A substrate is a rigid, board-like material onto which a print is adhesively mounted for display. We mount prints on two substrates: |
||
|
1. |
Gator board (½"): an extruded polystyrene foam board bonded between two thin layers of melamine-wood fiber veneer. Much stronger than foam board but about the same weight, at 1/3 lb./sq. ft. a 44"x84"x½" gator board weighs 8½ lbs. Its lightness and rigidity make it ideal for home wall-mounting, and metal hangers easily pierce halfway through its back for that purpose. With a harder outer surface than other foam core boards it resists warping. All seven prints in the mounted print gallery are mounted on ½" gator board. |

2. |
Dibond (3mm, ⅛"): a sandwich of two 0.012" aluminum sheets around a low-density polyethylene core. Smoother than gator board, dibond is lighter and more rigid than solid aluminum sheet. At 0.79 lb./sq. ft., a 44"x84"x⅛" dibond sheet weighs 20¼ lbs. Although not pierceable for easy hanging and over twice as heavy as gator, its appearance is superior, thinner, and more modern. |
