Before ordering new MIS FS Neutral bottles for my Epson 1160 CIS 
system, do you know if the problem with the new Eboni black is solved?

Since the introduction of the new black, I have read a lot of 
complies about cloging (I have never suffered any serious clogs with 
the MIS FS Neutral old version): have they modified their formula 
since?

Is there any visual improvement between the older version of MIS FS 
quads and the new ones with Eboni black?

thank you for your advice.
