MDO signs or Medium Density Overlay is a wood composite sign with a smooth painted overlay on one or both sides. We print on the smooth painted side with UV ink and in some instances we will laminate the side of the print with a gloss or matte clear coat to prevent fading and discoloration. These signs are typically 96" x 48" horizontal or vertical, single or double sided. Using those numbers you can enlarge signs to 96" x 96", 96" x 144", or any combination of 96" x 48" pane
