I have the I9900, Epson 1280 and Epson 3880, forget about comparing pigment and dye inks! If you want that "Wet" look, super high-gloss and colors that POP, dye inks are still #1 and if you want BLACK-BLACK, dye is the only way to go. There are still some images I still print with dye only. However, the 3880 performs better everywhere else, no comparison and if you want, you can coat your prints with hi-gloss lacquers or automotive acrylic urethane.
Thanks for your feedback.
Have you ever used or heard of anyone using tye CLI-8 ChromaLife inks in the i9900?
