The long-term stability of inkjet photographic prints is known to be sensitive to a variety of factors. The chemical composition of the inks (pigments vs dyes) and media (porous vs swellable), as well as the ambient environmental conditions (light, heat, humidity, air quality) under which the prints are stored and/or displayed, are known to affect image stability. In order to correlate the results of accelerated testing in the laboratory with what actually happens to a photographic print under longer-term real-world conditions, it is necessary to better understand the typical ambient environment in which the prints are being displayed and/or stored. To this end, we have measured the long-term light levels, spectral energy distributions, temperatures, and humidities in 32 homes in 4 cities around the world. In this presentation, we will attempt to quantify the typical home display environment and compare similarities and differences among the homes and cities included in this study.
