Ellie, ask him what his workflow was.
He most likely sent a greyscale to the Epson driver. Probably using 
color ink mode.
You could easily duplicate his workflow.

Do you have a custom profile for the Epson driver, or your RIP?
Unless you have a linearized greyscale profile, I'd use the driver and 
its profile.

BO using the ultrachrome inks produces a warm/brown print. Use the 
highest resolution setting.
Color mode prints are cooler, but there are slight hue/tone shifts.
FWIW, I find the color mode, using my own custom profile in PS the best 
route.
Your best prints would likely come from using your RIP.
