Any one have any experence with Media street new G8 ink and the epson 9800 printer???
I'm curious why you'd want to go this route when the K3 inks are so good?
Not with the G8 but I recently bought a set of the G6 to try with my 1280. You will most definitely need profiles for these inks. If Media Street has profiles for the papers you use you're in decent shape. I've been using Epson Heavyweight Matte to test the inks and the Media Street profile for it works very well.
It took me several attempts to get a print that I was happy with. Make sure you buy their flushing cartridges and do a very thorough cleaning of the lines and print head. You may need to run a nozzle cleaning at the start of each printing session (I do).
Media Street recommends using Perceptual as the Rendering Intent. I've tried this and wasn't happy so switched to Relative Colormetric and the results are much better.
I'm now getting prints with rich, vibrant colours that match what I'm seeing on screen as closely as possible (taking into account the gamut of the inks) and that are every bit as good as prints I used to make with an Epson 2200. I haven't experienced any issues with bronzing or metamerism either. I'd also say that the overall print quality is better than with the Epson dye inks.
Media Street's tech support people are also very helpful and respond quickly to questions/problems posed through their website.
I have to say though, if you were prepared to pony up the $$$ for the 9800 printer, I'm not sure why you'd do that and not be prepared to spend the coin for the Epson inks.
David, I know this is quite some time after your original post but just thought that I'd add that I've been using the G8 inks with my 2400 for some time now and have been very pleased. I find no issues with the inks and if you have good color profiles for the papers you're using the results beat any other ink system I've seen.
Hope that helps even though it's a bit late.
