Second surface printing is the process of printing on the backside of a clear material. The ink is printed on the backside of the material allowing it to be protected from fading and wearing over time.
The Heinz History Center in Pittsburgh, Pennsylvania contacted Print On Carpet to collaborate on creating custom vinyl flooring. The printed flooring was to cover a 16 ft. x 32 ft. space and was produced in four panels 8 ft. x 16 ft. This piece was printed using a 4 color process plus white with a water-based liquid lamination over the ink on the printed side. Due to all the foot traffic expected in the space the flooring was printed second surface, meaning that the ink was laid on the underside of the floor. The floor would be flipped and the image would be seen through the clear flooring without any foot traffic affecting the ink. It was installed using a water-based adhesive.
