It is NOT a problem. As someone who has admitted he's never used Epson
printers, take it from someone who's used and owned dozens dating back the
Epson 1200. Off hand I can recall owning and profiling in-house the 2200, 2400,
3800, 3880, 4800, 4880, 4900, 7990, P400 and P800 and I'm forgetting a few in
between! I've also build customer profiles for literally hundreds upon
hundreds of Epson printers. THERE IS NO SUCH PROBLEM!

I'm telling you what I told you earlier: you setup media settings and print a
target, the resolution settings, (see resolution etc, your writing above) has
NO bearing on the profile used when the target was made. Or speed, or finest
resolution etc. You can set the target to be printed at 1440 and print at 2880.
You can set the target to be printed at High Speed and not use that setting
with the resulting profile!

You are posting on the ColorSync list and can't understand a question about
deltaE?

You ask questions but never answer them.

Build the profiles: see the web site instead of posting ridiculous questions.

Then provide some dE values and don't forget, there is no problem you've
invented with your inexperience with Epson printers with respect to profiles
and the settings I've outlined above.
