WhenI began reading I kept getting a <Warning> after each row with Argyllthinking I read a row different than what it called for. I surely did not, butdid not understand why I was getting this error for every row. I made sure Iwas reading the exact row it asked for. There is only one .ti2 file in thedirectory I pointed to (and it's matches the .ti1 file I used for generatingthe test charts). I just accepted the data for the indicated row and moved onto 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.
