Paul,

I could not get connected to the link above detailing the workflow. 
So I went : http://home1.gte.net/res09aij/Monotone_Curves.htm

While I'm all ready to trust your words I can't figure out the 
superiority of avc vs QTR (except direct printing from PS). 

Itinerative spoting of corrections on an acv to get a linear output 
seems to me a much tougher challenge than QTR-linearize at first 
glance. Softproofing is also very straightfoprward with QTR-ICC and I 
just need to send the Tif file to the soft for what I find a perfect 
matching print.

I mean no offence at all saying this, I just can't realise how you 
find the acv workflow superior while I suspect there's a good 
reasoning behing it that I'm missing. Cant you direct me to another 
paper of yours, another link...anything I'll be reading with great 
interest. Thanks.

Olivier
