Why Don t Jon Cone s Quadtone Inks Absorb into Pictorico OHP Film?
I went the route of getting an Epson 1160 with the Piezography system from Jon Cone, hoping for great quality Pictorico OHP negs. Unfortunately, the ink doesn’t adhere to this base well. How do you protect the negative on this material? Some have used lacquer spray, others have used thin Mylar sheets. What have you used with success on this? Both. The .002″ Mylar (available at art supply stores) works well but can abrade the pigment image if the negative/Mylar sandwich isn’t handled carefully. I know because I’ve transported some such negs around the country and have seen them damaged from the handling. For in-studio use, where we store and handle negatives much more gently, it shouldn’t be a problem to attach the Mylar to the negative with tape. I now spray my Cone quadtone negatives. My best resultsmost even spray, fastest drying time and lowest stink factorhave been with the Clear Acrylic Matte Coating from Crafts, Etc. I found this spray at our local Hobby Lobby.
