Jon Cone invented quad-black inkjet printing back in the early 1990s. Today, Piezography® Pro uses 11 different monochromatic inks, nine of which are gradated to produce tens of thousands more gray levels than can Canon, Epson or HP with their printers. We also formulate the world’s darkest matte and photo black inks. Whether you choose fine art matte or fine art glossy/baryta, our Piezography Pro prints will make your work come alive with greater dMax, superior shadow and highlight detail, higher acuity, and a significantly smoother tonal response. The surface of a Piezography print is absolutely unique in the print world.
