I have an Epson 870 and a just-opened set of UT2 bottles (filled one
spongeless cartridge, but haven't used it yet).

Just purchased an Epson 2200 and have to get rid of the 870 for space
reasons.

Is there any way I could use the UT2 inks in the 2200 (is there some
sort of mapping between the UT2 to UT7 inks?). Or has someone come up
with a QTR curve for UT2 ink in the 2200 (I had to ask =) ).

On the other hand, is there anyone that wants to purchase an 870 or a
set of UT2 inks (4oz, all full, except the Eboni).

Can I use the Eboni in replacement of the Epson Photo Matte on my
2200? are any profile adjustments necessary, or is it a drop in
replacement?

If I use the Eboni/2200 and print colour or B&W with QTR on semi gloss
paper, and use PremierArt Art Shield spray to eliminate the bronzing,
is that the same quality as using the 2200 with Epson PK instead?

Thanks!
