Since then I have submitted two more of the same inks, one on a completely different brand of paper, as well as the HP monochrome samples, Piezo K7 Carbon Sepia etc. But those will take a while to determine. The Selenium K7 set is also in test by someone else.

Yup,

They are in test and will appear in the AaI&A database at the 10 megalux hour mark in another few weeks. Stay tuned! 

Of the many challenges to this type of work, getting good representative fully randomized samples for testing takes considerable time and effort. But that was part of the method to my madness when I created the  AaI&A membership and sample submission concept...i.e. that we would be able to get true random replicates from end-users and that the replicates, at least for popular and important processes, would get tested as well. Your recent sample submissions show the concept is working!

I know Jon has concerns that this first sample of K6 Neutral on HN photo Rag now in test may have some production related batch issues and that newer K6 neutral and/or Selenium ink batches may provide a potentially better outcome.  No problem, we keep testing, and we keep working towards a good average megalux hour rating for the different tints (neutral, selenium, special editions, etc.) because these are all beautiful, historically significant examples in this era of digital print making.  I want the museums and archives community to have very good data on how to take care of them indefinitely.
