I have a Hutch target, plus a Kodak IT8, and an Agfa IT8. For a few
years I've been making profiles with PMP 5, and so far I've not been
completely satisfied with any profiles I've made for my drum scanner.
The main weakness is in the shadow rendering. The shadows all loose
their color too soon before becoming black. The deep shadows become
posterized somewhat, and break up ( not a very scientific term, I know
).
My current workflow: Scan target into Lab (ColorQuartet on ScanMate
5000 allows this). Convert to ProPhoto. Edit gray scale with Curves in
PS to neutralize/linearize, saving file to apply to real scans. Convert
back to Lab. Lock down "a" and "b" channels around zero, i.e. pin 2,2
and -2,-2, and adjust those channels for saturated primaries
(r,g,b,c,m,y). Need to use a little Kentucky Windage here. You can't
dial them all in. Save that curve to apply to real scans.
My scans are now better than ever. Much better. Smooth shadow
transitions, excellent color.
PMP does seem to generate decent profiles for my inkjets and for offset
printing. But I still think that some of the "profiles" I made for
offset printing in PS4 using dot gain curves, custom gcr curves, and
gamut measurements of the primaries produced superior results with
respect to the shadow transitions. I constantly wrestle with ugly
transitions in the shadows using PMP generated profiles. Perhaps I
should drop a few more bucks and try Monaco. Who needs a vacation
anyway.
Suggestions are always welcome!
