I assume you're using the standard UltraChrome in your 3800. Claria is a dye ink used in smaller printers.
Using Claria in wider format is, however, very interesting.
Improving the B&W dye approach is high on my To Do list.

...How are you printing Claria (the Epson dyes) in a 17" wide format Epson 3800? Are you sure you have the ink and printer names correct?Well, I know it's a 3800, I guess I assumed it was Claria in it. I just moved from VA to MI and it's still packed away somewhere so I can't check it. Is it Ultrachrome?
