QTR-Quadtone RIP

Hi Leping.... I tried some split-tones with the curves supplied for
silver rag.  Like you I noticed a real decrease in dmax from the ABW
prints I'd been making (from say 2.4ish to about 2).  Like you I
opened the curves and noticed the Boost K value seemed low.  So I
increased it to 100 and printed some more tests wedges.  Then I
realized that you can't get a truly cool curve if you have the K value
that high, because the K ink is intrinsically warm.
