Digital BW, The Print

Thanks again Tom--

You have been a great help, which I very much appreciate.

I have installed SB's QTRgui program but have not had the time to use it. It 
looks like a fairly steep learning curve for me. Still I will give it a good 
try. This should be fun!

In addition to my 7600 I have a 2200 but it is at my house in Florida. I 
will be there later this week and am looking forward to using QTR to make 
some prints with the EEM/ matte black ink combo. I think there is a 4000 in 
my very near future.

They're "installed" in the sense that QTR knows where to find them.  As far 
as Windows is concerned, they're an unknown (*.quad) file type.  They're 
really nothing more than a text file with some comments (lines beginning 
with #) and a "curve" for each ink.  The curve is just a list of 256 16-bit 
numbers that tells QTR for each pixel's gray value (0-255) how much ink to 
put down (0-65535).
So, in the case of QTR, yes the profile is really just a set of curves.  For 
ICC profiles, the file format among other things are a bit more complicated.
