Roy, Paul All my thanks for taking the time to drop me an explanation. I have to read Paul's papers before anything else now because I can't anticipate why and what in this workflow is superior. The traditional worklow with QTR is pretty straightforward and leaves no room for error. I can't yet imagine acv providing superior control and precision. Except the ability of a direct printing through PS that is a possible advantage, I'm preparing myself for a deep 'dive' into Paul's papers to find out. The most puzzling remains the psd.raw ??? What a tremendous input all of you bring to the BW printing and share with others, is just incredible,.. Great newsgroup with most valuable and admirable people !!!
