RE: [Digital BW] Weak blacks with UT7 PK and PKN

2005-09-10 by Daniel Staver

With just PKN I get a dmax of 2.2, but if I add around 60-70% GLOP in the
QTR curve the density increases to 2.3 on Ilford Smooth Pearl and 2.28 on
Epson Premium Semigloss. I'm leaving the prints overnight now and will do
some more readings later today to see if the densities have changed.

They started shipping the new PK last month I think. It has much better dmax
than the previous PK which was extremely weak on many papers. I haven't
measured the new PK yet, but it appears to have similar dmax to PKN. PK is
brown toned, while PKN is neutral. If you already have PKN you won't really
get much benefit from using PK.
