That is consistent with my tests (with a blended B&W inkset, not 100% carbon).  However, the fade testing is not going to show what the long term staying power is  of the coatings with respect to cracking and separation.  We have no good accelerated age testing information.  My belief is that Wilhelm's tests are at a constant temperature and humidity, thus not subjecting the paper to the termperature and humidity swings that probably present  the most  serious risk.  

So with respect to how the paper itself will hold up  we're stuck more with the historical experience, and we just do  not have that data with respect to the coated inkjet papers.  Arches, on the other hand, has stood the test of  time.  So, I read the original question(perhaps  incorrectily) as including paper longevity as well as ink longevity, and I suspect the carbon will  last long enough that the substrate itself may be  a limiting factor.

Of course, don't  get me wrong,  I use mostly coated paper.  Moreover, I think the new coated Epson Hot Press Natural looks great with the carbon inks (and I see it's now also available in rolls).  I'm hopeful the coated papers will last, but I think there  is more uncertainty than with an uncoated paper like Arches.
