Guide to Printing, Mounting, and Finishing your Work

The below is meant as a guide to Duggal’s standard production practices and terminology for mounting of digital c-prints, Giclee, or inkjet prints.

Brief Explanation: Mounting


Surface Mounting– is the process in which the printed image is adhered on top of the material with the adhesive being on the back of the print. This is the most common mounting practice.

Face Mounting– also referred to as 2nd surface mounting, is when a clear adhesive is used and applied on top of the print and then the print is mounted behind a clear substrate such as acrylic or polycarbonate (lexan).


Foamcore– (IMAGE) This is a thin lightweight mount with an inner layer of foamed plastic. Used for lightweight mounting and temporary displays. Available in ¼” and ½” thickness with a black or white finish.  Sheet sizes are 48×96 and 60×96 at .25 inch thickness, and 48×96 for .5 inch. Can be cut by hand and is dramatically quicker and easier to mount verse other substrates so this is our least expensive option. This material dents easily.

Gator Board– (IMAGE) More durable than foamcore, this polystyrene foam board is bonded on both sides for uniformity and greater rigidity. Available in a black or white finish. Standard thickness is ¼” and ½” but thicker boards are available up to 2 inches. Great for temporary displays or exhibition pieces.  Boards come 48×96 and 60×120.

Sintra (IMAGE) is a lightweight PVC based material, suitable for indoor and outdoor projects. Standard colors (Black & White) are in stock while other custom colors are available upon special request. Sintra has cleaner and better appearing edges / sides than Gatorboard and comes in larger sizes. This material comes in either black or white. It is a semi rigid material made from compressed PVC.  Very durable. At medium to larger sizes and lower thicknesses it is flexible. Extreme flexing may wrinkle or crease mounted prints.   Boards are available in 48×96, 48×120, 60×120 and 79×120.

Aluminum (IMAGE) Standard stock includes.063 mm and .08 mm. Thicker gauges can be ordered.   Anodized aluminum comes 48×96 and 60×120, and a non anodized aluminum is available 72×120.

Dibond– (IMAGE) Dibond is comprised of two different materials. A layer of black sintra is sandwiched between two thin layers of aluminum. This provides for an extremely flat and rigid material that is durable for even outdoor use.  It is more dent and bend resistant than aluminum.  Board sizes of 48×96 and 48×120 are available in white and 48×96 is available in a brushed aluminum metallic finish.

Acrylic  (IMAGE)  comes in a variety of colors and finishes. The most common are clear, milk, white, black, and matte black. If you are interested in any unique color options please inquire.  Sizes typically available up to 72×120 with .125 and .25 thickness the most common thickness used for mounting though thicker sheets are available but get increasingly heavy.

P-99– This is a clear non –glare acrylic that has a matte finish. The matte finish removes glare and reflection that are common to other acrylic and glass.  It is only useful to use P-99 for face mounting.

Backing and Hanging Options


Wood Brace– (IMAGE) Wood braces can be used on any material but foamcore is generally excluded from this. The wood brace serves several functions: extra support for large/flexible pieces, creates depth from the wall, extra surface are for handling heavy loads and it is the means by which the print is hung on the wall utilizing two matching cleats.  A 3/4 inch wood brace with cleat is used to float images off the wall. For prints larger than 40” x 50”, we suggest using an aluminum brace if the piece is to be archival as wood can warp over time particularly in an environment with significant moisture.

Aluminum Brace– (IMAGE) Aluminum Braces serve the same functions as wood braces do however they are dramatically more rigid and archival. They are chosen either for aesthetic purposes or for supporting the largest and heaviest of prints. 1 inch aluminum tube brace is used for archival mounting. Ideal for museum and exhibition mounting. Aluminum braces are significantly more expensive and time consuming to produce so they should not be used for temporary displays.

Gatorboard Braces– To be used only for gatorboard mounts a brace fabricated out of .5 gator is an inexpensive option suitable for temporary displays.  The Gator Unit listed in our price list incorporates a gator brace.


Velcro– Using velcro is a simple and cost effective method for hanging prints. This is primarily used for images that will have a short life span and/or will be changed out frequently. Velcro has a low sheer strength. In consideration of this, it usually only used to hang foamcore, gator board, or sintra. Where the velcro will be adhered to should be taken into account. For delicate painted surfaces that cannot be damaged low tack self adhesive vinyl should be applied to the wall where the velcro will be installed to prevent any damage upon removal to the wall surface.

Easels– are made of compressed cardboard (there are other kinds) and used to stand prints upright on the floor or on a desk. Used only for lightweight materials such as illustration board, foamcore and gator board prints under 30” high.   For larger pieces or heavier materials we custom fabricate easels out of other materials including gatorboard and acrylic.

Z-clips– are metal channels with one piece adhered to the back of the mounted piece and an interlocking piece is installed on the wall so that the print can hook right on to the wall.  This method is stronger than a standard cleat and it has a thinner profile so the mounted pieces sit closer against the wall.
