Gene,
The Generic RBG Profile should be located on a Mac here:
/System/Library/ColorSync/Profiles/Generic RGB Profile.icc
In response to your second question, I ran into this more than 3 years ago
and here are my conclusions (short and fast):
When the Epson driver is installed it is setup for Epson profiles and printer
color managemen, and registers a default "Standard" Epson profile for the
printer in ColorSync. If you are printing from an application that handles the
management, versus printer color management, you need to change (or be sure
that) the registered profile for the printer in ColorSync is set to Generic RGB.
Why? Because the in the case of application management, the conversion is
made in the application prior to sending it along through the system of which
ColorSync is part of the system and cannot be bypassed. The application, at
that point does not tag the data with the particular profile use in the
conversion at the application level, but in a way that when Generic RGB is registered
for the printer, no transform occurs at the ColorSync level and thus, the
only transform is at the application level which is what you desire.
Hope this helps.
