UltraChrome HD pigment inks are also expected to have WIR Album and Dark Storage Permanence Ratings well in excess of 200 years; the prints exhibit high resistance to atmospheric ozone; have very good water-resistance properties; and, the pigment images are extremely resistant to damage caused by storage or display in high-humidity environments. In addition, preliminary data from ongoing tests indicate that, depending on the specific paper, WIR Display Permanence Ratings for black and white prints made with UltraChrome HD inks using Epson’s “Advanced Black and White Print Mode” will likely exceed 400 years.
