I used to be a perfectionist and use separate ones. No more. With regard to rinsing, the best rinse is probably the clear base you're using. Not tap water. If you start with the lightest c6b dilution and work your way up to the MK, you have that base with a little carbon in it. That's even better than the pure base in terms of slightly over-diluting the next ink. So, what I recommend for the carbon partition is to just pump the syringe with the needle down and blow out most of the lighter ink. Then you're ready for the next one.
If you use a toner like I do, it also uses the c6b base. Both before and after that ink, I rinse with tap water and then the clear base.
