"The binders in the Eboni
are of a lesser quantity and it must play a role."

I'm curious how it is known that the Eboni inks have "binders of a lesser quality",  what the two binders are and in fact how they would play a role.  Are you saying that this is done in order to make the ink at a lower price, and one is chemically good and the other responsible for your clogs?  I would like to know more.

  I had an InkjetFly Small Foot CIS loaded with 3 Eboni Channels and 5
  clear base channels for months and never had any issue. That is also
  with leaving the printer off and not printing for 2-3 weeks.

  Then I decided to flush the CIS, clean it completely and fill it with
  MIS color pigments for the R1800.

  After 2 weeks of non use, all nozzle check patterns where missing many
  lines.

  Removed the CIS and loaded MIS carts - 3 Eboni and 5 clear base. It
  took many cleaning cycles and an overnight stay of the printhead on
  the parking pad filled with window cleaner to finally remove the clogs.

  I suspect the type of ink might play a part. The binders in the Eboni
  are of a lesser quantity and it must play a role.

  I'm done with color on the R1800 unless I buy genuine carts.

  I'll flush the CIS again and bring it back to 3 Eboni abd 5 clear base
  channels! :-)

  Just my experience.
