The listing, Nell Gwynn's House (Dufex Foil Print #155266) has ended.DUFEX is a highly distinctive foil printing and embossing technique developed by F.J. Warren LTD, England. DUFEX adds the extra dimensions of light, movement and depth to these foil prints. The DUFEX effect begins by printing images onto aluminum foil lined paper, using UV formulated transparent inks, which allow the reflective shine to be retained. Then, using special engraving techniques, a range of stunning light reflective textures are added to the foil, thereby uniquely enhancing each design. This creates a three dimensional "illusion of movement" image. All foils measure 6" X 8" (6 1/4 X 8 1/4 including border).
