Digital BW, The Print

My two cents worth- 

I've already received a bottle of the Eboni K ( good timing and 
proximity I guess) and I did swab tests of that, the Museum K, Epson 
Arc-K and Gen-4 K. Now, I know Paul's densitometer sez that the 
Museum and Eboni are identical. However, when I laid a patch of the 
Museum K across side-by-side patches of Eboni and Museum, the patch 
blened perfectly with it's own kind, but did not blend with the 
Eboni-the ebony was just a tad lighter. A minor difference mind you, 
but there. For what it's worth.

 While I'm offering tidbits of dubious value: here's one for 7k 
printer owners faced with changing inks: If you take the dampers of 
the head, apply a syringe w/ bottom fill adapter, and suck out 15ml 
of ink, you be into the new ink. Another 2-3ml to positively clear 
the mixed ink out of the dampers, 2-4 regular cleaning cycles to get 
the air out of the head, and you're done, without taking 15% of the 
lifespan of your waste ink tank or wasting a lot of ink.
