The media and mounting choices explained:
W/C - Paper, in most cases a watercolor paper with a slightly textured surface prepared for inkjet printing. We are using more often now, a smooth surfaced higher gamut paper as well. This more expensive paper has slightly better saturation and deeper blacks.
MDF - Medium Density Fiberboard at 1/2” thick, set 1 1/2” off the wall on a 1x frame— painted and sealed front and back, and edges.
NO WRAP - The canvas or paper is cut very cleanly at the front edge of the backing and burnished to that edge. The exposed MDF edges are sanded smooth and painted to fit the colors of the piece or interior. This is the most time consuming treatment—giving a very contemporary result. A 1/2” MDF backing with a 1 1/2” hidden frame behind is used for this treatment.
WRAP - Only canvas, in this case, is wrapped around the edge and stapled and glued to the back of the MDF. The canvas is printed oversize with a reflection of the image printed to wrap around the edge so none of the original image is lost in the wrap. Corners are folded, usually top and bottom. A 1/2” MDF backing with a 1 1/2” hidden frame behind is used for this treatment.
WRAP + FRAME - See above for a definition of wrap. In addition a thin natural wood frame is set off by 1/2” of shadow from the canvas edge. This gives a slightly more formal or classical look.
