QTR-Quadtone RIP

Hi Roy, 

I know we had that discussion on private mails. I was just 
mentionning that oppositely to what the Piezo site claims PiezoBW ICC 
is not "perfect" at all out of the box. iQuads might offer a better 
option, but personally I'd rather make my own profile, test them, 
edit them if necessary... This is what I do for color printing and 
they are goods enough to have me produce satisfactory results. Toned 
BW prints I'm not interested which explained why I went for Piezo : 
pure monochrome prints with no metamerism with smooth transistions. 
The last expectation is not met. Working on PC and being used to 
produce with a (quite) simple color managed worklow I was expected a 
lot from the BW ICC. 

I'll test the BW ICC editing (testing also the softproofing once the 
profile is edited) and if this fails QTR will be my only left option. 
I've never use it but I'll learn...

BTW, I have read the K7 presentation page on Inkjet Mall, but it 
seems there's no mention about "real" profiles. They suggest to use 
QTR and some sort of profiles but the recommendation of using QTR 
makes me feel they do not provide actual output profiles.

Thanks for having created this great software.
