Keeping the prints in the right environment will maximize their life. Direct sunlight will cause the colors to fade prematurely. Pollutants such as smoke will also negatively impact the lifespan of the media. Excess humidity may cause molding. Extreme low humidity will cause the wood stretcher frame to shrink which may cause the stretch to be less tight and result in sagging. This effect is temporary and will go away once it returns to a normal humidity range. The lighting conditions also affect how the prints will be viewed. Our monitors and printers are calibrated to ambient light conditions of D50 (5000K daylight). Viewing under different light conditions may affect how the colors are perceived by your eyes. The archival eco-solvent inks are more sensitive to display color temperatures. If your prints will be displayed under warmer lighting conditions (yellow) we recommend you select the option for the archival pigment inks (with or without varnish) rather than the archival eco-solvent inks.
