QTR-Quadtone RIP

I print using Cone Special Edition inks. This ink set begins with sepia
shadows, moves to selenium mid tones and ends with neutral highlights. As a
result, the toning of the final image depends on how much shadow, midtone
and highlight content there is. When I soft proof useing profiles created
with "Create ICC-RGB" I can see how Special Edition inks will tone the
specific image I'm soft proofing. This also includes the tone of the paper
base (i.e. warmer papers will give the specular highlights and areas with no
ink a bit of warmth whereas a cooler paper will cool them).
