Baback,
I placed the Palladium-100 text profile in the Files>Doc>QTR
Profiles for Digital Negatives folder, along with a .quad view of the profile
after it was installed. In the .quad view you can see how each of the four inks
is linear from 0% to 100%, but with a different slope for each, which reflects
the difference in Ink Level assigned.
I actually printed the profile with a 21 step wedge on Pictorico with my Epson
4880, and the log density range was 2.32 when measured with a UV transmission
densitometer. I don't know what your density range requirements are for the
pt/pd process you are using, but you can easily increase or decrease the
contrast by changing the Ink Level up or down at an equal percentage of the
four blocking inks in the profile.
At the same time I scanned the digital
negative of the step wedge and also placed it in the same folder so you can see
what the range of tones looks like when the DR is 2.32.
