Yes, I found it on the internet.  I must say, however, the sample Dow 
sent to me will probably last me for many years.

I'll continue to pursue the issue.

By the way, at least for low load inks a 20% glycerin viscosity mix 
appears to keep Eboni in solution and runs in Canon dye printers.

I read that the 1900 has little ball bearings in the reservoir to 
keep the inks mixed.  That may mean they've gone to a lower viscosity 
ink to get it through those tiny nozzles at higher speeds.
