Test methods and criteria for the estimation of life expectancy for the items listed below are proposed based on experimental data and market surveys:1) Dark stability, 2) Lightfastness, 3) Ozone gas fastness, including reciprocity failure problem, 4) Humidity fastness, and 5) Short-term color shift.Image stability of the following digital printing materials was evaluated based on the proposed methods; a) Ink-jet, b) Xerography, c) Dye-sublimation, d) Pictorography, and e) AgX color photographic paper.
