Thanks to all who responded so quickly.
First, I thank Graeme for politely explaining where I went wrong without
rubbing it in. I feel really foolish.
For some reason, despite looking several times at the Argyll web page, I
somehow missed the explicit instructions about how to read strips with
the Eye One Pro. I had looked at the "training video" provided by Xrite
with the product but that was under Windows and it is hard to take it
all in to be used later. (They are shockwave files accessed through a
Windows program and while they are also accessible under Linux using
firefox, it is hard to go to the specific thing you need when you need
it.) In fact, the instructions on the Argyll web page are much better
than Xrite's training video.
I've told Xrite support people on the phone that I am using their
instruments with Argyll, but I don't know if it made much impression.
It may be that they aren't too happy about it since it avoids having to
pay for some of their expensive software---see the example below. But
in my case, I bought the instruments because I could also use them under
Linux with the Argyll programs, and I will emphasize that. In my case,
Argyll expanded their market by one.
Clearly, I should have started from scratch and not used the print I
produced for profiling with a scanner. Xrite provides two sizes, one
with 288 patches and the other with 918. I think I may have to pay them
an additional $200 to get a key allowing me to use the larger size. The
Argyll web page gives tables for other Gretag Macbeth instruments but
not for the Eye One Pro. I am going to start off with 288 which is
what Xrite's Color Match would produce. Any other suggestions would be
appreciated.
One minor comment, '-ii1' doesn't seem to be listed as an argument in
the printtarg Usage summary on the web page, but it is mentioned in the
Scenarios section as an example of the use of the command for the Eye
One Pro. It is also listed as an option if one uses
printtarg --help.
Finally, for displaying the .ps file, I used the ImageMagick program
display. Those programs are very powerful and easy to use on the
command line.
Thanks again to all. I hope I won't have any more problems, but that
may be overly optimistic.
