Not enough light fade data yet to make any generalizations about these two papers yet. Closest comparison I have at the moment is the Rag Photographique printed with Epson HDR inks at 50 megalux hours (sample # AaI_20090408_SN001) compared to HPR with Epson K3 inks at that same exposure dose (sample # AaI_20080113_SN003). The latter sample has gone over 100 megalux hours and has conservation display ratings completed now.  Need to continue the Rag Photographigue sample further in test to get to the conservation display ratings (still passing lower and upper limit boundaries) and see how things fare at the 100+ megalux hour mark. So far the two papers look to be tracking similarly with Epson inks and no major differences have appeared yet between K3 and HDR inks on various papers though some subtle differences are beginning with certain colors.  That said, HPR turns in exceptionally good performance with Canon Lucia pigment inks, much better than the Epson ink, and outperforming other papers like Museo with the Lucia inks. The moral of the story is that one really needs to test each printer/ink/paper combination as a total entity. Extrapolating ink or paper performance to other systems is risky. 

John, you kindly submitted an HPR sample with the Z3100 Vivera inks, but it just got started in test. Yet once the test goes further we will then have some good HPR data on Epson, Canon, and HP pigment sets for this widely used paper. No reason the Canson papers won't get there, too, as more AaI&A members begin to use them.

Hence, sooner or later I expect to have both papers well represented in the AaI&A light fade database printed with the major OEM ink sets in both color and B&W output. Getting a lot of B&W samples coming in on these papers as well including some popular monochrome ink sets which should be of special interest to this forum.  AaI&A members are helping me get there. It takes time. Patience is a virtue!

regards,
Mark
