QTR-Quadtone RIP

Thanks - I don't think the Mac version has that. One just works in the text file, as far as I 
can see, but if I'm wrong, someone please put me out of my misery...  From the error 
messages I've seen when dropping the text file on the application that turns it into a 
profile, it looks as if it does look for data, but it's not clear to me where.  

I realized after I sent the post that I can get rid of the spaces when I save the Excel file to 
text by the rather crude method of shrinking the column width (and reformatting the cells 
as text) but I still need to put a leading zero in each cell that only contains one character. 
Your suggestion makes me wonder if working in columns would be better than rows. I'll 
take a look.

Has anyone worked on a way to figure out the dot gain of combinations of inks at different 
dilutions? The calibration routine makes it easy for the individual inks, but I'm wondering 
what happens in combo - the possible number of combinations is high, so a rule of thumb 
would take some of the guesswork out of designing a profile.

Best,   Ben
