Have you tried taking the prints under differing > lighting to compare metamerism? Paul, Just tried under a couple of different fluorescent lights and still couldn't tell the difference. I thought I knew which one was changing slightly, but that turned out to be the K7 print. Too close to call. The difference in fade resistance is a significant point that one can't see in this visual comparison. Looking at prints further under a loupe, the K7 print is definitely smoother in the transitions. However, while I can almost convince myself that I can see the difference in smoothness of an abrupt light/dark transition from 8 inches away, probably I would only get about 50% right if the test was done "blindly". Thanks. --John
