Gamut of newspaper prints in function of the environment

Light and gas fastness are two very important aspects of print quality. The aim of this proceeding is to determine light and pollutant impact on the gamut of prints through exposure of samples to artificial, glass filtered and direct sun-light, as well as common gas pollutants. Exposed samples were analysed by densitometric and spectrophotometric methods and statistically processed in order to determine the correlation between time and type of exposure and gamut changes. The results show a significant impact of combined direct sunlight and pollutants on prints. Beside the scientific aspect, these results could be used as guidelines for manufacturers and printers to improve the quality, while still maintaining low production costs.
