The measurements were all made between 12-36 hours after printing—i measure immediately after and then again after they are dry to see the effects of dry down—really just for my own curiosity. The tests were not made with Cone Selenium Shade 1, which is a photo-black/gloss compatible ink. I used Piezography Neutral Matte Black for shade 1 and Selenium Shade 2 (also gloss compatible, but used in both gloss/matte inksets). The Peizography Matte Black is well within the expiry date, but the selenium inks I have are 3 years old and I don't know how that effects the ink limit measurements.
Also, someone mentioned that the MIS inks are now called "Ebony" but rather Eboni, which my browser's spell check doesn't seem to like. . .
