Hi Paul,

In relation to the soft proofing info and general Quad work.

Do you have any info or estimate of the densitometer differences
between some of the various papers you have tested along the way? I'm
thinking in terms of the color differences of your ink formulations
used on different receptive coatings. I see quite significant
differences visually across a spectrum of papers. 
I thought perhaps you may have noted some of this while testing for
fade etc among inks/papers and quantified it or at least noticed this
goes blue that trends magenta or green/cyan etc.

I,m not singling out your quads or complaining because I see the same
effects magnified greatly when printing B&W using color inks as I did
at first on the B&W journey. With those there also were huge shifts
between daylight viewing and incandescent lighting. There was always
some shift but some papers were very extreme in this.

I suspect the coating/paper differences are the reason folks settle on
a few papers for use but it would be nice to be able to dial in
corrections somehow.

Thanks.
Duane
