I see.  Paul has the additional requirement that he has to match with
what the Epson drivers do -- i.e. there's no control of  individual ink limits.

I'm not too sure what would be the best dilution to use.  I don't think
it's too critical, you'll just get different ink limits.  It's interesting to
note that Paul's formula has an equal amount of full strength M and Y.
