By the way, in one centrifuge test I stuck in a sample of 7800 LLK. As you'd expect, it's quite stable in terms of the Lab L. What surprised me is that the Lab A changed. The top of the test tube changed from Lab A = 0.05 to Lab A = 0.2. This is way more than I've ever seen any carbon ink change. The K3 LLK is too green to me, and I've suspected that Epson put in a bit of cyan. This centrifuge test is consistent with it being a blended ink. Paul www.PaulRoark.com
