I’m going to guess Nickolay was right, although I can figure how this could
have happened. Here is what the logfile says for the first row:
[8.484973] 1859 @ A1: 0.074968 0.21457 0.53503 -> 42.06927 -19.460023
11.150365 should be 46.483937 -35.641538 13.647801
I don’t suppose there’s a way to recreate the correct ti2 file and then
regenerate the profile?

Tony,
Run the following in the directory where you have all your Argyll files for
this profile: profcheck –v2 –k –w name.ti3 profile.icm >logfile.log This
will give you a logfile that you can open in Excel and will give you the actual
values of each patch that were created and the subsequent readings for each
patch. You can use the 'spotread' tool to measure individual patches and see
how close they are to the actual values. You could do it in photoshop by
bringing up the target patches and reading it there and then use 'spotread' but
this would not rule out any issues you had during the Argyll workflow though it
sounds to me that something did go wrong. You should never get a warning beep
if you are reading the correct row. Any warning beep means you should reject
those readings. Perhaps you created more than one set of target patches and
read the wrong set.
The best thing to do when starting out with Argyll is to keep things as simple
as possible. Create a one or two page target set, keeping this and all the
resulting files in a single directory. Make sure that you can reliably read
this and generate a profile before going on to a more ambitious set. This will
save you time and money (e.g., wasted paper) and ultimately aggravation. For
many matte papers you can generate extremely good profiles with a three page
target set using an i1 pro since these papers have a smaller gamut than glossy
ones.

Nikolay, first let me apologize to all for top posting. I’m not sure if this is
allowed in the freelist rules.
That’s what I thought (another ti2 file), but there is only one ti2 file which
I generated in the directory where I executed the chartread command – and that
was the name that I inserted in the command string.
I imagine anything is possible, however. How do I check to see if the RGB patch
values match the printed chart?
Thank you.

When I began reading I kept getting a <Warning> after each row with Argyll
thinking I read a row different than what it called for. I surely did not, but
did not understand why I was getting this error for every row. I made sure I
was reading the exact row it asked for. There is only one .ti2 file in the
directory I pointed to (and it's matches the .ti1 file I used for generating
the test charts). I just accepted the data for the indicated row and moved on
to the next. What could this mean?
I'm almost shure that You generated the chart several times and You've just
mixed up the ti2 files. For example, You've run printtarg once, save the chart
image and didn't save ti2. Next You run printtarg one more time and Your
original ti2 was overwrote. You take inappropriate TI2 file for reading, I
suppose.
Check wither the RGB values for patches corresponds printed chart image or not.
Best regards,
Nikolay Pokhilchenko.
