I’m on a PC and have to use the Adobe CPU to print out profiles since this
option has been dropped since Photshop CS5 came out. I suspect that your
problems relate to the MacOS print utility as you did get reasonable results
with the ColorMunki printed charts. The CM software uses its own printing
process for the targets. The fact that you had such high Delta Es leads me to
think that it was the ColorSync software. I’ve done lots of profiles over the
last several years using the Adobe CPU and have never had the type of problems
you have shown. As others have already noted, keep the command line arguments
to a minimum unless there is a very good reason to change them.
Regarding papers I echo what others have already noted. I routinely use Museo
Portfolio Rag and Hahnemuhle William Turner for textured paper. Depending on
how concerned you are about print longevity you may want to visit:
http://www.aardenburg-imaging.com/index.html where there is lots of test
results with various papers and ink sets regarding fade resistance.
Do let us know if it was the MacOS printing of the target that was the issue.
Cheers,
Alan

Hmm... here's something I just noticed. In ColorSync, when I select "Print as
color target", the colors in the little preview window end up changing
drastically. Is this normal? I saved the preview as a PDF on the bottom of the
Print window to show you guys. Here they are:
Original Argyll generated TIF target:

ColorSync Target saved as PDF:

I'm going to try using Adobe's Color Print Utility to see if the same thing
happens during the print.

That sort of thing is much more useful for input (camera or scanner) profiles.
In your case, what you'll want to do is use the "basic" profile you're about to
create to "pre-condition" the patch generation algorithm in targen; see the
"-c" option.
