Hi Paul. When you were developing your UT formulas you listed an experimental base for the inks. I believe it was a mix of H2O/glycerol at 4:3. Would I be mistaken in assuming that base mix could be used as a universal flush solution for switching between the old pig types(color/VM's etc) and the new UT/UC etc types and Eboni? Thanks. Duane

Duane, I think that formula might work. But, I've also learned that some of the flushing fluid is more watered down to lower the viscosity. This allows it to get into and through, for example damper screens, that the higher viscosity fluids will not get through as easily. So, if you want a cheap flushing fluid, you might want to dilute my "UC base" a bit more. Also, note that the base I found compatible with UC inks is not what is used for the UT inks. That requires a specific base from the pigment supplier. Paul www.PaulRoark.com

I would like to do an experiment that requires diluting Epson OEM pigment inks in a 2000P and 2200 printer. Is the H2O/Glycerol mixture at 4:3 a good solvent to use to match the OEM base solvent?

That is what I made it for. (But one does not dissolve pigments, the issue is keeping them in suspension.) What I did was see what chemicals were used in the OEM inks. I wanted to avoid incompatibilities. So, with water and glycerin/glycerol being prime ingredients, I figures this would do it. The Epson base has some other proprietary chemicals in it, but if the dilution is not too much -- say up to 50% -- there should be enough of the others (wetting agents, anti-bacterial agents, etc.) to continue to do their jobs adequately. So, in my experiments, the mix above seems to work fine. I have no real long term experience with it. In my fade tests with B&W inksets made with Epson pigments, the MIS pigments did better.
