backing and glazing) have an accurate fit. It provides space for expansion of the paper-based materials to expand and contract to changes in temperature and humidity.

 

Antiquing- This enables one to mimic the appearance an antique picture frame. Antiquing is accomplished with the use of a buffing chemical, scratching and painting.

 

Archival framing- This framing philosophy is focused on protecting and preserving the photo. With archival framing, only acid-free materials come in contact with the photo. The mounting techniques employed are reversible which means the photo can be removed from the frame without damage.

 

Artwork Size- the measured size of the actual image, not including borders or paper size.

 

ATG Tape- Adhesive Transfer tape also called snot tape, a double-sided adhesive used in picture framing to secure mat boards and dust covers. This tape creates a strong, durable bond with plastic, metal, vinyl, cloth, and other materials, making it ideal for framing and other home projects. Acid-free versions of ATG tape ensures your art, photos and prints won’t be damaged when mounting mat board or scrapbooking.

 

B

Back Paper -aka a dust cover, is liner paper adhered to the back of a frame. The back paper keeps dust and insects out of the frame package. It also helps reduce fluctuations in humidity, limits the infiltration of environmental gases, and gives your framed artwork a professional look.

 

Backing. Also called the mounting board, is where the photo is attached before it is placed inside the frame. The backing keeps the photo in place and to prevent the photo from creasing and warping.

 

Beveled Edge- when the inside edge of the mat board window is cut to a 45 degree angle.






 

C

Cardstock- specialized craft paper that is thicker and stiffer. This can serve as backing of the photograph or artwork to prevent it from buckling.

 

Canvas Floater Frame- a type of frame used to display a gallery wrap canvas. This frame allows the entire front surface of the canvas to be visible. Any color applied to the canvas wrapping the sides of the stretcher bars will be somewhat visible in the ‘float’ space.

 

Conservation Framing- a type of framing- including materials such as mat board, mount board, glass and acrylic- that keeps the artwork as unaltered as possible while using materials which minimize the artwork’s deterioration by environmental factors.

 

Conservator- a professional who specializes in the restoration and conservation of artifacts such as photographs, artwork, and documents. Conservators examine artifacts, determine their condition, suggest methods for treating them and recommend preventive conservation techniques to their owners.

D

Dust Cover- a liner paper adhered to the back of a frame. Dust cover keeps dust and insects out of the frame package. It helps reduce fluctuations in humidity, limits the infiltration of environmental gases, and gives your framed artwork a professional look.



 

E

Enamel- For wood frames, an extra layer of enamel is added to the wood for aesthetics and protective purposes. Enamel can be semi-transparent or opaque.


 

Euro Hanger- a device for hanging pictures. Two hangers are needed to hang a picture - one on each side. The hangers are normally positioned 1/3 of the way down the from the top of the frame. A screw driver is used to tighten the set screw. The hanging wire is threaded through the eyelet.



 

F

Finger-jointing reduces wood waste by utilizing shorts to create a dimensionally stable and environmentally friendly product.

 

Flat Head Screwdriver- a screwdriver that is designed to fit into slotted screws.

 

Float Mount- a mounting technique where the edges of the artwork are left uncovered by a mat board. With this application the artwork appears to be floating within the frame or mat board window. Artwork can also be float-mounted on a piece of black or white foam core without a mat.

 

Foam Core- the board on which artwork is mounted upon inside of a picture frame. Foamcore mount board is a light, but stiff material that is commonly available in white and black. Acid-free varieties are available for conservation framing.
