[1]Prints made with HP 85 Ink Cartridges and HP Premium Plus Papers may be displayed indoors under glass for 82 years before noticeable fading and staining will occur, according to Wilhelm Imaging Research (see http://www.wilhelm-research.com for details). Display Permanence Ratings are based on accelerated light stability tests conducted at 35 klux with glass-filtered cool white fluorescent illumination with the sample plane air temperature maintained at 24° C and 60% relative humidity. Data were extrapolated to display conditions of 450 lux for 12 hours per day using the Wilhelm Imaging Research, Inc. "Visually-Weighted Endpoint Criteria Set v3.0" and represent the years of display for easily noticeable fading, changes in color balance, and/or staining to occur.
