The whole point is to get one that uses measured data.  Can you delete the
other channels?  Are you sure it doesn't simply edit a profile? (profile
editors such as PM 5 can not do what we want to do here)

I could not find it - if you know where it is, please let me know.

Who knows but if it is linear already then I need not bother.  It is my
understanding that printers are actually very stable devices (as opposed to
displays) and so they don't really need relinearizing/recalibrating.  A
profile is good enough.

So I only need to linearize if I use a driver/RIP other than the one Epson
intended and this RIP will likely have a linearization feature - eg, QTR.
