Framing can help prevent this. Foam Core board is absorbent and will warp. Gator is much less prone to warping. Due to the possibility of damage during finishing, we suggest that only prints be mounted and laminated. Stockton Blue does not accept liability for such damage.
Flat pieces work best.
Pieces with overlays or layers may cause problems, especially if laminated. Some materials, especially thermal prints, may experience a color shift when laminated. Special cutting of most any shape. Wall hangers applied. Special hinging applied, black and white available.
