Our Ready to Hang Art Boards are NOT the stretched canvas prints, but surpassed the latter. The former is designed for upgrading and replacing the latter. The former is rare on the market so far. You are encouraged to compare them. We use long lasting inks to print images on advertising industry PVC and cover with special wateproof protecting film, then mount them on 1" thick special structure HDF **(High-Density Fiberboard ) or 0.4" thick MDF*(Mdium-Density Fiberboard). THIS IS THE LATEST WALL ART PRINT PANELS PRODUCING TECHNOLOGY. These unique high quality Ready to Hang Digital Art Print Panels are nothing short of spectacular, looking much more expensive than they are. They will greatly brighten your home or office. *MDF (Medium-density fiberboard) is an engineered wood product formed by breaking down hardwood or softwood residuals into wood fibers, combining it with wax and a resin binder, and forming panels by applying high temperature and pressure. MDF is denser than plywood. **HDF (High-density fiberboard) is similar to medium-density fiberboard, but is denser and much stronger and harder because it is made out of exploded wood fibers that have been highly compressed.
