Here's the real hardcore test for the archival properties of Piezography and Epson 1290 (Epson ink) prints versus Fuji Pictrography 4000 prints. At a seaside condo in Huahin, two hours south of Bangkok, I had until late last year fifteen 12x18 inch Fuji Pictrography 4000 prints hanging on the walls, 12 B&W and 3 color, framed under glass. While the prints do not get any direct sunlight, and the shades are down all the time except on the average of three days per month, the environment is harsh in that the temperture is usually above 90°F and often above 100°; and the weather generally humid some nine months per year. I also have a large Lambda print on Kodal Panalure paper at the same condo. Fuji Pictrography 4000 prints didn't do well in this environment: after two months all the prints, color and B&W, had a noticeable green tinge; and after sixth months all the Pictrography prints had a heavy green cast and some fading. In contrast, the Lambda Kodak Panalure print, which is on a wall that does get some direct sunlight, did not change at all. I suppose that the problem for the Pictrography prints may be the heat and humidity, as the Pictrography process uses a silver halide process to develop the "donor" paper that has been exposed by laser and then transfers to the print paper by dye transfer; and there may be some chemicals left on the prints. Last December I replaced the 12 B&W Pictrography prints with Piezography prints made with Cone inks on Epson Archival Matte paper and the three color prints with Epson 1290 prints with Epson dye inks on Epson Heavyweight Matte. Now, after six months, I cannot discern any change in the either the Piezography B&W or the Epson 1290 color prints. Quite a difference from the Pictrography prints! From what I have read, I expected the Piezography prints to be a little warmer after six months; but I don't see any change. However, as these prints are under glass, perhaps they look a little cooler; and the warmer is not visibloe when compared to new prints not under glass. --Mitch/Bangkok - Turn off HTML mail features.
