I would appreciate hearing more detail on what the Photoshop color space tag
is and how it is used by Epson.

Again, I'm curious about the role of the file "tag".  What info would the
tag have in this case where - I'm assuming - the user has not requested a PS
conversion and is relying solely on the Epson ICM.

Thanks, I'm still trying to understand the  Photoshop-Epson interface so I
can use it confidently.  I sense there are at least a few others on this
list in the same boat.  All help is appreciated.
