I have made numerous ICC and curves using data read by the ColorVision spectrometer 
using Spyder Print 3 for reading the files. I use the 21 step times 4 random image for 
reading the data. It is important that the data be read vertically from left to right. That is, 
Col 30 top to bottom, then Col 70 top to bottom, then Col 5 etc to end of image on the 
right.

Here is what the resulting text file looks like:

I realize that cutting and pasting the text files into this message makes it long but 
hopefully it also makes it more clear.

This is being done using the Leopard patched version of QTR on a MacBook Pro running 
Leopard 10.5.1.
