It also says the significant change is the move of the optical brighteners from the inkjet receptor layer into the RC base. This feature means the paper will be more resistant to fading and yellowing as optical brighteners can breakdown over time due to exposure to sunlight and other sources of UV radiation. This change significantly improves the archival characteristics of the paper.
In order to reinforce the importance of the changes, DES contracted the Image Permanence Institute (IPI) at the Rochester Institute of Technology to run comparative light stability tests on digital prints made on the new Chromajet Centurion 285.
The prints used for testing were produced with the latest Epson ink sets - UltraChrome K3 and UltraChrome K3 Vivid Magenta, and the latest Canon ink sets - Lucia 12-ink pigment system. These prints were then exposed to high-intensity cool-white fluorescent light in order to simulate fluorescent room illumination without glazing for approximately 50 years.
After rigorous testing, RIT concluded that "all samples performed very well under the test conditions, showing no significant changes during the extent of the incubation." The results indicate that the predicted display life time for all these materials are truly impressive, with none of the samples showing any signs of fading or yellowing during light exposure.
Ian Clare, managing director at DES says, "The Chromajet Centurion 285gsm Gloss and Silky digital photo papers are specifically designed for high quality, professional output. These are the most advanced papers available on today's market and the results we've achieved under independent testing have been outstanding."
The papers are available exclusively from DES, in rolls and cut sheets in a wide range of sizes, and are aimed at the professional photography market. The papers are produced by Mitsubishi Paper Mills.
