All prints are produced with an Epson 9600 inkjet printer with Ultrachrome Inkset. They have a rich, matte surface and resemble photo-lithographs more than photographs. All images are printed on Hanemuhle German Etching paper 310 gram weight. Ultrachrome Inkset archival inks are rated for approximately 100 years under optimum conditions behind glass in stable environments. These specifications are available from Epson HERE. The prints are susceptible to water damage if not protected and must not be exposed to direct sunlight.
