Digital BW, The Print

Paul,

To try and clarify:  The Create ICC.exe is a "droplet" program.  You 
take the text file with the data and drag and drop it onto the 
program (and not a shortcut to the program). Create ICC will then 
create the ICC profile in the same folder as the text file.  When you 
do this, a window will open momentarily while the program is creating 
the ICC profile,  but the program does not "run."  I keep a copy of 
the program on my desktop (not a shortcut to the program) and then 
drag and drop the text file on it.  I then have the ICC profiles on 
the desktop and move them to the color folder.

There is a text file in the Eye One folder of the QTR folder and it 
explains the use of the program.  Although Steve has described 
something different, I had problems with the output (to the printer) 
with Create ICC 2.3.1, so I have returned to the version in QTR 
2.3.0.  In a post on the QTR forum, Roy actually suggested using the 
2.3.0 for output until he corrected the problems in 2.3.1.

Best,
Walt
