I've had very good luck profiling an EX and other six color Epsons using a
setup similar to yours. I use a Digital Swatchbook, always use the
optimization step and generally read one of the larger sets of patches (very
tedious!). Little if any profile editing is needed. In comparison with
some other profile generation methods, I got superior results from
CompassProfile with these printers.
The Epson driver gives so many options for setting up different types of
work flows that its VERY easy to make a mistake where you profile one method
and print using a slightly different one. That may be where your problem
is.
Also, if printing from Photoshop or some other app that lets you apply the
profile before getting to the driver; you might want to try profiling the
driver with it locked onto a series of settings that will yield a decent if
not great print with no profile applied at all. Use the color sliders under
the custom controls in the printer driver to get the printer to produce a
fairly good print with no profile applied. Lock those settings in... save
them so they can easily be recalled later... and profile the printer in that
state. Use the same settings to print and apply your profile from within
software ahead of the driver. I find this works a bit better than profiling
the "no color adjustment" setting.
Try running a print with the "no color adjustment" setting. Especially with
the EX, I think you'll find that it produces a print that is WAY off from
what you expect. Profiling that state means the profile is going to have to
do some very radical corrections. A profile of that type is going to be
more prone to errors and harder to tune than one thats making much more
subtle adjustments to the data.
