Digital BW, The Print

Are these two inksets compatible in terms of their native chemistry.  If so, then the dilutions could be manipulated by some variable amount to utilize in different printers.  Specifically, I have a 1280 using the MIS CFS system to support the UT2 Eboni set.  I read on one of Paul Roark's web pages the inks were, I believe he said, 'similar'.

Has anyone had any experience using the UT2 Eboni inkset in a K3 printer like the 2200?  That's my target printer.  I'd like to be able to either use both printers on the same inkset to hold my costs down or get rid of the 1280 and use just the 2200.

You thoughts and help are, as always, greatly appreciated.

Thanks, Mike
